2.0 SUMMARY OF SITE CONDITIONS

2.1 Site Physical Characteristics

2.1.1 Location

The Woodlawn Landfill Site (Site) is located in a rural area approximately one half mile north of theTownof Woodlawn, and one mile north of the intersection of Routes "275 and 276 in Colora, CecilCounty, Maryland. Rural residences and. undeveloped properties surround the Site in all directions (IT,1992). ~ - - - - - - —... - - --..- --.. - -~

2.1.2 Topography, Drainage, and Vegetation

The land surface in the north-central .area of the. Site slopes gently to the southwest from thetopographic high point near the northeast corner of the "Site. The southwestern portion of the Siteslopes steeply down to a swale and an unnamed stream. The maximum relief within one mile of theSite is approximately 200 feet (IT, 1992J.

Tree cover at the Site is most dense in the southern portion and at the perimeter of the landfillproperty. Grasses and shrubs cover the north-central portion of the.Site where previous landflllingoperations reportedly took place". L " " --^ - - - - - - -------- --. .^ ,-..-

In the south-central portion of the Site, there is a retention basin that was'reportedly designed tocollect runoff from the landfill. A portion of the retention basin contains a palustrine emergentscrub/shrub wetland (EPA, 1993b). Some of the surface flow on the eastern side of the landfillproperty (near Cell B/C) is channeled south, then west, into, the retention basin. When precipitation is•heavy or of long duration, runoff accumulates in the retention basin. The basin discharges through acorrugated steel pipe into a manmade swale "that extends soutliwes'tward into the unnamed streamlocated near the southern tip of the Site. . "

Most runoff from the Site drains to the unnamed, stream. The floodplain of the unnamed stream isoccupied by a palustrihe broad-leaved deciduous forested wetland (EPA, 1993b).

The unnamed stfeairTflows to" the. west-northwest and enters Basin Run Creek (a State-designatedtrout stream) approximately 1.5 miles from the Site. Basin Run Creek discharges into O.ctoraro Creekapproximately 3.5 miles northwest of the Site. Qctorarb Creek flows westward until it joins theSusquehanna River, which flows into the Chesapeake Bay.

2.1.3 Geology

The Site is located in the Piedmont Plateau "Physiographic Province" approximately 5 miles west of theFall Line, which separates the Piedmont from the Atlantic. Coastal Plain Physiographic Province. Thegeneralized geology of the Site areahasjbeen described.in the Remecaal Investigation (RI) as sand andgravel deposits overlying saprolite (decomposed bedrock) and the parent metamorphic bedrock.

The Site stratigraphy from bottom to top can be generalized as follows:

• Bedrock of the Paleozoic Port Deposit Gneiss» Residual soils derived from in situ weathering of the bedrock (saprolite)» Continental Cretaceous Potomac Group (clay and sand)• Tertiary Upland Deposits (gravel and sand)• Holocene-age transported soils, including stream-derived sands .and gravels (alluvium) and

soils washed from hills (colluvium)• Disturbed materials such as waste and reworked natural soils (fill)

Figure 2-1 in the RD Work Plan is a geologic map of the Site area. Generalized geologic cross-sections(figures 2-2 through 2-6 in the RD Work Plan) were completed to illustrate this Site stratigraphy andfeatures.

The bedrock formations of the Piedmont Plateau are generally metamorphic and igneous. In thevicinity of the Site, bedrock is mapped as the Paleozoic Port Deposit Gneiss (Maryland GeologicSurvey, 1988). The Port Deposit Gneiss is described as a strongly deformed intrusive complex ofgneissic diorite and blollte diorite; strongly foliated and sheared. According to the borehole Hthologiclogs recorded during the RI, two bedrock formations underlie .the Site: a gneissic granite and ametadiorite. Based upon drilling logs from six borings near the perimeter of the landfill, the gneissic "granite underlies the saprolite across much of the Site, except the extreme northwestern portion. Inthe northwestern portion of the Site, the uppermost bedrock unit is described as metadiorite. Thegneissic granite is described in each of the remaining bedrock wells at the Site and appears to bethicker on the east-southeastern portion. The metadioiite was encountered below the gneissic granitein the eastern portion of the Site, Two of "the bedrock well boring logs indicate that the gneissicgranite and metadiorite are intertongued and are described as banded at depth. The gneissic granite isdescribed as pink and coarsely crystalline with weak foliation. The metadiorite is described as black,white, and finely crystalline with pronounced schistosity. Both the gneissic granite jmd themetadiorite contain interlocking crystals of feldspar, quartz, hornblende, mica, and other minerals.These minerals contain silica, iron, aluminum, manganese, calcium, sodium, potassium, and trace ...elements. Upon weathering, the gneissic granite and the metadiorite break down into clay minerals,silica, and oxides of iron and manganese. The iron and manganese oxides become" more soluble inoxygen-poor or reducing environments, and can be transported by the groundwater. This naturalsource may account for som"e"of the iron and manganese in the groundwater at the Site (IT, 1992).

A thick layer of residual decomposed bedrock (saprolite) overlies the bedrock at the Site. Saprolite isdefined as a soft, clay-rich, thoroughly decomposed rock.fornaed in place by the chemical weatheringof meiamorphic and igneous rocks. (Bates and lackson, 1984). Saprolite is characterized by .thepreservation of structures that were present in the unweathered rock. The saprolite encountered inthe borings at the Site has, over time, been described as sand, silt, clayey silt, or decomposed rock onthe Site boring logs. The saprolite ranges in thickness from approximately 15 to 90 feet at the Site.The saprolite is thickest in the northern portion of the Site and thinnest in the southern portion of theSite.

According to Spotts, Stevens, and McCoy (1980), Cretaceous Age Potomac Group sand and claydeposits lie above the saprolite in portions of the Site.. Alluvium and colluvium also lie above thesaprolite in portions "of the" Site. Both the Potomac Group" members and "the alluviurh/colluviumcontain layers of.silty clay and clay in some areas of the Site. ..

Sand and gravel deposits on the topographic high at the Site have been described in various Sitereports as" the Upland Gravel unit, the Upland Deposits, and the Bryn Mawr Gravel. According to theGeologic Map of Cecil County, Maryland (United States Geological Survey, 1986), the Miocene UplandGravel is a quartz gravel unit with scattered lenses of cross-stratified quartzose sand and local lenses,slabs, and balls of light gray clay. .The ujDper P°rtion of the Upland Gravel has been oxidized to'reddish-brown. Quaternary 'alluvium also consists of sand, silt, clay, and gravel deposits. •

During the time when thejsand and gravel operation was in existence at the Site, portions of theUpland Deposits, the alluvium/colluviumV and possibly the Potomac Group sands were excavated andremoved from the Site. The fill at. the Site consists of materials that may have been deposited intothese excavations, rearranged alluvium/colluvium, and mounds of reworked sand and gravel.

2.1.4 Hydrogeology

The saprolite and bedrock may be hydraulically connected in.the area, of the Site.. The water tableacross most of the Site appears to occur within the sapiolite." Near the southwestern corner of the Site(near monitoring well ITB-4), the unconsolidated material was unsaturated and groundwater wasencountered only in the bedrock. ... . , ...

Previous reports indicate a water "table mound near the northeast corner of the Site. Groundwaterfrom this mound appears "to flow radially .outward. Because, most of the monitoring wells onsite arescreened at varying depths, local groundwater flow directions cannot be readily established from theavailable data. Local groundwater flow directions are likely influenced by local topography, therelative permeabilities of the various units beneath the Site and sources of groundwater recharge. Theregional groundwater flow is toward the JSusquehanna River and Chesapeake Bay, to the west-southwest. . . . . . . ,

There appears to be a perched water zone above, the water table, which was intercepted in severalborings. Three wells, ITP-1, ITP-2,_and ITP-3, were installed to.investigate this unit. Because these.wells are oriented roughly in a straight line, information regarding groundwater movement in this zoneis limited. ' " - - ----- • • - _-• ~ .. . . ; _ ^. ._. ^

Potable water at the Site and in the surrounding area is obtained from private wells. Most of thewells, including the well that serves the transfer station_(TSTA-1), reportedly tap fracture systems inthe bedrock'water-bearing zone. Some potable water wells in the region, including the well on Parcel506 Vo th"e~soiith"~b"fThe landfill, may also tap groundwater in the unconsolidated material above thebedrock (IT, 1992, Section 2,1.2.2). ;;.-.;.

2.2 Groundwater Quality

Available data on groundwater quality include the. following:

• Historical groundwater monitoring data collected prior to the RI (1978-1988"J"as presented inITs computer database

• Groundwater monitoring data collected during the RI (1988-1992) as presented in ITscomputer database

Recent water level and chemical quality data collected during the HLA January 1995 samplingevent

The recent January 1995 data have not been fully evaluated.

The available monitoring data indicate that several organic and inorganic compounds have beendetected in groundwater. The Record of Decision (ROD) establishes Groundwater Cleanup Levels forthe following constituents in the Site groundwater: 1,2-dichloroethane, tetrachloro.ethene,trichloroethsne, vinyl chloride, benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene,benzo(k)fluoranthene, bis(2-ethylhexyl)phthalate, chrysene, pentachlorophenol, ajdrin, alpha BHC,heptachlor, and arsenic. The ROD also establishes a procedure for determining Groundwater CleanupLevels for the following constituents: endosulfan I, arsenic, cadmium, manganese, mercury andvanadium. These constituents are presented with their cleanup levels in Tables 9 and 10 of the ROD(Appendix A of RD Work Plan).

