2.0 FIELD INVESTIGATIONS

2.1 General

A total of six soil test borings, designated B-l through B-fi were drilled by Briggs Associates, Inc. (BAI). Test borings B-l through B-3 were drilled on February 15, 1988 in conjunction with our Phase I-Site Assessment Report. Test borings B-4 through B-6 were drilled in conjunction with the current Phase II investigation. A groundwater observation well was installed in each completed borehole B-1 through B-6.

2.2 Test Borings

Subsurface conditions at the site were further explored by drilling three (3) additional test borings to a maximum depth of 15.0 feet (ft) below the existing ground surface. Test borings were drilled by BAI on May 16, 1988 under the full-time supervision of BAI personnel.

Subsurface explorations were conducted utilizing a SIMCO drill rig, driving 4-1/2 inch O.D.1 HW casing. Soil samples were obtained in accordance with ASTM D1586, "Penetration Test and Split Barrel Sampling of Soils". Standard Penetration Tests (SPT) were performed at depth intervals shown on the boring logs. Soil samples obtained from the test borings were classified by visual and textural examination in accordance with the Unified Soils Classification System. Test Boring Logs are included in Appendix A and the boring locations are shown on Figure 1.

2.3 Observation Well Installations

Following the completion of test borings B-4, B-5 and B-6, groundwater observation wells, OW-4, OW-5 and OW-6, respectively, were installed to monitor the groundwater level and to obtain water samples for selected laboratory analysis. Water level readings are shown on the boring logs. Refer-to Figure 2 for observation well locations.

Each well is constructed of a 0.01 inch slotted wellpoint section consisting of 2.0 inch I.D.2 polyvinyl chloride (PVC) threaded to a PVC riser pipe of the same diameter. Following the installation of the wellpoint and riser pipe, clean silica sand was employed as a filter pack around the wellpoint. A minimum one foot bentonite pellet seal was installed above the sand. The remaining annular space between the riser pipe and borehole wall was then backfilled with native sand. A gate box was concreted in place at the surface of each well installation to provide wellhead protection from vandalism and surface water infiltration. Groundwater Observation Well Installation Reports, with specific construction details for each well, are included in Appendix B to this report.

2.4 Ground Control Survey

BAI personnel conducted a limited ground control survey to establish water table elevations in observations wells OW-1 through OW-6 relative to an assumed benchmark of 100.00 feet at the top of the concrete loading dock bay. Refer to Table I for a summary of the survey data and Figure 2 - Groundwater Flow Conditions. fiure

Based on the survey data, site specific groundwater flow is in a general southerly direction Groundwater flow direction is subject to change with fluctuating groundwater levels and may be affected by local anomalous conditions and seasonal factors.

A teflon bailer was pre-cleaned prior to well purging using a four (4) step process: the bailer and teflon coated cord is washed in a soap solution, rinsed in tap water, rinsed in a 20% solution of methanol in distilled water, and finally rinsed in distilled water. The pre-cleaned bailer was carefully lowered to the water table and submerged one-half its total length. Upon removal no free-phase floating product was observed on the water surface in the bailer in any of the three fT

observation wells. K J

Prior to groundwater sample collection, the well was purged a minimum of three times the well-casing volume using a pre-cleaned teflon bailer. Samples for oil and grease analysis were stored in a pre-cleaned one liter clear glass bottle. Samples for volatile organic compound (VOC) analysis were stored in a pre-cleaned 40 ml glass vial with a teflon septum. Samples obtained for VOC analysis were carefully decanted from the bailer to minimize aeration. Samples for base neutral compound analysis were stored in a pre-cleaned one liter amber glass bottle. All water samples were packed on ice in an insulated cooler for transport to BAI's analytical laboratory. A chain of custody sheet was completed to account for sample handling.

No free floating product was noted during the sampling of OW-6, however, the bailer was stained with what appeared to be fuel oil, and a fuel oil odor was detected during the sampling operations Grab groundwater samples obtained from OW-4, OW-5 and OW-6 were analyzed for concentrations of VOCs via EPA Method 624/8240. Grab groundwater samples from OW-4 5 and 6 were analyzed for oil and grease concentrations via Standard Method 503A and 503E. Grab groundwater samples obtained from OW-4, 5 and 6 were composited in the laboratory and analyzed for concentrations of base neutral compounds via EPA Method 625. Laboratory results for groundwater analyses are summarized in Table 3, and the completed analytical laboratory reports are included in Apper.mx E. A comparison of water quality data for the February 22 1988 and May 27, 1988 samplings are summarized in Table 4. The completed analytical laboratory reports for analysis performed during the Phase I investigation are included in Appendix F.

