RE: REDUCED PARAMETER LIST TECHNICAL MEMORANDUMYEOMAN CREEK AND EDWARDS' FIELD LANDFILLS RVFS

Dear Mr. Boice and Mr. Nussbaum:

Enclosed please find the Reduced Parameter List Technical Memorandum for the YeomanCreek and Edwards' Field Landfills RVFS. We recognize that U.S. EPA/IEPA will requirea review period for a complete analysis of the requests made regarding parameterreductions. However, in order to facilitate the second round of groundwater samplingwhich is planned to start this week. Colder Associates requests that the U.S. EPA/IEPAprovide an expedited response for at least hexavalent chromium, BOD, and field turbidity.

Alternatively, if EPA requires more time to review this submission, the PRP committee isprepared to delay the sampling. However, we would prefer that any delay be short sincewinter is approaching.

If you have any questions or require further information, please contact us.

Sincerely,

1.0 INTRODUCTION

The approved RI/FS Work Plan for the Yeoman Creek and Edwards' Field Landfills

specifies that a technical memorandum will be submitted to the Agencies presentingrecommendations for reducing the analytical parameter list for the second and thirdrounds of groundwater sampling based on the results for the first round. The complete

set of analytical results has been received for the first round of groundwater samplingand also for the leachate wells. The data are presented in Tables 1 to 5. Validation ofthese data is currently in progress but will not be complete before the second round of

sampling must commence. Nevertheless, the unvalidated data are suitable for preparingrecommendations concerning reductions in the parameter list. In fact, validation will

probably strengthen the arguments for elimination of some parameters because validation

typically removes or reduces outliers.

Based on review of the first round of data for the groundwater wells and the leachate

wells, recommendations for reductions in the list of parameters for the second and thirdrounds of groundwater sampling have been prepared. The individual parameters or

groups of parameters that are planned to be eliminated are identified in the followingsection. The rationale for recommending elimination of each identified parameter or

group of parameters is also presented. In addition, two other issues related to the secondand third sampling events are discussed in the summary.

2.0 RECOMMENDATIONS FOR ELIMINATION OF PARAMETERS

2.1 Or panics

2.1.1 Pesticides/PCBs

Elimination of Pesticides/PCBs from the analytical parameter list is recommended becausenone of these compounds was detected in any of the groundwater monitoring wellsduring the first round of sampling. In particular, the shallow wells that are immediatelydowngradient from the landfills (e.g., east of the Yeoman Creek and Edwards' FieldLandfills) did not show any of the target Pesticide/PCB compounds, indicating thatmigration of these compounds in groundwater is not occurring. This conclusion is

strengthened further by the fact that the samples analyzed were unfiltered and containedparticulate material (see TSS results). Pesticides and PCBs generally partition strongly onto solids and desorb slowly. Consequently, if pesticides or PCBs are present in a

groundwater system, samples that include participates will show concentrations that aremuch higher than the actual dissolved concentrations. Dissolved concentrations are ofprimary interest with respect to evaluating migration. The absence of Pesticides and PCBs

in samples that contain particulates, therefore, indicates that these compounds are not

currently present and also, since desorption is slow, have not been present in the past.

The absence of Pesticides and PCBs in the groundwater wells is not surprising since thesecompounds were generally not reported in the leachate samples. Only one PCB

congener, a roc lor 1242, was detected in some of the leachate well samples, and it was

present at low concentrations (less than 190 n%/L). These reported leachate concentrations

are also for unfiltered samples and, therefore, the dissolved concentrations should bemuch lower. Again, the dissolved concentrations are of primary interest with respect toevaluating migration.

2.2 Metals and Cvanide

Some metals and cyanide were either not detected in the groundwater and leachatesamples or were only reported in a few samples with qualifications or at concentrationsbelow the preliminary levels of concern indicated in the approved RVFS Work Plan. As

October 1992 -3- 913-8083.227/913-8084.227

a result, several of the metals and cyanide are recommended for elimination from the

analytical parameter list for the second and third rounds of groundwater sampling.

2.2.1 Antimony

Antimony was not detected in any of the leachate well samples. Detection of antimonywas only reported in two filtered groundwater samples, but no antimony was detected

in either associated unfiltered sample. In addition, both detections of antimony in thegroundwater samples were qualified because antimony was detected in the correspondingblanks. Based on these results, the reported detections are not likely valid. Due to theprobable absence of this metal in all the groundwaters and, especially, the lack of

detections in leachate (Le., source), antimony is recommended for elimination from theparameter list.

2.2.2 Mercury

Mercury is recommended for elimination from the parameter list because it was notdetected in any of the groundwater samples and was only detected in some of the

leachate samples at concentrations below the preliminary level of concern.

2.2.3 Silver and Thallium

Silver and Thallium are recommended for elimination from the parameter list becausethey were not detected in any of the leachate or groundwater samples.