Preliminary review of the data resulted in the observations are discussed in Sections 2.2.1 and 2,2.2." -'Based on the observations presented below and the current uncertainty in groundwater flow patternsat the Site, additional groundwater monitoring wells will be installed and sampled during the pre-design investigations, as described in Section 4.2.3.3.6 of the RD Work Plan.

After preliminary evaluation of the historical analytical 'database, the chemicals selected in the ROD .".-(as listed above) were organized into contaminants of primary and secondary concern with regard tothe remedial design. Contaminants of primary concern were those that were detected most frequentlyand/or will likely drive groundwater recovery and/or treatment technologies. Contaminants ofsecondary concern were those that were found only in a few wells or sporadically throughout the Siteand will likely not drive recovery and/or treatment technologies.

2.2.1 Constituents of Primary Concern

2.2.1.1 Vinyl Chloride

Vinyl chloride has been detected in samples from 28 of the landfill monitoring well locations. Vinylchloride has been detected consistently in wells in the vicinity of Cells A and B/C since 1981. Vinylchloride concentrations in 9 of the well locations generally increased from 1982-to 1.986 and declined

relatively rapidly from 1987/1988.,to the present. These conditions were observed in wells B-l/ITB-11,B-4, B-6, F-2, F-5, F-6, F-8, F-10, arid OW-2. The general distribution of vinyl chloride in Site 'groundwater monitoring wells in November 1990 is shown in Figure 2-7 of the RD Work Plan.

Groundwater samples from well F-6 have .historically exhibited the highest concentrations of vinylchloride at the Site". Vinyl chloride concentrations in samples from well F-6 rose to. a maximum of1,176 ugfL in 1987. Since that time, "vinyl chloride concentrations in samples from this well havedeclined steadily. Historical vinyl chloride data for groundwater samples from many of the other wellsindicate the same trend. Chemical concentration data versus time graphs for wells F-2, F-5,'F-6, F-8,F-10,'and B-6 showing changes _in vinyl chloride concentrations throughout the historical groundwatersampling are included in Appendix. B of the RD Work Plan. These wells were selected as examplesbest illustrating this trend. The trend of decreasing concentrations of vinyl chloride with time wasalso observed in wells B-4,-ITB-l and OW-2.

2.3 Environmental Setting

The Site is located in a rural area dominated by agricultural land use. Influences from agriculturalactivities are evident in most of the ecosystems surrounding the Site. Other land use types within one.mile of the Site include an abandoned gravel mine and an automobile salvage yaxd.

The Site itself is domin'ated (greater than 60 percent of the cover) by a mix of herbaceous andscrub/shrub rangeland. Areas of deciduous forestland also have been identified on the Site. In 1992,IT delineated a small [less than one acre) area of palustrine emergent scrub/scrub wetland habitat inan area originally excavated as a retention basin. An unnamed stream traverses approximately 150linear feet of the extreme southern portion of the site. Section 4.4 of the RD Work Plan is designed toinventory and, where appropriate, delineate habitats and other environmental conditions within the .Site boundaries and in areas outside of the Site boundaries as necessary to evaluate potentialenvironmental impacts related to the Site.

8.0 SITE OPERATIONS

Zones will be established to prevent or minimize exposure of personnel to hazards by establishingboundaries to reduce migration 'of contaminants into clean areas, -For this site, a three-zone, approachwill be..used for most field activities. The zones will he identified during safety briefings and will beclearly marked by traffic cones, barricades, signs", or other means.' These three zones shall be des-ignated as the Support Zone, the .CDnt_aminaU'on'.ReduatiQn.Zone, and the Exclusion Zone. Work areaentrance and exit shall be through controlled access points established for each work location.

8.1 Support Zone

The. Support Zone is the clean area in which the possibility of encountering hazardous materials orconditions is minimal. Therefore, personal protective and respiratory equipment are not necessary.Inside the Support Zone, *1he.following will be available: an effective means of communication, accessto first aid supplies," a fire' extinguisher, drinking water, an£ other appropriate support facilities. The .Support Zone shall also serve as the main, point of contact for visitor check-in and initiation ofemergency services when necessary.; - . - - - -

8.2 Contamination Reduction Zone

The Contamination Reduction Zone (CRZ) is the area where equipment and personnel aredecontaminated before leaving the Exclusion Zone. Personnel will'remove and/or decontaminate PPE,and place it in appropriate containers. Site vehicles and.equipment will also be decontaminated in theCRZ. .The.CRZ will consist of a decontamination pad (temporary or permanent); a means .of washingprotective equipme'nt; site vehicles, and equipment; containers for.liquids, solids, and PPE; first aid.supplies; an eyewash/emergency shpwer; and afire extinguisher.

Eating, drinking, chewing gum or tobacco, smoking, or any; practice that increases the probability ofhand-to-mouth transfer and ingestion of material is prohibited in the "CRZ.

8.3 Exclusion Zone

The Exclusion Zone'includes the work .activities at the Site (e.g., drilling, sampling, etc.)- Onlyauthorized, trained, and qualified personnel with the appropriate, personal protection and respiratoryequipment shall be admitted. Personnel entering the Exclusion Zone must use the buddy system. If asituation arises where the buddy system cannot be used, constant visual contact will be maintainedwith at least one'oiher worker. The maximum, distance.for visual contact is 200 feet.

Work activities within the Exclusion Zone pose" the greatest possibility of exposure to personnel andequipment. The Field Operations Manager shall be responsible for controlling the access points andkeeping bystanders, and unauthorized, personnel to a minimum. The Exclusion Zone..will be clearlymarked with flagging, barricade, tape, traffic cones, or other signals to limit access.

A "hot line" will be established between contamination reduction zones and the exclusion zone. Uponexiting the exclusion zone, no one will cross the "hot line" without first implementingdecontamination procedures. For drilling, well installation, sampling, and other intrusive work, a

9.0 PERSONAL PROTECTIVE EQUIPMENT AND ACTION LEVELS

PPE is required to be'worn by workers for all onsite work and whenever there is potential to .come intocontact with contaminated, soil, water, 'or hazardous substances~ar~canditians. Initially, Modified LevelD PPE will be used for intrusive activities 'such as drilling, soil and groundwater sampling, and otheractivities involving the possible "contact with contaminated soil, or water. When conducting activities"where concentrations of organic-vapors in the breathing zone potentially may be elevated abovebackground levels, a fan or blower should be used and o e;cted .d_ownwind over the. monitoring well,borehole, test pit, or drum (of purge water] in an effort to maintain organic vapor concentrations equalto background levels or below action levels. If airborne concentrations of contaminants in thebreathing zone cannot be maintained at background levels, work must be conducted in Level C orLevel B PPE, "depending on concentration and type of airborne contaminant(s).- PPE Levels may be..upgraded or downgraded by the SHSO_as field conditions, warrant. The use__of fans or blowers may bediscontinued when Level B PPE is being utilized. . "

Because vinyl chloride and mercury are" known'to be present, air monitoring is vital. Monitoring mustbe initially conducted using a Photoionization Detector [PID] or.Flame lonization Detector [FED].Should contaminants be .detected .by the PlD or FID, Draeger tubes for vinyl chloride should then beused to determine if vinyl chloride is present. If vinyl chloride is present (indicated on the detectortube), PPE should be'upgraded to Level B. .If .vinyl chloride is not present and there are sustainedairborne concentrations above background but not more than 5 parts per million, (ppm), an upgrade toLevel C PPE is sufficient. Level B PPE 'will be utilized where sustained airborne concentrations oforganic vapors exceed 5 ppm but not more than 500 ppm. Should sustained airborne concentrations,...of organic vapors in the breathing zone exceed 500 ppm," the work area will be evacuated and theDHSO-notified. If mercury is detected on the mercury-vapor meter, engineering controls should be. .implemented. If mercury vapors persist, Level C PPE should be.used. Whenever possible, engineeringcontrols such as large fans or blowers should be .used to mitigate inhalation hazards rather thanresorting to PPE. "7"1". .."_!LI "• "". _._ ..: .__.". .. . . . . .

10.0 AIR MONITORING AND SITE OPERATIONS

This section-describes instruments and procedures that will be used for air monitoring activities. Itmay not be necessary to perform*all of these activities at every work location. Decisions regarding airmonitpring will be made by the DH.SQ and the. SHSO;'...

A daily monitoring log will he kept by the SHSO "for each piece of air monitoring equipment. Thefollowing information will be..recorded:. .. ' ._..;. ......

* Name and model number of the equipment -• . Calibration information* Field work to.be performed - - - . . . . .• A i r monitoring results 'and monitoring locations " . " " ' "• P P E worn . • • - . - • . . _• Accidents or incidents ' -• Unusual occurrences ".and personnel complaints

Continuous air monitoring will be.conducted during intrusive site activities.. Measurements must.becollected upwind, downwind, in the breathing zone of the workers conducting the work, and at themost feasible location closest to the source of the potential contaminant(s). Monitoring conductedupwind will establish background concentrations. Monitoring conducted downwind will be measuredat the perimeter of the. Contamination Reduction Zone (CRZ) to check that contaminants leaving thework area(s) are within-acceptable levels in order to protect .the general public. Monitoring conductedin the.-breathing zone of the workers will be used to establish the appropriate level of PPE to beutilized. Monitoring .conducted at. the most feasible location closest to the source of potentialcontamination will determine the maximum expected concentration(s) of on-site contaminants.

