Seven monitoring <br /> wells were sampled using the traditional purge method because the tethers with <br /> attached PDBs could not be lowered into the wells. Grab samples were collected <br /> from five extraction wells (E-2, E-6, EU-3, EU-4 and EW-1). Because the pump has <br /> been removed from extraction well EI-1, a PDB was deployed and sampled. <br /> 0o Samples from the City of Ripon wells and all private water supply wells were <br /> analyzed primarily for trichloroethylene (TCE), cis-1,2-dichloroethylene (cis- <br /> 1,2-DCE) and vinyl chloride (VC) using EPA Method 524.2 for drinking water. <br /> All other samples were analyzed for volatile organic compounds (VOCs) by <br /> United States Environmental Protection Agency (EPA) Method 82608. <br /> Tables 3.1 through 4 present the results of these analyses. <br /> 0o Ten domestic wells on the south side of the Stanislaus River were sampled <br /> monthly and analyzed for VOCs using EPA method 524.2. The analytical <br /> results were mailed to the well owners and to the RWQCB each month during <br /> this quarter. Table 5 presents these analysis results. <br /> 0o Table 8 summarizes the field parameters monitored during the sampling of <br /> each well. <br /> 3.1.3 Deviations from the MRP <br /> The MRP requires Nestle to submit quarterly reports, an annual report, and monthly <br /> performance monitoring reports for groundwater extraction and treatment systems. The <br /> groundwater monitoring program includes gauging groundwater elevations, collecting <br /> 4 <br />