3.3 Surface Water

Located along the southern boundary of the site is an intermittent stream. The water within this stream was sampled on May 27, 1988, along with observation wells OW-4, OW-5 and OW-6 Water quality samples were taken at three points along :he length of the stream bounded by the property. A slight sheen was noted on the water surface at the middle and downstream sampling locations. Samples 766ID and 766IE were respectively taken at the perceived upstream and downstream locations where the stream respectively entei s and exits the property. Sample 7661G was taken at a.point believec; to be the approximate middle of the stream, along the length of the property line near the locations of OW-3 and OW-6. No.e: During an inspection of the stream in August, the soils appeared moist, however :io water was observed.

Water quality samples 766 :D and 766IE were analyzed for concentrations of VOC's, while sample 7661G was analyzed for concentrations of oil and grease. Laboratory results for the surface water analyses are summarized in Table 3, and the completed analytical laboratory reports are included in Appendix E.

4.3 Recommendations <; i . *•

:• i '.'v

Based on the above data, there appears to be a decrease in VOC concentrations, as exhibited by the ? differing concentrations reported for sampling points OW-4, 5 and 6 from OW-1, 2 and 3, however, this decrease cannot be solely attributable to a decrease or elimination of the "source". The time lapse between Sample Set 1 (OW-1, 2, 3 sampled 2/22/88) and Sample Set 2 (OW-4, 5,.6 sampled 5/27/88) may be a contributing factor to the observed decrease along with the differing locations of the respective sampling points. To adequately address this concern and to provide a reliable water quality data base, BAI recommends the initiation of a quarterly monitoring program,' inclusive of synoptic water quality sampling to track the fluctuation of VOC concentrations versus time. This will enable the variation in groundwater conditions to be plotted on a time continuum which will provide the data needed for remediation design, if required.

Grab groundwater samples 7661A, B and C, from OW-1, 2 and 3 respectively, and grab surface water sample 7661G from the intermittent stream were analyzed for concentrations of oil and grease and the following concentrations reported 2 mg/L, 3 mg/L, 3 mg/L and 3 mg/jL, respectively. The above concentrations exceed drinking water limits of 0 ppm, however, aire within effluent limitations for Class I groundwater and surface water quality limits of 15 ppm (314 CMR 314 5.10 and 4.03). Although these concentrations are within the specified limits, experience has showed that a level of oil and grease above approximately 1.5 to 2.0 mg/L, coupled with the presence of certain VOC's, is indicative of petroleum compounds. !:' ||

¥ ?

Based on the above soil analytical data, the subsurface soils in the general area of sampling locations B-2, B-3 and B-6 and the underground storage tank (UST) contain significant concentrations of petroleum products. These concentrations may be the result of surface spillage of petroleum products or from subsurface migration of petroleum products from the UST. The TPH concentrations reported at sampling point B-2 are substantially greater than the TPH concentrations reported at sampling point B-3 and B-6, which are the sampling points nearestvtov 1 the UST. Location B-6 is the closest sampling point, however, the TPH concentrations are lowest. This may in part be the result of the composite nature of the sample. Generally the concentration of a single sample of a composite can be equated to the number of samples times the : reported concentration. Theiefore, the actual concentration of any one of the two samples in this composite can range from 600 mg/Kg to 1200 mg/Kg.

AMBIENT AIR PHOTOIONIZATION ANALYSIS , USING THE PHOTOVAC TIP II

SUMMARY OF SAMPLE PROCEDURE

i CALIBRATE THE, INSTRUMENT ACCORDING TO THE INSTRUCTIONS PROVIDED IN ' SECTION 4 OF THE TIP II USER'S MANUAL. RECORD CALIBRATION DATA AND

BACKGROUND LEVELS IN THE SPACES PROVIDED ON THE PHOTOIONIZATION DETECTOR FIELD DATA SHEET.

2. .{SAMPLE JAR HEADSPACE ANALYSIS

A FILL AN 8 OR 16-OUNCE GLASS JAR APPROXIMATELY ONE-HALF FULL WITH THE SOIL TO *' ' BE SCREENED. COVER WITH A DOUBLE ALUMINUM FOIL SEAL AND SCREW-ON CAP.

