1.0 INTRODUCTION

This report, prepared by Conestoga-Rovers & Associates(CRA), the Supervising Contractor, on behalf of the City of Charles City (City)and Solvay Animal Health, Inc. (SAH), presents a summary of the thirdquarterly groundwater monitoring activities completed under theGroundwater Monitoring Program (GMP). The GMP was submitted as anappendix to and forms part of the Remedial Action Plan for Operable Unit 1(OU1) at the Shaw Avenue Site.

2.0 SITE BACKGROUND

The Shaw Avenue Site (Site) is located along thesoutheast limit of the City of Charles City, Floyd County, Iowa. The Site issituated south of Clark Street, approximately 500 feet east and 200 feet north ofthe Cedar River. The Site is owned by the City of Charles City. The City ofCharles City Wastewater Treatment Plant (WWTP) is located immediately tothe east of the Site.

On February 28,1992, the City and SAH entered into aConsent Decree (CD) with U.S. EPA Region VH for remediation of OU1.Consistent with the ROD and pursuant to the CD, the remedial action forOU1 consisted of excavation, off-site treatment and disposal of chemical filland excavation and off-site disposal of contaminated soil exhibitingconcentrations of arsenic or cadmium above the performance standards.

In April and May 1992, the remedial action for OU1 wascompleted. The chemical fill was treated prior to landfilling at a ChemicalWaste Management, Inc. (CWM) RCRA authorized landfill using BestPractical Means as determined from CWM treatability studies and theavailability of treatment facilities at the RCRA authorized CWM landfill. Thecontaminated soil was landfilled, without treatment, at a RCRA authorizedCWM landfill.

3.0 GROUNDWATER MONITORING PROGRAM

A total of 31 monitoring wells and three private wellsform the groundwater monitoring network. Figure 3.1 shows the location ofall monitoring wells.

From March 15, 1993 through March 19, 1993, CRAconducted the third post OU1 remediation quarterly groundwater qualitymonitoring event at the Site. Sample collection data sheets completed in thefield at the time of sampling and Chain-of-Custody Records are presented inAppendix A. Groundwater samples were collected pursuant to the protocolsdescribed in the GMP and were analyzed by Wadsworth/ALERT Laboratoriesof North Canton, Ohio.

The Wadsworth/ALERT laboratory reports have beenvalidated by CRA's quality assurance/quality control (QA/QC) officer basedupon a review of standard quality control criteria established in the analyticalmethods. The Data Quality Assessment and Validation report is presented inAppendix B.

4.0 POTENTIOMETRIC GROUNDWATER CONTOURS

Table 4.1 presents a summary of the post OU1 remediationpotentiometric groundwater elevations measured at the Site sinceSeptember 1992. Upper bedrock potentiometric groundwater contours, basedon potentiometric groundwater elevations measured at the Site during theMarch 1993 monitoring event, are shown on Figure 4.1.

As shown on Figure 4.1, groundwater flow in the upperbedrock is west to southwest towards the Cedar River, consistent with therepresentative upper bedrock groundwater flow patterns presented in theRI Report. The groundwater levels in all wells except at well MW8 compareto the previous second quarter levels measured during December 1992. Asnoted in the RI Report, a local perched alluvium aquifer continues to beobserved in the area of monitoring well nests MW8 and MW12. Also asnoted in the RI Report, bedrock well MW8 continues to exhibit an elevatedpotentiometric groundwater elevation above any other bedrock well in itsvicinity, including newly installed bedrock well MW19. As discussed in theRI Report, well MW8 does not specifically monitor the bedrock aquifer, butalso monitors groundwater recharge from the perched alluvium aquiferworking its way down through fractures in the rock towards the bedrockaquifer. The potentiometric data for well MW8, therefore, is not used to plotthe potentiometric contours of the upper bedrock aquifer, presented onFigure 4.1.


5.0 GROUNDWATER DATA SUMMARY

Table 5.1 summarizes the results of analyses for the threepost OU1 remediation quarterly groundwater quality monitoring events atthe Site. The third quarter groundwater quality is consistent with the firsttwo rounds with the exception of MW8. Figure 5.1 presents bedrockgroundwater arsenic concentration contours.