10.1 Gases and Vapors

A PID or a FID will be used to monitor breathing zone concentrations of organic vapors. Monitoringwill be conducted continuously during sampling or intrusive activities. Should air monitoring with thePID or FED indicate concentrations of VOCs above background, blowers/fans should be used to mitigatebreathing hazards. Should VOC concentrations remain sustained above background levels, detectortubes for measuring "vinyl chloride should then be. used. Appropriate PPE can then be selected. Theuse of fans or blowers may.be discontinued when Level B PPE is being utilized. Calibration ofmonitoring equipment will be performed daily before startup of work. Calibration gas to be used willbe specific to the instrument per manufacturer instructions. HLA's.standard operating procedures forfield calibration and maintenance, of direct reading instruments, personal sampling pumps, anddetector tubes are":pres"ented in Appendix G. - —.-- - •-- -------

10.2 Explosion Hazard

A combustible gas indicator (CGI) will be used at the work areas, as appropriate to monitor thepossible presence of flammable gases (e.g., methane) or vapors. Equipment calibration will beperformed daily before startup of work in accordance with manufacturer instructions. The alarm will...be set to 10 percent of the lower explosive level (LEL). If feasible, the calibration gas used will bespecific to the combustible gases that may be present (methane)."

Periodic monitoring for the presence of combustible gases will be performed at the sampling point,where appropriate. If the monitoring Instrument indicates the LEL is_ greater than. 10. percent,personnel must leave the area. Supply fans should.be used to_lower the LEL. Personnel must notreenter the area until the LEL is less than 10 percent.

10.3 Confined Spaces

Before entering a confined space, an oxygen meter must be used to measure the oxygen concentrationin air. If the oxygen concentration is less than 19.5 percent or greater than 23.5. percent, entry to thespace is prohibited. Supply fans should be used to ventilate the area. If the oxygen concentrationcannot be stabilized between 19.5 and 23.5 percent, Level B PPE must be donned to. enter the confinedspace, (Note: Entry to a cdnfrcted space requires that a permit be obtaineQ-from-ihe DHSO).

Following measurement of the oxygen content, a CGI must be used to determine: if an explosiveatmosphere exists. Procedures for use of the CGI are outlined in Section 10.2.

Following use of the CGI, a PID, a FID, and/or any other appropriate air monitoring device must beused to monitor the,afr for potential toxic air contaminants. HLA's Permit-required Confined Spaces'.Policy is included as Appendix F.

1O.4 Respirable Particulate

A MEE RAM-1 respirable particulate monitor will be used at the work areas, as appropriate, to monitorthe possible presence of respirable particulates. Equipment calibration will be performed daily beforestartup of work in accordance with manufacturer instructions. Should the monitoring instrumentindicate respirable particulate levels of 2.5 mg/m3 or greater, Level C PPE will be donned and dustsuppression methods will be implemented [see Section 7.9).

Woodlawn Landfill is heavily wooded and overgrown with tall weeds, grasses,'and undergrowth.Because ticks thrive in this kind of "environment and because ticks may be carriers of Lyme Disease,techniques to prevent tick bites must be utilized for all onsite activities when temperatures .exceed 50degrees Fahrenheit. Tick prevention techniques: include the use of Tyvek suits or protective coverallswith the.open end of the pant legs tucked into socks. - Duct tape should then be. used to tape the. legsof the coveralls to safety boots. A tick repellent should then be applied. Care should be taken tofollow the manufacturer's instructions on the proper use and application of the. repellent. Avoidsample contamination with tick repellent. Additionally, frequent "tick checks" should be conducted tolocate and remove ticks prior to being bitten. In the event of a tick bite, carefully but 'firmly removethe tick intact without squeezing its abdomen- Place the tick in_an escape-proof container or wrap itin a piece of duct tape. Label the container or duct tape as to its contents, the name of the personwho was bitten, and the date, then notify the DHSO within 24 hours for further instructions.

11.1 Surveying and Brush Clearing

Surveying, brush clearing, and surface geophysical, investigations should present the lowest chemicalhazard to personnel, since these .operations are nonintrusive and result in minimal disturbance of1contarninated areas. Level D PPE has been initially selected for these tasks unless air monitoringresults exceed the action levels, in which case the PPE will be upgraded appropriately. Whensurveying well elevation's,.wells.must be.allowed to vent for at least two minutes prior to conductingwork near the well and should be approached from an upwind direction only.

When surveying is conducted in transportation zones such as streets, safety vests must be worn andcones and/or barrier ribbon must be used to demarcate the survey area.

11.2 Water Level Measurements, Aquifer Testing, Recharge Testing, andSampling of Groundwater Monitoring Wells

Modified Level D PPE has been selected for initial water level measurements and sampling of thegroundwater monitoring wells. When conducting these activities, the well head should first be openedand allowed to vent prior to performing the work. Personnel shp.uld approach the wells from anupwind direction. .

Should concentrations of VOCs and/or mercury vapor be elevated above.background levels,institutional cofitrols-such'as supply fans must be introduced in order to maintain backgroundconcentrations". If concentrations of VOCs in the breathing zone cannot be maintained at backgroundlevels but are less than or equal to 5 ppm, detector tubes must be. used to determine the presence ofvinyl chloride. If vinyl cblorideJs not present and mercury is.no/longer detected, Level C PPE can beutilized. If vinyl chloride is present, mercury is present; or airborne concentrations are greater than 5

11.3 Soil Boring, Monitoring Well, and Test Pit Installation and PercolationTesting

When supply fans are utilized, Modified Level D PPE may be used for driving soil borings, installingmonitoring wells, and geologic logging activities. Supply fans/blowers should be used during theseactivities to mitigate potential inhalation hazards. Follow the air monitoring procedures outlined inSections 10.1 and 11.2 above. The SHSO may upgrade or downgrade the level ofPPE if airmonitoring and review of sampling results indicate that it is appropriate. Personnel should remain inan upwind direction whenever possible. -

The one-call utility mark-out system (MISS Utility) will, be called to mark the locations of publicutilities prior to any drilling or excavating activities. If possible, nonintrusive screening will be . Lperformed at each well or boring location to screen for the.presence of buried utilities, drums, tanks,or other objects prior to drilling. - . .

If drilling activities take place on or near roadways or railways, safety cones, safety vests, barrier.ribbon, or other types of highly visible placarding or 'warning devices will be used. HLA's Excavationand Trenching Policy is included as Appendix E.

11.4 Stream-Water and Sediment Sampling, and MacroinvertebrateSurveying

Because surface waters and stream sediments may be contaminated with, metals and SVQCs,reconnaissance and sampling activities in areas where water is present will require Modified Level D -PPE. Eye protection must be worn and potable rinse water and an emergency eyewash must beavailable. Should work require the use of a boat or raft, life preservers must be .w_arn at all times.when on the water. Should confined space entry be required ui order to obtain water or.sedimentsamples (e.g.t entering a storm sewer), procedures outlined in Section 7.10.and in HLA's Permit-required Confined Spaces Policy must be followed. A minimum of Modified Level D PPE will berequired for confined space work. HLA's Permit-required Confined Spaces Policy and a blank confinedspace entry permit are included in Appendix F.

11.5 Installation and Sampling of Gas Probes, Soil Gas Surveying, andSampling From Air Strippers/Groundwater Treatment Systems

Initially, Modified Level D PPE will be required for the installation and sampling of gas probesv.soil-gassurveying, and sampling from air strippers and/or groundwater treatment systems. Air monitoringmust be conducted frequently to monitor the adequacy of the PPE bering utilized. If conditions andair monitoring results warrant, the SHSO may upgrade or downgrade PPE as appropriate.

« If the spill occurs on a porous surface (e.g., soil, gravel) mark the area in preparation forexcavation if that is determined to. be the appropriate response action. If the spill occurs onconcrete, asphalt, or similar material, use sorbent material to contain the spill. Absorbentmaterials will be kept in field vehicles and in the support facility. Cover the area with soil,'atarp, plastic, or other appropriate material if the spilled material is volatile and cannot becleaned u p immediately.. . . .

• Call the Field Operations Manager" an'd SHSO, or the local emergency response organization .- - [as applicable), to report the incident. See Section 14.1 for emergency telephone numbers. If

possible, two HLA personnel must remain near the work area .in a safe location 30 feetupwind of the spill until emergency response representatives arrive.: •

• • • Dependent on the'location and chemical nature of the spilled liquid, initial response action ;- •may require donning Level C or Level B PPE.

/14.4.7.2 Spill Site Decontamination

HLA and subcontractor site personnel involved in the response action will undergo limited personaldecontamination upwind of the incident site. Further decontamination will be completed at thedecontamination trailer in the. support zone. The SHSO. will authorize field personnel to leave the jobsite or continue work, as appropriate. The Field Operations Manager will provide guidance regardingdecontamination and/or disposition of equipment and vehicles. . .

