BACKGROUND

This report summarizes the results of semi-annual Groundwater and residential water well monitoring work completed by Viacom Inc. during the first half of 2003 at the Neal's Dump site.

Groundwater and residential water well monitoring was performed at a total of six locations (four monitor wells and two residential wells) in accordance with the April 1999 Post- Remediation Groundwater Monitoring Plan for this site.

2.0 GROUNDWATER AND RESIDENTIAL WATER WEEK MONITORING

Scope of Work

The scope of water sampling for this monitoring period comprised semi-annual sampling stipulated in the Post-Remediation Groundwater Monitoring Plan. The monitoring work described in this report was performed on March 20, 2003. Groundwater sampling was performed at the following locations:

• MW-1D
• MW-2D
• MW-3D
• MW-4D

Residential water well sampling was performed at the following locations:

• White residential well
• Eads residential well

Sample Collection and Handling

Samples at the monitoring well locations were collected using the dedicated bladder pump in each well. Prior to sample collection. the water level in each monitoring well was measured and the volume of water in well storage was calculated. Each well was then purged dry or until field parameters (temperature, pH and conductivity) stabilized to allow representative samples to be obtained. After field parameters stabilized, sample water was cc>~1 Ted in pre-cleaned amber glass 1-liter bottles supplied by the analytical laboratory.

Samples of both residential wells were collected at outside spigots by filling directly into pre- cleaned amber glass l-liter bottles supplied by the analytical laboratory.

Samples were analyzed by Heritage Lab of Indianapolis, Indiana. The samples were analyzed to a detection limit of 0.1 parts per billion (ppb) for all PCB parameters (except Aroclor 1221, which was to a detection limit of 0.2 ppb) by EPA SW-846 method 8082. Samples were also analyzed for total suspended solids (TSS) by EPA method 160.2.

Quality Assurance

For quality assurance purposes a duplicate sample and a field blank were collected during this sampling event. All environmental and blank samples were labeled and logged onto a chain-of- custody form. The samples were stored and transported on ice in insulated coolers. Custody of the water samples was maintained by Viacom until shipment to the analytical laboratory.

The field blank for this sampling event was ND10055. PCB results were BDL (below detection limit) for this field blank sample.

Analytical Results

Field parameter measurements, PCB analytical results, and QA/QC results for Groundwater samples collected during this reporting period are reported in Tables I through 4. Analytical results for samples from the White and Eads residential wells are presented in tables 5 and 6. respectively. Each table summarizes historical Groundwater monitoring data collected since the completion of the remedy in November 1998. Copies of the chain-of-custody forms are provided in Appendix A. Copies of the certificates of analysis are provided in Appendix B. A validation summary for these samples appears in Appendix C. Copies of the field sampling data sheets are on file at PSARA's Bloomington Branch Office.
