The percentage of each analyte meeting WQPS and the percentage of analytes per well meeting the newly adopted WQPS were calculated (Table 2 following text). Results of the evaluations are presented on Figures 3 through 5 and the individual COCs discussed below. Semiperched and upper aquifer water quality meets 100 percent of WQPS in wells adjacent to the Stanislaus River in the southeast corner of the site(Figures 3 and 4). Intermediate aquifer water-quality analyses indicate that exceedances of the WQPS have occurred in all wells; however, the most compliant well(PW- 6) also is located in the southeast corner of the site adjacent to the Stanislaus River(Figure 5). pH All monitoring and production wells meet WQPS for pH.