If personnel come in contact with fuel, they should remove and dispose contaminated PPE, change outof contaminated field clothing, and wash exposed skin with soap 'and water.

14.4.7.3 Cleanup Materials and Used Personal Protective Equipment Disposal

14.4.7.4 Spill Prevention

To rriinimize the potential for a spill, you should follow these guidelines: . ..,,-„- .-. .. , , _ ..

• Receive instruction concerning recognition of potential spill problems, preventative main-tenance actions, and increased safety awareness, .. -

• Inspect stored materials at the beginning of each work shift. The container condition, as wellas any notation of leal s or staining that may be related, to pr, an indication of a potential spill,will be recorded in a field logbook. Any abnormalities and steps taken to remedy the situationmust be reported immediately to the Field Operations Manager.

• Inspect transfer vehicles arid equipment at the beginning of each day. Equipment conditions, .as well as any notation of leaks or staining that may be related to or .indicative of a potential .spill, will be recorded in a field logbook. Loose aruLoovorn connections and worn hoses willalso be noted. Any abnormalities must be reported immediately to the Field Ope'rationsManager and steps should be taken to remedy the situation before continuing transferactivities. . -

• Make sure materials being stored are compatible with the containers in which they are beingstored. Materials that are likely to react when exposed together will not be stored in the samearea. Caustics and corrosives will be stored in separate cabinets affixed with caution labels. _SpHlable items, if stored on shelves, will be no higher than 4 feet off the floor surface. .:.(Tbisheight is to limit the potential for getting a toxic substance in the eyes).

• Store containers larger than 1 gallon separately from smaller quantities, JJ-arger liquid storagecontainers will be stored in a warehouse and must have a secondary cont.ainm.ent system.This system can be as simple as a liner with a berm constructed of 4-anclL.high boarding andshould be able to contain an amount 10 percent greater than that of the. original container. .. •

• Transfer liquid with catch basins under each joint OT valve or with the hose or pipe lined sothat no liquid can escape.

14.4.8 Responsibilities of Field Personnel

HLA's Responsibilities • - • . .

• Wear the correct and appropriate PPE for the task.• Use monitoring equipment "applicable to the anticipated hazards (i.e., CGI, FID, PID, etc.).• Have a decontamination area set up for fieldwork. - .• Use approved decontamination procedures."

2.0 GENERAL

A. The OSHA Bloodborne Pathogens Standard does not apply lo HA, HCS, and HLA employeesbecause these employees are not "reasonably anticipated11 to come in contact with blood andother potentially infectious materials as a result of performing their job duties. This standard isIntended to apply to those types of employees who as a part of their assigned duties may comeinto contact with infectious materials. These include medical personnel, ambulance personnel,medical laboratory personnel, funeral employees etc. NOTE: "Good Samaritan" acts such asassisting a co-worker with a nosebleed or laceration are not be considered as occupationalexposures and are not subject to the OSHA Bloodborne Pathogens Standard.

B. HA, HCS, and HLA employees are cautioned however, that any contact with blood or other bodyfluids or tissues may be a source of infectious materials. These infectious materials include butaie not limited to; cerebrospinal fluid, synovia! fluid, pleura! fluid, amniotic fluid, saliva, semen,vaginal secretions, any body fluid visibly contaminated with blood and all liody fluids insituations where it is difficult or impossible to differentiate between body fluids,

C. HA, HCS, and HLA employees are advised that the best protection from infection caused bycontact with an infectious material is washing the exposed body parts with soap and water andavoiding getting body fluids into open breaks in the skin. Disposable latex gloves used asundergloves when working with hazardous waste material can provide added protection frominfectious materials.

D, Any HA. HCS, or HLA employee who is exposed to potentially infectious materials on the jobshall immediately contact their supervisor who will in turn contact the DHSO for advice. TheDHSO shall call the contract Medics! Director (ENVIRONMENTAL MEDICINE RESOURCES,EMR) for advice at 1-800-229-3674. The Medical Director CEMR) will direct the appropriatetesting and any therapy which is required. For after hours situations, leave a message on; the ".answering machine .arid you will be called back by EMR.

Hazardous atmosphere means an atmosphere that may expose employees to the risk of death,incapadtation, impairment of ability to self-rescue (that is, escape unaided from a permit space),injury, or acute illness from one or more of the following causes:

1. Flammable gas, vapor, or mist in excess of 10 percent of its lowerjQammable limit (LFL)or lower explosive limit (LEL];

2, Airborne combustible dust at a concentration that meets or exceeds its. LFL or LEL;

Note: This concentration may be approximated as a condition in which the dustobscures vision at a distance of 5 feet (1,52 m) or less.

3. Atmospheric oxygen concentration below 19,5 percent or above 23.5 percent;

4. Atmospheric concentration of any substance for which a dose or a permissible exposurelimit is published in Subpart G, Occupational Health and Environmental Control, or inSubpart Z, Toxic and Hazardous Substances, of 29 CFR 1910 and which could result inemployee exposure in excess of its dose or permissible exposure limit;

Note: An atmospheric concentration of any substance that is not capable of causing"""" death, incapacitation, impairment of ability to self-rescue, injury, or acute illness due to

its health effects is not covered by this provision of the standard.

5. Any other atmospheric condition that is imniediately dangerous to life or health.

Nole: For air contaminants for which OSHA has not determined a dose or permissibleexposure limit, other sources of information, such as Material Safety Data Sheets thatcomply with the Hazard Communication Standard, §1910.1200 of 29 CFR, publishedinformation, and internal documents can provide guidance in establishing acceptableatmospheric conditions.

Immediately dangerous to life or health (IDLH) means any condition that poses an immediateor delayed threat to life or that would cause irreversible adverse health effects or that wouldinterfere with an individual's ability to escape unaided from a permit space.

Isolation means the process by which a permit space is removed from service and completelyprotected against the release of energy and material into the space by such means as: blankingor blinding; misalign Trig or removing sections of lines, pipes, or ducts; a double block and bleedsystem; lockout or tagout of all sources of energy; or blocking or disconnecting all mechanical .linkages. _

Non-permit confined space means a confined space that does not contain or, with respect toatmospheric hazards, have the potential to contain any hazard capable of causing death orserious physical harm.

Oxygen deficient atmosphere means an atmosphere containing less than 19.5 percent oxygenby volume.

APPENDIX G

EQUIPMENT CALIBRATION AND MAINTENANCE

rtR30.8!7Q

This appendix presents Harding Lawson Associates' (HLA's) standard operating procedures for field

calibration and maintenance of direct reading instruments, personal sampling pumps, and detector rubes that

may be used during field activities. Each, equipment item is described and the calibration, operation, and

maintenance procedures are detailed to the extent necessary to ensure proper care and use. Detailed

procedures are provided in instrument-specific manuals from each manufacturer. .

These standard operating procedures are intended to ensure that equipment is properly maintained

and operated. These procedures were developed on the basis of the folio wing assumptions:

- Procedures are consistent with the manufacturer's calibration, operation, and maintenanceguidelines.

- Equipment calibration, operation, and maintenance procedures will be performed by properlytrained HLA personnel.

- Only designated personnel will calibrate, operate, and maintain certain instruments.

- Records will be maintained to allow tracking of the calibration, operation, and maintenance of agiven instrument.

PHQTOIQNIZATIOK DETECTOR (HNU PI 1Q1/HNU DL101/PHOTOVAC MICRQTIP) . ....

Theory of Operation ., '' - . . . . . . .

The portable photoionization detector (PID) detects the concentration of organic gases as well as a

few inorganic gases. The basis for detection :is"the ionization of gaseous species. Every molecule has a

characteristic ionization potential (IP) that is the energy required to remove an electron from the molecule,

yielding a positively charged ion and the free electron. The incoming gas molecules are subjected to

ultraviolet (UV) radiation, which is energetic enough to ionize many gaseous compounds. Each molecule is

transformed into charged ion pairs, creating a current between two electrodes. - -

Three lamps, each containing a different UV light source, are available for use with most PIDs.

Ionizing energies of the lamp are 9.5,10.2, and 11.7 electron volts (eV). All three detect many aromatic and

large molecule hydrocarbons. The 10.2eV and 11.7eV probes, in addition, detect 'some smaller organicj

molecules and some halogenated hydrocarbons. The 10.2eV lamp is the most useful for environmental

response work because it is more durable than the 11.7eV lamp and detects more compounds than the 9 ,5

eV lamp. The following sections detail the proper calibration and field maintenance methods to be used

with these PIDs. " - - •

HNU PI 101 _ „__ .. .. ..,....,_.. .. '. ., ......,_.,,_.

The HNU PI 101 PID is'designed for trace; gas analysis in ambient air. The HNU PI 101 is

factory-calibrated with certified standards, of benzene, vinyl chloride, and isobutylene, with the reference

standard being benzene. Because of the. inherent toxicological risks associated with benzene and vinyl

chloride, the primary calibration standard to be used should be isobutylene. When calibrating the unit with

100 parts per million (ppm) isobutylene, the "SPAN control should be set at 9. 8 and the unit should read

approximately 70 ppm. This method of calibration converts" the response of the unit to isobutylene to yield a

direct reading of benzene that is based. on the response factor of the unit using a 10.2eV probe at a span

setting of approximately 9.8. More simply stated, the required reading for calibration will be as follows:

= Isobutylene ppm x ' Photofoaafion sensitivity (isobutylene)- photoionization sensitivity" "(benzene)

= 100 x-7/10" •-——--- -•-;• - - - - - * - - - _-, —

="70 ppm * "- " -; - •"* "•-----=--=---" - - -.--:-------=-- ------- ----- -.--.-.-.. - .