2.2.4 Cvanide

Cyanide was only detected in one leachate sample and one groundwater sample. In bothsamples, the concentrations were below the preliminary level of concern. In addition,

environmental air monitoring conducted at the site did not indicate the presence of

cyanide. Since cyanide is not a parameter of concern at the site, it is recommended thatit be eliminated from the parameter list

October 1992 -4- 913-8083,227/913-8084.227

2.3 Water Quality Parameters

2.3.1 Biological Oxygen Demand (BOD^

Both BOD and COD were measured in the groundwater and leachate samples. In all but

two samples, the COD was higher than the BOD, as would be expected. In the two

samples where the BOD value exceeded the COD, the COD was reported as not detected.It is likely that validation will revise these results. Several samples showed non-detectlevels of BOD but detectable COD suggesting that the COD is a better indicator of thepresence of organics. Based on the preponderance of the available data, the COD

appears to be a better and more sensitive indicator of overall organic content. For thisreason, BOD is recommended for elimination from the parameter list.

2.3.2 Chloride

Elimination of chloride is recommended because it is not a reliable indicator of possibleleachate contamination at this Site. Measured levels in the leachate wells were highlyvariable, ranging from 90 to 1280 mg/L. Concentrations in the groundwater monitoring

wells also ranged widely (from 7 to 1220 m^L), but one of the shallow background wellsshowed one of the highest levels (628 mg/L). These results indicate that high chloride

concentrations may occur that are not related to the landfills. A probable source for thehigh chloride concentrations is road salting in the winter.

2.3.3 Hexavalent Chromium

Elimination of hexavalent chromium is recommended because this species was not

detected in any of the groundwater or leachate wells. It is apparent from these resultsthat hexavalent chromium is not a parameter of concern.

2.3.4 Hardness

Hardness is a measure of the sum of the divalent cations, principally calcium and

magnesium, which are included on the TAL list. Since the principal TAL metals will

October 1992 -5- 913-8083.227/913-8084.227

continue to be analyzed, hardness data are unnecessary. Hardness, therefore, is

recommended for elimination from the parameter list.

2.3.5 Nitrate plus Nitrite

The concentrations of nitrate plus nitrite in the background wells ranged up to 0.16 mg/L.This level is higher than any reported concentrations for the leachate wells and all but

one (GW105) of the other groundwater monitoring wells. The concentration of 1.65 m^L

in the GW105 monitoring well was far below the preliminary level of concern (10 mg/L).Since nitrate plus nitrite is not a potential parameter of concern, it is recommended for

elimination from the parameter list

2.3.6 Total Dissolved Solids (TDS1

As part of the field sampling protocol, the conductivity of the groundwater is measured.Since conductivity is proportional to the total dissolved solids level, the measurement of

both conductivity and TDS is not necessary. Since conductivity measurements will be

continued in the second and third sampling rounds, TDS is recommended for elimination

from the laboratory analytical parameter list

2.4 Field Parameters

2.4.1 Field Turbidity

During the first sampling round, field turbidity measurements were conducted ongroundwater extracted from the wells at the time of sampling. Since many of the wells

are screened in relatively fine grained units or across sections that contain interbedded

fine grained units, the extracted water is generally turbid. In nearly all groundwater wells

sampled, the level of turbidity is such that the range of the field turbidity meter is

exceeded. The measurement of turbidity in the field, therefore, is planned to be

eliminated during the subsequent sampling rounds because it does not contributed usefulinformation. Elimination of this measurement will not affect overall data interpretation

because all samples are analyzed for Total Suspended Solids (TSS) which is a betterindicator of the amount of particulate material present.

3.0 SUMMARY

Based on review of the analytical results for the first round of groundwater sampling andthe leachate well sampling, recommendations have been prepared for reducing the

parameter list for the second and third rounds of groundwater sampling. The parametersor groups of parameters that are recommended for elimination from the parameter listare:

Pesticides/PCBsAntimonyMercury

SilverThalliumCyanide

BODChloride

Hexavalent ChromiumHardness

Nitrate plus NitriteTDS

Field TurbidityIn addition to reducing the list of parameters for the second and third rounds ofgroundwater sampling, other changes are planned for these sampling events. During thefirst sampling event, both filtered and unfiltered samples were submitted for metals

analysis. According to the approved RI/FS Work Plan, the need for both samples wouldbe assessed after the first round. Comparison of the results for the filtered and unfilteredsamples indicates that there are measurable contributions from the particulates for many

of the metals. This was expected because the metals are present in natural soils. Therelative contribution varies from well to well depending upon the turbidity of the water.Since the contribution from particulates cannot be confidently quantified and the

particulate contributions do not indicate an effect from the landfill, and also becausedissolved levels are of more concern (dissolved concentrations are an indication of the

levels of the metals that may be transported), the results for the filtered samples are of

October 1992 -7- 913-8083.227/913-8084.227

primary interest. Consequently, only filtered samples are planned to be collected during

the second and third rounds of ground water sampling.

The results obtained for both of the bedrock wells do not indicate any possible effect fromthe landfill. Therefore, as indicated in the approved RI/FS work plan, these wells will notbe included in the second and third rounds of groundwater sampling.
