1, INTRODUCTION

Background -

Sampling of the ground water from the water supply wells located atHarrisburg International Airport indicates that the wells are contaminatedwith several volatile organic chemicals (VOCs). Currently, the U.S. Environ-mental Protection Agency (EPA) is considering setting maximum contaminantlevels {MCLs) for VOCs in drinking water. In November 1985, EPA establishedrecommended maximum contaminant levels (RMCLs) and proposed MCLs for eightVOCs in drinking water. The RMCLs and proposed MCLs for the eight VOCs are asfollows:

Established ProposedRMCL MCL

VOC _ (ug/L) (ug/L)

Trichloroethylene • 0 5Carbon Tetrachloride 0 5Vinyl Chloride 0 11,2-Dichloroethane 0 5Benzene 0 51,1-Dichloroethylene 7 71,1,1-Trichloroethane 200 200p-Dichlorobenzene 750 750

The RMCLs are nonenforceable health goals. Under the Safe Drinking Water

Act, setting RMCLs is the first step in setting standards. Under the law,recommended levels must be set at a point that presents no risk to publichealth. RMCLs of zero have been established for those five chemicals which

have sufficient evidence to be considered as probable carcinogens. The RMCLsfor the other three compounds have been set based upon their chronic toxicity.

The proposed MCLs will lead to enforceable standards. The MCLs havs been

set as close to the RMCLs as possible based on health considerations, treat-

ment technologies, and costs. Public comment on tetrachloroethylene, whichwas included in EPA's original RMCL proposal was extended in order to incor-porate new scientific data. The EPA will set the RMCL and propose an MCL forthis compound in the near future after public comments have been reviewed on

the new data. It is anticipated that the RMCL for tetrachloroethylene will beset at zero and the MCL will be set near 5 ug/L. RB30I273

In the absence of federal regulations, the Pennsylvania Department ofEnvironmental Resources (DER) has developed guidelines for VOC leveIs indrinking water. ..Guidelines for seven of the VOCs found in the HarrisburgAirport Wells have been"established:

VCX: —•— ~: ..- . Guide 1 ine (ug/L)

Purpose and Scope _ ___ _^As a result :of the VOCs being detected in the airport wells and the

current concern over these chemicals, Buchart-Horn, Inc. retained MalcolmPirnie to evaluate packed column aeration treatment for controlling VOCs inthe airport wells. Packed column aeration was selected because past inves-tigations have indicated that aeration is more cost effective than othertreatment techniques for/VOC removal. The purpose of this study is to developdesign criteria for the design of a full scale 'treatment facility utilizingexisting VOC treatability data from other contaminated sites where pilot

testing has been carried out.The scope of this s_tudy is limited to packed column aeration and in-

cludes: . •_.:: _: : : ..__ _ _ :_.1. Review existing well data and design criteria developed bŷ Buchart-

Horn.

2. Develop a process design and preliminary sizing of a packed columnaeration facility based on the performance criteria provided byBuchart-Horn. Estimate air emissions from such a system.

3. Prepare a report summarizing the process design criteria and providea description of a full scale treatment facility.

2. EXISTING WELL DATA

The individual well sampling data from the airport wells used in develop-ing performance criteria included in Appendix A, The data include samplingevents from March 1983 to June 1985 and indicate that the VOCs present areeither chlorinated hydrocarbon or aromatic solvents. The twelve VOCs whichhave been detected in the airport wells are listed in Table 1. The highestaverage concentration of each VOC over the sampling period is presented, alongwith the well in which that highest average concentration occurred.

As shown in Table 1, Well 13 is the most heavily contaminated, both in

terms of guantity and type of VOCs found. Well 13 is currently used to

mitigate the spread of VOCs and is pumped continuously. The treatment scen-

ario developed by Buchart-Horn for the packed column facility includes treat-ment of Well 13 along with other wells as make up.

concentrations were developed using the highest average levels detected in thegroup of wells plus an additional factor of safety. The actual influent VOCconcentrations will be lower than these design levels, since the actual flow

to the treatment system will be a composite of all the wells.The design effluent levels "were based upon DEE guidelines wherever

available. --In the absence of any guidelines, an effluent level of 2 ug/L was

used. -The performance criteria for each VOC are summarized in Table 2.TABLE 2

3. PROCESS DESIGN CONSIDERATIONS

Pilot scale packed column aeration data .from similar ground waters wereutilized as the basis for this design. The representative ground waters aresimilar in nature to the airport wells in terms of VOC type, VOC concentrationand water temperature. Experience with various ground waters indicate thatwaters with similar quality (i.e., similar VOC concentrations and water ._temperature) have similar VOC mass transfer characteristics. On this basis,the mass transfer coefficients were developed for the VOCs present in .theairport wells and used for design purposes. Also, an estimate of the VOC airemissions from a packed column is included in this section.

Mass Transfer RelationshipsVOC mass transfer relationships (the rate at which VOCs are removed from

water) were estimated for each of the VOCs found in the wells using data fromthe Malcolm Pirnie VOC treatability database. This database incorporatesMalcolm Pirnie pilot air stripping testing at over 30 different sites as well Ias USEPA pilot testing at 12 locations. Treatability information was not

available for chloromethane, vinyl chloride, and chlorobenzene. Mass transfercoefficients were generated empirically for these compounds frbm physical/

chemical properties and using a safety factor. The safety factor was estab-lished by comparing empirical mass transfer coefficients with actual masstransfer data developed from pilot testing.