When using probes with 9.5 eV or 11.7 eV lamps, consult the user's manual for photoionization sensitivities -

and required SPAN control settings because these units may change for each individual lamp,

In cases where hazardous chemicals have been- identified, the HNU PI 101 can also be calibrated to

provide direct reading results.of these chemicals. rPlease consult the user's manual and the Designated

Health and Safety Officer (DHSQ)"to select chemicals for concern of appropriate calibration. The steps

calibration method for the HNU""PI"i"Oi"with a 1072eV lamp follows:

1, . Identify the probe by the lamp label. If a question exists, disassemble the probe and inspect thelamp. The energy of the lamp should be etched into the glass envelope.

2. Connect the "probe to the'readout assembly, making sure-the red interlock switch is depressed bythe- ring on the connector

3. Set the SPAN control potential to 9.8.. " . . " "

4. Battery check - turn the function switch to BATT;. The needle should be in the green region. Ifit is not, recharge the battery.

5. Zero set - turn the function switch to STANDBY. In this position, the lamp is off and no signalis being generated. Allow the unit to sit for a minute tojvarjmjhe parts. Set the ZERO pointwith the ZERO set control.

.6. Fill a dedicated tedlar bag with the 100 ppnf isobutylene in air SPAN gas.

E-2

AR308I72

7. Turn the function switch to the 0 to 200 range "position. Attach the sampling bag to the probeinlet. Adjust the SPAN control setting to read approximately 70 ppm at a span setting of 9.8,

8. Record the units achieved at the set SPAN control and the calibration phase used.

9^ Lamp cleaning - If calibration cannot be achieved at the desired span potential, the lamp must becleaned. (See specific instrument manual for instructions)

HNU DL-1Q1-2

The HNU DL-101-2 applies microprocessor capabilities to the basic photoionization detection

principles exhibited by the HNU PI 101. The microprocessor provides electronic zeroing, site and time data

logging, and the ability to store up to 12 calibrations. The unit provides two basic modes of operation, the

first being the survey mode and the second being the hazardous waste mode. Like the PI 101, the DL-101-2

is also factory calibrated using benzene as the reference standard. The primary method of calibration will

also use 100 ppm isobutylene in air (the calibration gas standard) with the unit in the survey mode.' If

several compounds are suspected, the hazardous waste mode may be utilized to store the needed amount of

calibration curves. In either case, it is essential to identify the lamp voltage being used and the

photoionization sensitivities of the chemical species of interest.

To calibrate irt the survey mode, follow these instructions:

1. Identify the lamp energy. If this information is not available on the outside of the probe,disassemble the probe and inspect the lamp. The energy of .the lamp should be etched into theglass envelope.

2. Press the power button to start the unit. Wait one minute to allow the unit to warm up,

3, Fill a dedicated tedlar bag completely with isobutylene calibration standard.

4. Press the CALIBRATE key on the front panel. "Calibrate" should appear on the liquid crystaldisplay (LCD).

5. Press ENTER. "Zeroing Unit" will appear on the LCD. The unit will display the unitconcentration before the electronic zero. The display will then prompt: CE/ENT/EXIt Cone =__ppm. Enter the concentration of the calibration gas and press, enter. "Attach gas to probeand /ENTER/" should appear on the LCD.

6, Attach the tedlar bag to the probe "and press ENTER. Allow the sample to be naturally drawninto the unit. Press ENTER when ready, "xxxxppm" should appear on the LCD. When thereadings reach 100 ppm (± 10 percent), press ENTER. The LCD should then display"Calibrating., .please wait."

E-3

AR308I73

In the survey mode, the unit will save the calibration and then the LCD reverts to the operation

screen. When additional calibrations are called for, utilize the hazardous waste mode and cross reference

calibration responses with the DL-101-2 user's manual. .

Organic Vapor Analyzer Foxboro Model 128 , . . . . . . . . -,, -

Theory of Operation . ' ...

The Foxboro Model 128 organic vapor analyzer (OVA) is designed to detect and measure hazardous

vapors and gases. The instrument utilizes the principle of hydrogen flame ionization for detection and

measurement of organic vapors. The mstrument' measures organic vapor concentration by producing a

response to an unknown/sample, which can. be related to a gas of known composition to which the

instrument has been previously calibrated. During normal survey mode operation, a continuous sample is

drawn into the probe and transported to the detector chamber by an internal pumping system.

The sample stream is metered and passed through_particulate filters before reaching the detector

chamber. Inside the detector chamber, the sample is exposed to a hydrogen flame that ionizes the organic

vapors. When most organic vapors burn, they leave positively charged carbon-containing ions. An electric

field drives the ions to a collecting electrode. As the positive ions are collected, a current corresponding to

the collection rate Is generated. This current is measured with a linear electrometer preamplifier that has an

output signal proportional to the ionization current. A signal conditioning amplifier is used to amplify the

signal from the preamp and to condition for display on the probe/readout assembly.

The OVA will primarily be used in the survey mode. In the survey mode, the OVA is internally

calibrated to methane by the manufacturer. When the instrument is adjusted to manufacturer's instructions,

it indicates the true concentration of methane in air.. In response to all other detectable compounds,

however, the instrument reading may be higher or lower than the true concentration.

The following procedures detail the operation, calibration, hydrogen refilling, and recharging methods

EO be used with the OVA:

1. The instrument is now calibrated for methane and ready for service.

If the flame-out alarm is actuated, check that the pump is running, then press the IGNITERbutton. Under normal conditions, flame-out results from sampling a gas" mixture that is above thelower explosive level, which causes the hydrogen flame to extinguish. If this is the case, reignitionis all that is required to resume monitoring. Another possible cause for flame-out is restriction ofthe sample flow line, which would not allow sufficient air into the chamber to support combustion.The normal cause for such restriction is a clogged panicle filter.

It should be noted that the chamber exhaust port is on the bottom of the case and blocking thispon with the hand will cause fluctuations arid/or flame-out,

SAMPLING PUMPS (SKC.JMSA. or Gillian) - - - ' - ——

Sampling pumps utilized to collect personal and area samples will be calibrated before and after

sampling. In each case, the sampling pumps will be calibrated in accordance with parameters established in

National Institute of Occupational Safety and Health (NIOSH) Manual of Analytical Methods (1984).

Calibration will be performed onsite using a primary standard (i.e., electronic bubble meter or 1-liter glass.

buret). Calibrations of sampling trains will be conducted with the collection media (i.e., charcoal tubes,

XAD-2 tubes, tenax, cyclone separators, impingers, etc.) in line with the primary standard to ensure quality

data.

The following calibration procedures should be followed when calibrating sampling trains:

1, Electronic Bubble Meter Method - - - ... -

a. Allow the pump to run five minutes before voltage check and calibration.

b. Connect the collection media to the bottom of the calibration meter by Tygon tubing. Thenconnect the pump and the tubing to be used to the top of the meter. This will allow thesampling train to be calibrated as it is to be used.

AR308-I80

2, Operation consists of using the pump to draw a known volume of air through a detector tubedesigned to measure the concentration of the substance of interest. The concentration isdetermined by a colorimetric change of an indicator that is present in the tube contents.

Applications/Limitations •-*•

I. Detector tubes/pumps can measure more than 200 organic and inorganic gases and vapors or forleak detection. Some aerosols can also be measured.

2, Detector tubes of a given brand are to be used only with a pump of the same brand. The tubesare calibrated specifically for the same brand of pump and may give erroneous results if used .witha pump of another brand,

3. A limitation of many detector tubes is the lack of specificity. Many indicators are not highlyselective and can cross-react with other compounds. Manufacturer's manuals describe the effectsof interfering contaminants.

2 4. Another important consideration is sampling time. Detector tubes give only an instantaneousinterpretation of environmental hazards. This may be beneficial in potentially dangeroussituations or when ceiling exposure determinations are sufficient. When, long-term assessment ofoccupational environments is necessary, short-term detector rufae measurements may not reflecttime-weighted average levels of the hazardous substances present.

5, Detector, tubes normally have a shelf-life at 25 degrees Celsius ( C) of one to two years.Refrigeration during storage lengthens the shelf-life. Outdated detector tubes (i.e..beyond theprinted expiration"date) should never be used.

Performance Data ., - - - • • , - . . . . - - — . - -

1. The specific tubes are designed ,to cover a concentration range that is near the PermissibleExposure Limit (PEL). Concentration ranges are tube-dependent and can be anywhere from oneone-hundredth to several thousand ppm. The limits of detection depend on the particulardetector tube.

2. Accuracy ranges vary with each detector tube (+ 25 percent).

3. The pump may be handled during operation (weighing from 8 to 11 ounces) or it may be anautomatic type (weighing about 4 pounds) that collects a sample using a preset number of pumpstrokes, A full pump stroke of either type of short-term pump has a volume of about 100 cubiccentimeters (cm).

