Table 1 provides a summary of the analytical results for the quarterly water quality monitoring, as well as the aiplicable NYSDOH Drinking Water Standards and the U.S. EPA clean-up requirement for Tetrachloroethene. As indicated by the laboratory analysis, the treatment system effluent ineets the NYSDOH drinking water standards and the USEPA clean-up level of less than one part per billion (ppb) (or non-detectable) for Tetrachloroethene and meets the levels of less than 100 parts per billion for Trihalomethanes.

Tetrachloroethene was detected in the raw water (untreated) sample, RW, at a concentration of 19ug/l (ppb), exceeding the NYSDOH drinking water standard for that compound.

No VOC's were detected in the treated (stripper number 2) water sample, STEFF.

Two VOC's, Dibromochloromethane and Bromodichloromethane were found in the distribution water sample, DIST, at concentrations of 7.0ppb and 2.5ppb respectively. These values are well below the NYSDOH drinking water standards.

One VOC, cis-1,2-Dichloroethene w7asfound in the monitoring well number 4, W4, at a concentration of 1.6ppb. This value is well below the NYSDOH drinking water standards.

No VOC's were detected in the monitoring well number 11, W11

Methylene Chloride was detected in the trip blank water sample, TB, at an estimated concentration of .6ppb. This result is less than the Practical Quantitation Limit and is clue to laboratory contamination.

Analytical results found in DUP, a duplicate sample of the Raw Water sample, RW, are similar.

Refer to Table 1 for a summary of the groundwater analysis results for volatile organic compounds (VOC's). Table 1reflects the detectable concentration values which have been qualified as a result of data validation. Refer to Appendix A for the data validation report which details the changes in the detectable concentration values discussed above.

The PCE concentration in the Influent (raw water)-hasdecreased over the last sampling event (see Figure 2). To date, the PCE level in the raw water samples is not of significant concern, since the treated water and distribution water samples continue to exhibit non- detectable or insignificant concentrations of PCE. However, changes in PCE levels will continue to be closely monitored. Table 1 - SUMMARY OF QUARTERLY ANALYTICAL RESULTS KATONAH MUNICIPAL WELL October 2005

4.0 FUTURE ACTIONS

Water quality monitoring will continue to be conducted quarterly at the treatment system influent, stripper number 2 effluent, and distribution entry point. Groundwater monitoring well samples will be collected bi-annually. EPM will communicate with the Town of Bedford Water Department to schedule a date when all the taps are available for sampling.

The next sampling event, the end of the fourth quarterly event for year fourteen, is tentatively scheduled for December 2005. APPENDIX A

U.S. Environmental Protection Agency (USEPA) National Functional Guidelines for Organic Data Review, 1999. INTRODUCTION

Data qualification provides guidance regarding data usability. As part of the environmental laboratory analytical reportirlg process under most environmental methods of analysis, the laboratory is required to append data qualifiers to reported analytical observations to account for minor, acceptable QC deficiencies that arise during the course of standard operations. As part of the analytical data validation process, additional data qualifiers may be applied. These qualifiers are applied for other QC deficiencies that impact data quality but that may not have been identified by the laboratory or that may not be part of the reporting requirement of the applied analytical method. In many cases, the laboratory may be compliant with the requirements of the applied analytical methods but may not be compliant with the data validation review protocols.

In general, the data qualifiers are intended to assist the data user with the overall data interpretation by serving as descriptive indicators of the data quality of the associated analytical observations. There are a number of other data qualifiers that describe the representativeness of the associated data and also serve to provide information about the quality of the associated control data.

U The analyte was analyzed for, but was not detected above the reported sample quantitation limit.

UJ The analyte was not detected above the reported sample quantitation limit. However, the reported quantitation limit is approximate and may or may not represent the actual limit of quantitation necessary to accurately and precisely measure the analyte in the sample.

J The analyte was positively identified; the associated numerical value is the approximate concentration of the analyte in the sample. When data are qualified as estimated (qualified "J"), there generally is no information on the quantitative impact on the associated result although there may be useful information on the direction of bias of the result

R The sample results are rejected due to serious deficiencies in the ability to analyze the sample and meet QC criteria. The presence or absence of the analyte cannot be confirmed. In some cases, sample data are qualified as unusable and rejected (qualified "R") due to major method non-compliance or extreme deficiencies in associated QC data. In these cases, there is no information as to the presence or absence of the rejected analyte in the affected sample. VALIDATION SUMMARY

The analytical data has been reviewed in accordance with the appropriate regulatory guidelines and/or associated analytical methodology. If required, the data has been qualified, negated, or rejected according to applicable validation protocols and professional judgment. The analytical validation was performed based upon the following parameters:

* Completeness of data package Blank Contamination * Hold Times * GUMS Performance Check (Tunivg) Summaries * System Monitoring Compound (Surrogate) Recoveries * Internal Standard Area Performance * Initial and Continuing Calibration Results Matrix Spike (MS) and Matrix Spike Duplicate (MSD) Summaries * Laboratory Control Sample * Target Compound Identification and Quantitation

* All criteria were met for this parameter

OVERALL DATA ASSESSMENT

The volatile organics data was validated for compliance with the requirements set forth in EPA Method 524.2 and as described by the Standard Operating Procedure for the Validation of Organic Data Acquired Using Method 524.2. Overall, the data quality is acceptable. The data validation review has identified aspects of the analytical data that require qualification. The laboratory analytical data contained herein are deemed usable and in compliance with the New York ASP B Deliverable Format requirements.

VOLATILE ORGANIC RESULTS

General Comments

Documentation as required by the project sample analyses was included in the data package. Additionally, there were no discrepancies found between the reviewed raw data and summary forms.