The mass transfer' coefficients used in this analysis are presented inTable. 3. In general, as the mass transfer coefficient increases, the packingheight required to achieve a desired removal efficiency decreases. These

coefficients correspond to a liquid loading of 30 gpm/sf, which has been foundto be an effective liquid loading rate that results in an acceptable column

diameter and air pressure drop. Column diameters are sized such that theactual loading rate is less than or equal to 30 gpm/sf.

The mass transfer coefficient and liquid loading dete.rmine the height ofa transfer unit (HTU) for each VOC. The number of"~transfer units (NTU) to

effect a desired removal efficiency depends upon the removal required and the

58301277.__ _=. . -- *4*fl

3-1

stripping factor-.. :; The. .packing height required to achieve a desired removalefficiency "is then found by multiplying the HTU by the NTU.

Strippin g Factor _ . _ . : . .The stripping factor for a given VOC varies in direct proportion to the

air to water (A:W) ratio and the "Henry's Law'constant for that particular VOC.The A:W ratio is a function of .the water and air flowrates. The Henry's Lawconstants for each of the VOCs of concern are presented in Table 3. Henry'sLaw constants "give a relative indication of a compound's volatility, orability to be stripped. The lower the Henry's constant, the more air will berequired _to__strip the compound from solution to maintain a desired removalefficiency. _ _ " " . _ _ _ "

In general, it has been found that increasing the stripping factor beyondthe range of four to six- does hot significantly reduce the packing heightrequired to achieve a .desired removal, efficiency. Thus air to water ratiosused in this analysis have been selected to yield stripping factors of five orgreater for all the VOCs of concern.

Design CriteriaA spreadsheet computer program incorporating all the process design

calculations needed for sizing an air stripping column was utilized to facili-tate the development of design criteria. The mass transfer relationships andHenry's Law constants developed from the Malcolm Pirnie database were used asinput to the program, along with the removal requirements for each of theVOCs. Each VOC removal reguireme_nt was evaluated to determine the maximumrequired packing height. Chloromethane was found to be the VOC with thehighest required packing height which was 28 feet. Once this packing heightwas established, the removal efficiencies of the other VOCs at this packingheight were calculated and checked to insure that they met the performancerequirements. The computer output summarizing the expected performance of thepacked column for each of the VOCs at the design packing height of 28 feet isincluded in Appendix B. The output data indicate compliance with all of thetarget, levels. The design criteria for the packed column is summarized inTable 4. .... _. . .

4. RECOMMENDED FACILITIES

The previous sections of this report presented the existing well condi-tions and the process design criteria for packed column aeration treatment forcontrol of VOCs in the airport wells. Recommendations concerning facilitiesfor treating the airport wells to meet current DER guidelines and proposedfuture federal regulations for VOCs are outlined in this section.

Recommended ProcessThe results of the packed column aeration process analysis indicates that

this process is capable of achieving the high removal efficiencies which arerequired to reduce the VOCs in the airport wells to below current DER guide-lines and proposed future regulations. As indicated in the previous section,at the design influent levels the expected effluent VOC concentrations from apacked column designed to provide 99.1 percent removal -of-chloromethane shouldbe below the anticipated federal and state guidelines.

The recommended facility will fae designed to provide flexibility in theevent VOC levels should rise above the design influent levels or future

regulations require lower effluent levels than those which are being used fordesign purposes. This flexibility can be provided by using two packed col-

umns, each designed to provide -99,1 percent removal of chloromethane that canbe operated in either a parallel or series mode. A dual packed column treat-ment system will permit significantly higher VOC influent levels to be treated

and still meet the current effluent guidelines. A comparison of the allowableinfluent concentrations that could be treated by a single packed column or adual packed column system operated in parallel or series is presented in

Table 6. As indicated in Table 6, significantly higher allowable ,.influentconcentrations can be treated when the packed columns are operated in series.Parallel operation, while not providing as great an increase in allowable

influent concentration for the 12 VOCs of concern, will allow the treatment

system to be operated at a higher air to water ratio. The capability tooperate at higher air to water ratios will permit the treatment system toremove VOCs which are more difficult to strip than the 12 VOCs of concern,

should such compounds ever be detected in the airport wells. fiR^fl I 28

Recommended Treatment Facilities

A schematic diagram of the dual packed column system operating in seriesis shown on Figure 1. As shown, water from the airport wells would be pumped

up to the top of the first packed column and flow through the column into anintermediate clearwell from where it will be pumped to the top of the secondpacked column. Air will be blow up through the columns to provide a counter-current flow of water and air. Although not shown on this simple processschematic, the system will be designed to operate in either a series orparallel mode.

Each packed column and its internals will be constructed out of FRP. -Thepacking will be Jaeger Tri-Packs No.l (nominal 2 inch size) and be made out ofpolypropylene. Due to the large diameter of the column a weir and troughassembly similar to Jaeger FL-10-M "Weir Through" is recommended for liquid

distribution. Spray nozzles were considered but are not recommended due topotential plugging problems and poor turndown characteristics. Three inchesof a knitted wire mesh mist separator is recommended as a demister. Aninstalled spare blower will be provided for each packed column. The blowers

can either be fabricated out of metal or FRP and will not be housed. Acombination silencer and air filter will" be provided on the inlet to the

blowers.