4. In most cases where only one pump stroke is required, sampling time is about on minute.Determinations for which more pump strokes are required take proportionately longer.

Leakage Test _ .-,-,-.- - - - - - - - , - . = - • -

1. Each day before use, perform a pump leakage test by inserting an unopened detector tube intothe pump and attempt to draw in 100 ml of air. After a few minutes, check for pump leakage byexamining pump compression for bellows-type pumps or return to resting position for piston-typepumps. Automatic pumps should be tested according to the manufacturer's instructions.

1, In the event of leakage that cannot be repaired in the field, notify the DHSO to expedite repairs.

1. .Calibrate the detector tube for proper volume measurement at least quarterly.

'2. Simply connect the pump directly to the bubble meter with a detector tube in-line. Use adetector "tube and pump from the same manufacturer.

3. Wet the inside of the 100cm3 bubble meter with soap solution.

4. For volume calibration, experiment to "get the soap bubble even with the zero mark of the buret.

a. For piston-type pumps, pull the pump handle all the way out (full pump stroke) and notewhere the soap bubble stops; for bellows-type pumps, compress the bellows fully; forautomatic pumps, program the pump to take a full pump stroke. For either type pump, thebubble should stop" between the 95 cm3 and 105 cnr marks. Allow four minutes for the pumpto draw the full amount of air (This time interval varies with the type of detector tube beingused in-line with the calibration setup).

b. Also check the volume of 50 cm3 (1/2 pump stroke) and 25 cm3 (1/4 pump stroke) ifpertinent." As in Section 1 above, a ±5 percent error is permissible. If error is greater that±5 percent, send the pump for repair and recalibration.

5. Record the calibration info'rmation required on the Calibration Log.

6. It "may be necessary to clean or replace the rubber bung or tube holder if a large number of tubeshave been taken with the pump. - - -

Special Considerations . _ . . . . . . . . . .

I, Detector tubes should be refrigerated when not in use to prolong shelf life.

2, Detector tubes should not be used when cold. They should be kept at room temperature or in ashirt pocket for one hour before use.

COMBUSTIBLE GAS INDICATOR (Model 361 or equivalent) . . . . . . . .

Theory o f Operation .,__ . . . , . . _ _

The Model 361 Hydrogen Sulfide combustible gas and oxygen sensors operate simultaneously. Each

sensing circuit is equipped with an individual, visual alarm descriptor. There is a common, pulsating audible

alarm. One position "of'the FUNCTION switch enables the audible alarm to be turned off, if so desired.

The alarm descriptors will remain on until the concentration returns to within the alarm setpoints and the

reset button is depressed. -

A low-battery alarm will activate the BATT descriptor on the display and a continuous, steady-

sounding audible alarm. This steady sound indicates that the Model 361 must be removed from service and

charged in a nonhazardous area.

WARNING: Exposure of the combustible gas sensor to a concentration high enough tocause the readout to indicate a reading higher that 100' percent Lower Explosive Limit(LEL) will cause the readout to latch. When latched, the LEL readout will be blank andthe descriptors for OVER and LEL ALARM will appear. This latching circuit is awarning that the gas concentration has exceeded the LEL and that all personnel mustevacuate the area.

This latching circuit can be reset by removing the Model 361 to an area known to be free of

combustible gas (fresh air) and turning off the instrument. The Model 361 can then be turned on and

rezeroed in fresh air. This latch circuit does not "operate during the first 30 seconds after turning "on the

instrument, thus providing sufficient time for sensor warm-up and rezeroing.

Toxic Gas Sensor

E-13

AR308I83

The' toxic gas sensor" "used ih'the Model 361 is a membrane-sealed electrochemical cell. The cell

requires an external voltage source to function and produces a current output that is proportional to the

amount of H2S present. The H2S diffuses through the 'front membrane" of "the cell and is oxidized at the

working electrode. Current- flows through" the liquid'electrolyte "(acid solution) to the counter/reference

electrode where oxygen reduction occurs". .The amount of current produced for a concentration of H:S is

dependent on the voltage across: &e working reference electrodes. as .well as the electrode materials and the

electrolyte. The choice of the particular noble metal electrodes and the setting of the cell voltage optimizes

the sensor for the detection of H2S. ,

The current from the cell is fed to a current-to-voltage converter. This voltage signal is applied to an

amplifier that drives the toxic gas readout and provides and input for an alarm comparator circuit.

Combustible Gas Sensor L . .._.,._. , . . . . - . ' ' . . . ,..,. . . . - . . . . . .

The flammable, properties of combustible gases are used as the basis of detection. The sensor consists.

.of a pair of pelletized filaments "called Pelements™ arranged - in an electrically balanced bridge circuit. The

detector pelement is treated with a catalyst that causes the combustible gases to combine with oxygen at

much lower temperatures than would be required for normal burning. The inactive compensator pelement is

also exposed to the sample flow and acts to offset any electrical changes caused by flow conditions, sample

temperature, pressure,'and/or humidity.

. Combustible g'ase's m the sample combine with oxygen in the'air at the surface of the catalyzed

detector pelement. Heat is liberated by this chemical reaction, thus increasing the temperature of the

pelement and causing an associated, increase, in "the pelement electrical resistance.

Increased resistance of the detector pelement .unbalances the bridge circuit, causing a voltage change at

the mid-point connection between the detector pelement and the compensating pelement. This voltage signal

is applied to-an amplifier that drives the combustible gas readout and provides an input for an alarm

comparator circuit. = ~.". - ;—-- --.-..- .__.; • _- ;;-;; ;•- . . t.

1.0 INTRODUCTION

This Draft Field Sampling Plan (FSP) has been prepared by Harding Lawson Associates [HLA) onbehalf'of Bridgestpne/Firestone, Inc. (BFS). This FSP is submitted pursuant to the terms of theAdministrative Order on Consent (Order) for Remedial Design and Remedial Action (RD/RA) at theWoodlawn Landfill Site, Docket No. HI-QS-pS-pC, with an._effective date of December 27, 1994. TheRD/RA will be conducted to design and implement the most effective remedy for the Site.

This Draft PSP has been prepared in accordance with the Guidance for Conducting Remedial Designand Remedial Action Under CERCLA, (OSWER Directive _9355.0-4A [IQBQ]),A Compendium ofSuperfund Field Operations Methods (OSWER Directive 9355-0-14 [December 1987]), and EPANational Enforcement Investigation Center Policies and Procedures Manual (EPA 330/978-001 [May1978, revised November 1984]) and other documents listed in the bibliography section.

The Order addresses req Qirerrients associated with the development and submittal of a RemedialDesign Work Plan for the Site (RD Work Plan) which includes a Sampling and Analysis Plan (SAP) anda Health and Safety Plan (HASPJ7. The FSP and the Quality Assurance Project Plan (QAPP) comprisethe SAP. Information presented in this FSP includes sampling objectives, numbers and types ofsamples to be collected, sample locations, sampling procedures, and sample handling and analysis .protocols. The QAPP details quality assurance arid quality control (QA/QC) procedures associatedwith sampling and laboratory analysis, and data reporting.

The primary field activities to be conducted at this time are associated with the geological, engineering,and ecological pre-design studies. The field activities associated with the pre-design studies includewell and boring installation and grouiidwater, and surface-water, sediment, shallow groundwater, andsoil sampling tasks.

2.0 SUMMARY OF SITE CONDITIONS

2.1 Sit* Physical Characteristics

2.1.1 Location

The Woodlawn Landfill Site (Site) is located in a rural area approximately one half mile north of theTown of Woodlawn, and one mile north of the intersection of Routes 275 and 276 in Colora, CecilCounty, Maryland. Rural residences and undeveloped properties surround the Site in all directions (IT,1992).

2.1.2 Topography, Drainage, and Vegetation

The land surface In the north-central area of the Site slopes gently to the southwest from thetopographic high point near the northeast corner of the Site. The southwestern portion of the Site .__slopes steeply down to a swale and an unnamed stream. The maximum relief within one mile of theSite is approximately 200 feet (IT, 1992).

Tree cover at the Site Is most dense in the southern portion and at the perimeter of the landfillproperty. Grasses and shrubs cover the north-central portion of the Site where previous landfillingoperations reportedly took place.

In the south-central portion of the Site, there is a retention basin that was reportedly designed tocollect runoff from the landfill. A portion of the retention basin contains a palustrine emergentscrub/shrub wetland (EPA, 1993b). Some of the surface flow on the eastern side of the landfillproperty (near Cell B/C) is channeled south, then west, into the retention basin. When precipitation isheavy or of long duration, nmoff accumulates in the retention basin.. The basin discharges through acorrugated steel pipe into a manmade swale that extends.southwestward into the unnamed streamlocated near the southern tip of the Site.

Most runoff from the Site drains to the unnamed stream. The floodplain of the unnamed stream isoccupied by a palustrine broad-leaved deciduous forested wetland (EPA, 1993b).

The unnamed stream flows to the west-northwest and enters Basin Run Creek (a State-designatedtrout stream) approximately 1.5 miles from the Site. Basin Run Creek discharges into Qctoraro Creekapproximately 3.5 miles northwest of the Site. Octoraro" Creek flows westward until it joins theSusquehanna River, which flows into the Chesapeake Bay.