R SAMPLES SHOULD BE SCREENED AT ROOM TEMPERATURE. IN COLD WEATHER. WARM SAMPLES TO APPROXIMATELY 70 DEGREES FAHRENHEIT USING YOUR AUTOMOBILE HEATER OR BY PLACING. ON A WARM HOOD.

C SHAKE SAMPLE JAR VIGOROUSLY FOR APPROXIMATELY 10 SECONDS TO RELEASE

VOLATILE COMPOUNDS.

D REMOVE CAP FROM JAR AND PUNCTURE A SMALL HOLE IN THE ALUMINUM FOIL. INSERT THE TEFLON PROBE INTO THE HOLE AND RECORD THE HIGHEST READING FROM THE LCD

DISPLAY.

P ALLOW THE INSTRUMENT TO RETURN TO THE BACKGROUND READING. IF THIS TAKES TOO LONG ALLOW THE INSTRUMENT TO RETURN TO A READING LESS THAN 10 AND RECORD THE READING THIS READING IS THE NEW BACKGROUND LEVEL. ANALYZE THE NEXT SAMPLE AND SUBTRACTTHE NEW BACKGROUND LEVEL TO OBTAIN THE ACTUAL LEVEL OF

TOTAL IONIZABLE COMPOUNDS.

3. vlN-SITU SOIL HEADSPACE ANALYSIS ( I.e. PIT WALLS, BACKHOE

BUCKETS, ETC.)

A SCREEN SOILS WITH THE PHOTOIONIZATION DETECTOR IMMEDIATELY AFTER THEY ARE EXPOSED IN A TEST PIT OR TANK EXCAVATION. SCRAPE THE TOP FEW INCHES OF SOIL PRIOR TO SCREENING TO EXPOSE REPRESENTATIVE SOIL.

USING A STICK OR SIMILAR IMPLEMENT. POKE A HOLE 4 TO 6-INCHES DEEP IN THE SOIL TO BE SCREENED. REAM AND PACK THE HOLE USING A CIRCULAR MOTION.

C. IMMEDIATELY INSERT THE PROBE 2 TO 3-INCHES INTO THE HOLE. TAKING CARE NOT TO

ASPIRATE ANY SOIL

D. RECORD THE HIGHEST READING FROM THE LCD DISPLAY.

P ALLOW THE INSTRUMENT TO RETURN TO THE BACKGROUND READING. IF THIS TAKESTOO LONG. ALLOW THE INSTRUMENT TO RETURN TO A READING LESS THAN 1° AND RECORD THE READING THIS READING IS THE NEW BACKGROUND LEVEL. ANALYZE THE NEXT SAMPLE AND SUBTRACT THE NEW BACKGROUND LEVEL TO OBTAIN THE ACTUAL LEVEL OF

TOTAL IONIZABLE COMPOUNDS.

AMBIENT AIR PHOTOIONIZATION ANALYSIS USING THE PHOTO VAC TIP II

SUMMARY OF ANALYTICAL METHOD

The air samples were taken with a direct reading Photovac TIP II photoionization detector. Continuous sampling of ambient air, at a rate of approximately 275 ml/mm., is accomplished by a positive displacement pump. Detection occurs as the sample is drawn-through a high energy, ultraviolet Photoionization Detector YPID) to ionize a small portion of the introduced sample. The instrument is equipped with a lamp with an ionizing energy of 10.6 eV which will detect most oroanic compounds with an ionization potential of less than 10.6 eV The Drocess of ionization is initiated by the adsorption of a high energy photon by a molecule of the sample vapor in the ionization chamb- r. If the molecule's ionization potential is formed °r n the ph0t0n ener9y (hv)' a Positive ion and an electron is

R + hv + e"

Ion formation occurs in the electrical field etween the collector electrode and the jet in ihe ionization chamber of the deie< or. Ions and electrons that reach the e ec rodes contribute to a small ionizat. n current that is measured wlfh the electrometer of the instrument.

The amount of ions that reach, the el< ctrode will be proportional to the concentration of the lonizable molecules w chin the linear range of the detector The detector response is displayed on the digital readout with a range of 0-2000 ppm and a resolution of 0.1 parts per million. Using a 10.6 eV lamp, the range of detectable compounds encompasses a very large number of solvent materials and some important pollutant species including benzene, vinyl chloride

LTd tolufney " m'Xy,ene' aCet0ne' 1.2-dichlorobenzene, methyl ethyl ketone

Sampling environmental air can be accomplished with the Photovac TIP II by (1) headspace analysis of sample containers/or (2) analysis of ambient air near the target media.