Based on review of the chain of custody, a transcription error was identified for the sample description of project sample 'DIST'. The laboratory has identified the sample as 'D-ST'. The sample description should be corrected to 'DIST' and initialedldated. No further action is required by the laboratory. Blank Contamination

Laboratory method blanks (instrument blanks) are clean liquid matrix samples prepared by the laboratory and analyzed in the same manner as the investigative samples. Laboratory method blanks are used to identify whether investigative samples have been contaminated during the sample preparation, sample analysis or from a previous sample (instrument carry-over).

Laboratory storage blanks (holding blanks) are clean liquid matrix samples prepared by the laboratory upon receipt of the investigative samples and stored with the samples under the same conditions. The storage blank is analyzed in the same manner as the investigative samples and is used to identify whether contamination may have occurred during storage of the samples in the laboratory.

Trip-blanks are carbon-free deionized water samples that accompany volatile investigative samples during all stages of shipment, storage and analysis. The trip-blanks are used to assess the potential for artificial introduction of volatile compounds into the investigative samples during the transportation and sample handling processes.

The VOA target compound, toluene, was detected in the method blank VBLKOl (0.4 pg/L) and VBLK02 (0.2 pg/L). Methylene chloride was detected in the field blank (0.6 pg/L) and trip blank sample (0.6 pg/L). The positive methylene chloride results in the associated project samples (RW, STEFF, DlST and DUP) are less than 10 times the concentration found in the trip and field blanks. Therefore the positive methylene chloride results for the associated samples are qualitatively questionable and negated due to laboratory and/or field contamination. No qualifier is required for toluene since it was not detected in the associated project samples.

The following table summarizes the compounds qualified due to blank contamination:

Sample Result Highest Blank Final Sample Sample ID VOACompound (tcgIL) Conc (pglL) Result (bglL) RW Methylene Chlor~de 0 5 J 0 6 0 5 U DlST Methylene Chlor~de 0 4 J 0 6 04U DUP Methylene Chlor~de 04 J 0 6 04U STEFF Methylene Chlor~de 0 4 J 0 6 04U

Hold Times

Technical hold times were assessed by comparing the sample dates with that of the preparation dates and/or analysis dates.

All volatile analyses performed on the associated project samples were within the required hold times. The sample cooler temperature (4.0°C) upon verified time of sample receipt (VTSR) in the laboratory fell within the 4OC (_+Z°C)requirement. Internal Standard Area Performance

Internal standards are analytes that are added to the investigative samples prior to analysis to ensure that GCIMS sensitivity and responses remain stable. Internal standards are reported with the volatile analyses.

The volatile internal standard area counts and retention times fell within control limits for the associated project samples. No qualifier is required.

Matrix SpikelMatrix Spike Duplicate

Matrix spikes are samples spiked with known concentrations of analytes of interest. The MSIMSD percent recoveries and duplicate results are used to assess extraction efficiencies, possible matrix effects, and overall analytical accuracy and precision.

A matrix spikelmatrix spike duplicate (MSIMSD) was performed on EPM Sample RW. The volatile percent recoveries (%R), for the most part, fell within control limits in both the MS and MSD samples. However, the MS recovery and RPD for target compound, tetrachloroethene, fell outside control limits (high). Therefore, the positive tetrachloroethene results in the associated project samples are regarded as estimated values and are flagged 'J".

The relative percent differences (RPD) of twelve target compounds fell outside control limits. No qualifier is required since this has minimal impact on the data usability.

Laboratory Control Sample

The laboratory control sample (LCS) andlor blank spike (BS) are blank samples fortified (spiked) with known concentrations of analytes of interest. The percent recoveries of the LCS andlor BS are used to assess overall analytical accuracy and precision.

The volatile LCS results fell within acceptable control limits. No qualifier is required.

System Monitoring Compounds (Surrogates)

System monitoring compounds are those compounds that are not expected to be detected in the investigative samples but that are chemically similar to analytes of interest. Surrogate compound percent recoveries are used to assess extraction efficiencies, possible matrix effects and overall analytical accuracy.

The recoveries of the volatile surrogates, 4-bromo.l:luorobenzene (BFB) and 1,2- dichlorobenzene-d4 (DCB), fell within control limits for the reviewed project samples.

Initial Calibration and Continuing Calibration Results

Control limits for initial and continuing instrument calibrations are established to ensure that the instrument is capable of producing accurate quantitative data at the beginning and throughout each of the analyses. The volatile initial and continuing calibration response factors (RRF), percent relative standard deviations (%RSD), percent differences (%D) and/or correlation coefficients fell within acceptable control limits. No qualifier is required.

GClMS Performance Check (Tuning) Summaries

Gas chromatograph/mass spectrometer (GUMS) instrument tuning and performance checks are performed to ensure the instrument's ability to provide appropriate mass-resolution, identification and sensitivity.

The bromofluorobenzene (BFB) tuning compound mass-ion abundance criteria for the volatile organic compound analyses were reported within control limits. The samples were analyzed within twelve hours of BFB injection. No qualifier is required.

Compound Identification and Quantitation

The laboratory calculations are verified and compound identifications are reviewed and assessed by the data reviewer.

In the course of the analytical procedures, it is sometimes necessary to dilute or reanalyze a sample. Frequently, the original analysis and dilution and/or reanalysis are reported by the laboratory and included in the report.

Sample DUP was collected and submitted as a blind field duplicate of project sample RW. The reproducibility of the associated analyses is good providing a positive indication of the accuracy and precision associated with these samples.