2.1.3 Geology

The Site is located in the Piedmont Plateau Physiographic Province approximately 5 miles west of theFall Line, which separates the Piedmont from the Atlantic Coastal Plain Physiographic Province. Thegeneralized geology of the Site area has been described in the Remedial Investigation (RI) as sand andgravel deposits overlying saprolite (decomposed bedrock) and the parent metamorphic bedrock.

. EPA Aujuit 31.1»SHarding Lawson Associates

AR3U8200

DRAFT

The Site stratigraphy from bottom to top can be generalized as follows:

• Bedrock of the Paleozoic Port Deposit Gneiss* Residual soils derived from in situ weathering of the bedrock (saprolite)• Continental Cretaceous Potomac Group (clay and sand)« Tertiary Upland Deposits (gravel and sand)• Holocene-age transported soils, including stream-derived sands and gravels (alluvium) and

soils washed from hills (colluvium)• Disturbed materials such as waste and reworked natural soils (fill)

Figure 2-1 in the RD. Work Plan is 'a geologic map of the Site area. Generalized geologic cross-sections(figures 2-2 through 2-6 in the RD. Work .Plan) were completed to illustrate this Site stratigraphy andfeatures. -. . . . . . . . -.......-.,....

The bedrock formations of the Piedmont Plateau are generally metamorphic and igneous. In thevicinity of the Site, bedrock is mapped as the paleozoic Port Deposit Gneiss (Maryland GeologicSurvey, 1968). The P_ort__Depbsit Gneiss is described as a strongly deformed intrusive complex ofgneissic diorite and biotite diorite; strongly foliated and sheared. According to the borehole lithologiclogs recorded during the RI, two bedrock.formations underlie the Site: a gneissic granite and ametadiorite. Based upon drilling logs from six borings near the, perimeter of the landfill, the gneissicgranite underlies the saprolite across much of the Site, except the extreme northwestern portion. Inthe northwestern portion of the Site, the uppermost bedrock unit is described as metadiorite. Thegneissic granite is.describecTin each of the remaining bedrock wells at the Site and appears to bethicker on the east-southeastern portion. The metadiorite" was encountered below the gneissic granitein the eastern portion of the Site. Two of the bedrock well boring logs indicate that the gneissicgranite and metadiorite are intertongued and are described as banded at depth. The gneissic granite isdescribed as pink and coarsely crystalline with weak foliation. The metadiorite is described as black,white, and finely crystalline with pronounced schistosity. Both the gneissic granite and themetadiorite contain interlocking crystals of feldspar, quartz, hornblende, mica, and other minerals.These minerals contain silica, iron, durninurn, manganese, calcium, sodium, potassium, and traceelements. Upon weathering, the gneissic granite and the metadiorite break down into clay minerals,silica, and oxides of iron and manganese. The iron and manganese oxides, become more soluble inoxygen-poor OT reducing environments and can be transported by the groundwater. This naturalsource may account for some of the iron and manganese in the groundwater at the Site (IT, 1992).

A thick layer.of residual decomposed bedrock (saprolite) overlies the bedrock, at. the Site. .Saprolite isdefined as a soft, clay-rich, thoroughly decomposed rock formed in place by the chemical weatheringof metamoTphic and igneous rocks (Bates and Jackson, 1984). Saprolite is characterized by thepreservation of structures that were present in the unweathered rock. The saprolite encountered inthe borings at the 'Site has, over time, been described as sand, silt, clayey silt, or decomposed rock onthe Site boring logs. The saprolite ranges in thickness from approximately 15 to 90 feet at the Site;The saprolite is thickest in the northern portion of the Site and thinnest in the southern portion of theSite.

DRAFT

According to Spotts, Stevens, and McCoy (1980), Cretaceous Age~F6tomac~Group sand and claydeposits lie above the saprolite in portions of the Site. Alluvium and colluvium also lie above thesaprolite in portions of the Site. Both the Potomac Group members and -the alluvium/colluviunicontain layers of sflly clay and clay in some areas of the Site.

Sand and gravel deposits on the topographic high at the Site have been described in various Sitereports as the Upland Gravel unit, the Upland Deposits, and the Bryn Mawr Gravel. According to theGeologic Map of Cecil County, Maryland (United States Geological Survey, 1986], the Miocene UplandGravel is a quartz gravel unit with scattered lenses of cross-stratified quartzose sand and local lenses,slabs, and balls of light gray clay. The upper portion of the Upland Gravel has been oxidized toreddish-brown. Quaternary alluvium also consists of sand, silt, clay, and gravel deposits.

During the time when the sand and gravel operation was in existence at the Site, portions of theUpland Deposits, the alluvium/colluvium, and possibly the Potomac Group sands were excavated andremoved from the Site. The fill at the Site consists of materials that may have been deposited intothese excavations, rearranged alluvium/colliivium, and mounds of reworked sand and gravel.

2.1.4 Hydrogoology

The saprolite and bedrock may be hydraulically connected in the area of the Site. The water tableacross most of the Site appears to occur within the saprolite. Near the southwestern corner of the Site(near monitoring well ITB-43, the unconsolidated material was unsaturated and groundwater wasencountered only in the bedrock.

Previous reports indicate a water table mound near the northeast corner of the Site. Groundwaterfrom this mound appears to flow radially outward. Because most of the monitoring wells onsite arescreened at varying depths, local groundwater flow directions cannot be readily established from theavailable data. Local groundwater flow directions are likely influenced by local topography, therelative permeabilities of the various units beneath the Site and sources of groundwater recharge. Theregional groundwater flow is toward the Susquehanna River and Chesapeake Bay, to the west-southwest,

There appears to be a perched water zone above the water table, which was intercepted in severalborings. Three wells, ITP-1, ITP-2, and ITP-3, were installed to investigate this unit. Because thesewells are oriented roughly in a straight line, information regarding groundwater movement in this zoneis limited.

Potable water at the Site and in the surrounding area is obtained from private wells. Most of thewells, Including the well that serves the transfer station (TSTA-1), reportedly tap fracture systems inthe bedrock water-bearing zone. Some potable water wells in the region, including the well on Parcel506 to the south of the landfill, may also tap groundwater in the unconsolidated material above thebedrock (IT, 1992, Section 2.1.2.2).

2.2 Groundwater Quality

Available data on groundwater quality include the following:

• Historical groundwater monitoring data collected prior to the RI (1978-1988) as presented inIT's computer database

« Groundwater monitoring data collected during the RI (1988-1992) as presented in FT'scomputer database . _

• Recent water level and chemical quality data collected during the HLA January 1995 samplingevent . •

The recent January 1995 data have not been fully evaluated.

The available monitoring data indicate, that several organic and inorganic compounds have beendetected in groundwater. The Record of Decision (ROD) establishes Groundwater Cleanup Levels forthe following constituents in the Site groundwater: 1,2-dichloroethane, tetrachloroethene,trichloroethene, vinyl chloride, benzo(a)anthracene,"benzo(a)pyrene, benzo(b)fluoranthene,benzo(k)fluoranthene, bis(2-ethylhexyl)phthalate, chrysene, pentachlorophenol, aldrin, alpha BHC,heptachlor, and arsenic. The ROD also establishes a procedure for determining Groundwater CleanupLevels for the following constituents: endosulfan I, arsenic; cadmium, manganese, mercury andvanadium. These constituents are presented with their cleanup levels in Tables 9 and 10 of the ROD(Appendix A of RD Work Plan)/

Preliminary review of the data, resulted in the qbs.ervations are discussed in Sections 2.2.1 and 2.2.2.Based on the observations, presented below and the current uncertainty in groundwater flow patternsat the Site, additional groundwater monitoring wells will be ins.talled and sampled during the pre-design investigations, as described in Section 4.2.3.3.6 of the RD Work Plan.

After preliminary evaluation of the historical analytical database, the chemicals selected in the ROD(as listed above) were organized into contaminants of primary and secondary concern with regard to.the remedial design. Contaminants of primary concern were those that were detected most frequentlyand/or will likely drive groundwater recovery and/or treatment technologies. Contaminants ofsecondary concern were those that were found only in a few wells or sporadically throughout the Siteand will likely not drive recovery and/or treatment technologies.

2.2.1 Constituents of Primary Concern

2.2.1.1 Vinyl Chloride

Vinyl chloride has been detected in samples from 28 of the landfill monitoring well locations. Vinylchloride has been detected consistently in wells in the vicinity of Cells A and B/C since 1981. Vinylchloride concentrations in 9 of the well locations generally increased from 1982 to 1986 and declined

relatively rapidly from 1987/1988 to the present. These conditions were observed in wells B-l/TTB-11,B-4, B-6, F-2, F-5, F-6, F-8, F-10, and OW-2. The general distribution of vinyl chloride in Sitegroundwater monitoring wells in November 1990 is shown in Figure 2-7 of the RD Work Plan.

Groundwater samples from well F-6 have historically exhibited the highest concentrations of vinylchloride at the Site. Vinyl chloride concentrations in samples from well F-6 rose to a maximum of1,176 /ig/L in 1987. Since that time, vinyl chloride concentrations in samples from this well havedeclined steadily. Historical vinyl chloride data for groundwater samples from many of the other wellsindicate the same trend. Chemical concentration data versus time graphs for wells F-2, F-5, F-6, F-8,F-10, and B-6 showing changes in vinyl chloride concentrations throughout the historical groundwatersampling are included in Appendix B of the RD Work Plan. These wells were selected as examplesbest illustrating this trend. The trend of decreasing concentrations of vinyl chloride with time wasalso observed in wells B-4, ITB-1 and OW-2. Data for 3 of the monitoring wells (F-3, F-7, and ITB-5)suggest possible increases of vinyl chloride concentrations with time. Historical vinyl chloride resultsfor these monitoring wells are discussed below.