The highest concentrations of arsenic monitored duringthis and the two previous sampling events were measured in well MW8.MW8's groundwater arsenic concentrations increased to 9,960 ppb from5,880 ppb measured during the second quarter sampling and 5,300 ppb fromthe first quarter sampling. The RI Report previously noted theconcentrations of arsenic in well MW8 did not reflect bedrock groundwaterconcentrations because well MW8 does not specifically monitor the bedrockaquifer. Well MW8 is located immediately adjacent to the former chemicalfill and contaminated soil areas which were excavated in April and May 1992.Due to its proximity to these areas well MW8 continues to monitor acombination of leachate, which has migrated downward through the upperfractured bedrock, below the former chemical fill area, and groundwaterrecharge from the perched alluvium aquifer as it mixes with the bedrockgroundwater flow regime. The arsenic concentration measured in wellMW19, installed in 1992 immediately adjacent to MW8 to monitor bedrockwater quality in the area of the former chemical fill is approximately twoorders of magnitude (i.e. 100 times) lower than that measured in well MW8.

Additional quarterly sampling data for groundwater isrecommended to monitor the effectiveness of the OU1 remediation at theSite.

TO: Ed Roberts REFERENCE NO: 1585

FROM: Amber L. Poffenberger ^f DATE: May 3,1993

RE: Data Quality Assessment and Validation for ThreeSoil Samples Collected March 31, 1993 at the Solvay AnimalHealth Site in Charles City, Iowa

The following details a data quality assessment and validation for three soil samplescollected March 31,1993 at the Solvay Animal Health Site in Charles City, Iowa. Thesamples are identified in Table 1. Analytical parameters for the event are listed inTable 2. All analyses were performed by Enseco-Wads worth/Alert Laboratories(EWAL) of North Canton, Ohio. The quality assurance criteria was established bythe methods.1

Holding Time Periods

The holding time periods for the analyses are listed in Table 2. On the basis ofsample collection dates on the chain-of-custody forms and analytical reportsprovided by EWAL, the extractions and analyses were completed within thespecified holding time period.

Method Blank Samples

Contamination of the samples contributed by laboratory conditions or procedureswas monitored by the concurrent preparation and analysis of method blanksamples. Method blank samples for the analyses were reported to be free fromdetectable concentrations of target analytes, with the exception of silver, indicatingno significant laboratory contamination occurred. Silver was detected in themethod blank at 1.1 ug/L. Since silver was non-detect in the associated samples, noqualification of the data was deemed necessary.

Application of relevant quality assurance criteria was consistent with "National FunctionalGuidelines for Organic Data Review", December 1990 (Revised June 1991) and "Laboratory DataValidation Guidelines for Evaluating Inorganics Analysis", July 1988.

Reference No. 1585Page 2

Surrogate Compound Percent Recoveries

Individual sample performance for VOC and BNA analyses was monitored bysurrogate recoveries. The surrogate recoveries for the analyses were within theacceptance criteria for all samples.

Check Sample Percent Recoveries

Check samples were analyzed to assess the accuracy of the laboratory procedures.Percent recoveries for check samples were within the established control limits,indicating an adequate level of accuracy was achieved.

Matrix Spike/Matrix Spike Duplicate (MS/MSP) Results

To assess the long term accuracy and precision of the analytical method on variousmatrices, MS/MSD percent recoveries and the relative percent difference (RPD) ofthe recoveries were determined. The percent recovery and RPD data were withinacceptance criteria, indicating an adequate level of accuracy and precision wasachieved for the methods.

Field Quality Assurance/Quality Control (QA/QC)

The field QA/QC associated with this sampling and analysis event included one tripblank sample.

To evaluate the possibility of contamination arising from sample transport, theenvironment and/or storage, a trip blank sample was submitted to the laboratory forVOC analysis. The trip blank sample yielded non-detectable concentrations of targetanalytes, indicating no significant contamination occurred.

Overall Assessment

The data were found to exhibit acceptable levels of accuracy and precision and maybe used without qualification.