Vinyl chloride concentrations reported in samples from well F-3 generally fluctuated between 1 /ig/L in1982 and 7 pg/L in 1990 with no consistent increase or decrease in concentration with time. However,the sample collected from this well in January 1995 contained 18 jtg/L vinyl chloride. This may be ananomaly or it may indicate a recent increase In vinyl chloride concentrations in groundwater in thisarea.

Vinyl chloride concentrations reported in samples from well F-7 generally increased from 17 jUg/L in1982 to 110 fj%/L In 1990, However, the sample collected from this well during the January 1995exhibited a vinyl chloride concentration of only 4 /ig/L [estimated).

Vinyl chloride concentrations reported in samples from well ITB-5 increased from 1 >g/L in March1990 to 15 g/L In January 1995. . . . .

Vinyl chloride concentrations in the remaining 16 wells showed no trends, had only a limited numberof detections, or were too close to the method detection limit to provide a meaningful interpretation ofthe data. These include wells B-2, B-5, F-4, F-9, F-ll, F-12, ITB-1, ITB-2, ITB-3, TTB-6, ITP-1, TTP-2,ITS-1, ITS-2, OW-1 and TSW-1.

2.2.1.5 Manganese

Manganese has been detected in Site groundwater since 19.82. It has been found in both the saproliteand bedrock wells, although at higher concentrations within the saprolite. Manganese was detected inbedrock wells at concentrations ranging from 1.5 to 15,800 g/L. Manganese was detected in saprolitewells at concentrations ranging from 1 to 24,200 g/L. The highest concentration of manganese in Sitegroundwater was detected in well F-7 at 24,200 / g/L in 1990. In general, manganese concentrationshave been consistently approximately two orders of magnitude higher in the eastern and southerngroundwater .monitoring wells than in those located in the northern and western portions of the Site.Manganese concentrations detected in the recent January 1995 ground water sampling event;appear tobe consistent with the previous data.

Of these wells, it assumed that up to 10 wells will be installed during Phase I of theinvestigation, and up to seven more may be installed at a later date. Potential locations of the wellsare illustrated in Figure 4-1. However, these locations may be modified in the field based oninformation developed from the soil baring program described in the previous section.

At each of the wells installed in the saprolite zone, a single sample will be collected from the screenedzone and analyzed for grain size and Total Organic Carbon (TOG) using ASTM methods D421/D422and EPA Method Lloyd Kahn, respectively. Geotechnical samples proposed for the pre-designinvestigation are summarized in Table 3. Monitoring well installation procedures are described inSection 6.7.

4.1.8.2 Aquifer Test Performance and Sampling

Step-drawdown tests will be performed to assess selected wells prior to the constant rate test. The.expected duration of the constant rate test is 48 to 72 hours, depending upon aquifer response. Thedesign and duration of the test will be determined after installation of the new monitoring wellsplanned for the pre-design investigation. If the optimum pumping rate is less than 5 gpm, theconstant rate test will be conducted for 48 hours, if possible. The general procedures for performanceof the aquifer tests are presented in Section 6.10. . „ .

Groundwater samples may be collected for two purposes during the aquifer test: contaminantcharacterization (CLP methods) and characterization to determine potential treatment processes (non-CLP methods). Analyses performed for contaminant characterization would include low-level TCLVOCs and Semivolatile Organic Compounds (SVOCs). If pesticides are detected in baselinegroundwater samples obtained near the proposed pumping well, TCL pesticides will be analyzedduring the aquifer test as welL Analyses for determination of potential treatment processes wouldinclude parameters which will provide data for developing a conceptual treatment process train.Ancillary, or pre-treatment processes, may need to be included to overcome some of the water qualitycharacteristics. Typical pre-treatment processes included filtering, clarification, softening, and pHadjustment. Conventional pollutants must be characterized to determine if treatment for otherpollutants is required. In some cases, it may be necessary to pretreat conventional pollutants prior tounits designed for VOC and SVOC contaminant removals. Specific analyses included in the sampling,analytical methods, and data types are listed in Table 1......... -. ^_- _-, - -

Prior to start-up of the step-drawdown test and the constant rate test, a sample will be collected foranalysis of vinyl chloride by Method 8010 with 24-hour turnaround time. The frequency at whichsamples will be collected during the aquifer test will be proposed in the Technical Memorandumissued after Installation of the Phase I monitoring wel}s.

If onsite treatment of aquifer test discharge is performed, samples may be collected at intervalsrecommended in the Phase I Hydrogeological Technical Memorandum at the following locationsduring the pumping phase of the constant-rate test:

• Collect samples at the extraction line discharge, prior to the treatment units for: the aquifertest discharge parameters, the metals treatability testing parameters and the aquifer testtreatment characterization parameters.

• Collect samples, from the air stripper effluent (liquid phase) and analyze for the air strippereffluent parameters.

• Collect samples from the air stripper emissions (vapor phase) and analyze for the air stripperemissions parameters.

• Collect samples from the carbon unit effluent and analyze for the aquifer test'treatmentcharacterization parameters.

The analyses may be modified, based on conditions encountered in the field and will be reduced ifonsite treatment is not performed.

4.2.1 Drain Field Relocation Evaluation

If required, an anticipated two percolation tests will be conducted in the area or areas evaluated forrelocation of the drain field. Preliminary areas proposed for the drain field relocation study are shownon Figure 4-4 of the RD Work Plan. A soil profile boring will also be installed in the vicinity of theareas proposed for drain field relocation. The boring will be installed to a depth of approximatelyeight feet. Test and boring locations will be determined during the evaluation of the .existing drainfield.The location and number of tests may be modified in the field, based on observed conditions.Procedures for percolation testing are described in Section 6.14, and those for test boring installationare described in Section 6.3.

4.2.2 Material Source Sampling and Evaluation

Two offsite sources may be evaluated for landfill clay cover material, and, if adequate general fillmaterial is not available onsite, two offsite borrow material sources may be evaluated. Two offsitematerial sources may also be evaluated as possible suppliers of drainage layer material. Samples ofpotential vegetative layer materials will also be obtained and evaluated. HLA proposes that thisevaluation be performed by Remedial Action Contractor prior to delivery of material for the vegetativelayer since the availability of potential sources is highly variable.

Soil that meets the initial screening criteria, as determined by the EPA in consultation with MDE, willbe further tested to evaluate their suitability for use as cover.

The laboratory screening for clay cover construction may include collection and analysis of 6 samples(3 from each source) for the following properties:

5.0 SAMPLE NOMENCLATURE

5.1 Numbering of New Monitoring Wells

Monitoring wells installed during the predesign investigations will be given the designation "MW-", andnumbered sequentially beginning with MW-101. hi areas where well clusters are installed, the •shallower well will be assigned an "A" suffix after the number, e.g., MW-101 A, and the deeper wellwill be assigned a "B" suffix. .._,,_'.. . ..„.. ' . ' - ' _ _ . - . . - . .... ,.

The existing monitoring wells were.inslalled over several years by several different entities. Therefore,the numbering of the wells is not consistent, e.g., OW-, F-, ITB-. Since the existing database ofanalytical results references these well numbers,, new'numbers will not be assigned to the existingwells. . , _ . . . . - , - -..-...... ...._-,-,._-..,,.._.. - . . , - -

5.2 Investigative Samples

Field personnel are responsible for uniquely identifying and labeling all samples collected during fieldinvestigation. All labeling will be completed in indelible ink and be securely affixed to the samplecontainer. An example of a sample label is shown in Figure 5-1. Sample labels will contain thefollowing information: ... " - ". ".","_ :" .. ". .'......7_ ~~.~. . . . .

• A project number and Site name• A unique sample identification number• The sample location• A sample description (soil or groundwater)• The sample status (grab or composite)• Chemical analysis parameters (analyte and EPA method number)• The sampling date and time ; . " . . . .• ' Initials of sampling technician .. _ _ . . . _ _ . __.. .__.• The chemicals used for sample preservation• Any useful remarks for the laboratory . _ .

A standardized nomenclature will be used for all samples collected, and each sample will be assigneda unique name. Groundwater samples will be designated by the name of the well from which theyare collected and the date on which they are collected. For example a sample collected from existingwell ITB-5 on March 1, 1095, wouldbe designated ITB-5/03-01-95. Similarly, a sample collected fromnewly installed moniidrihg well MW-101 on that date would be designated MW-101/03-01-95, and asample collected from well OW-1 would be designated OW-1/03-01-95. Although this system is notideal because of the wide variation in the protocols used to name the previously installed wells, it willbe use.d to maintain, to the extent possible, consistency between future data and that from previouslycollected samples. . - . . , . . - - • -

Samples from other media will be. designated by an abbreviation indicating the media sampled,followed by a numeric sample location designation and the date. If appropriate, the sample depthmay be included prior to the date.' Media abbreviations will be as follows:"
