' One (1) 100 mL sterile bottle preserved with sodium thiosulfate was collected from each well <br /> and was submitted to Far West Laboratories, Inc. in Riverbank, California (DHS#1310) for <br /> the following analyses: <br /> ' Total Coliform Bacteria <br /> • Fecal Coliform Bacteria <br /> ' Field measurements were recorded for the following parameters: <br /> • Groundwater Elevation (0.01 ft) <br /> • Temperature <br /> • pH <br /> • Electrical Conductivity (EC) <br /> ' Dissolved Oxygen (DO) <br /> 3.3 Groundwater Analytical Results <br /> ' The analytical results are summarized in Table 2 of Appendix A and briefly discussed below. <br /> A Site map with monitoring well locations is included as Figure 2. The laboratory analytical <br /> reports are included in Appendix B. <br /> The September 2015 groundwater analytical data are summarized as follows: <br /> ' • Generally the concentrations of the various groundwater analytes showed minor <br /> fluctuations this quarter with no significant increases or decreases occurring and the <br /> concentrations found are within the range observed thus far. <br /> TDS, FDS and VDS were reported to be within historical ranges for the WWTP, with <br /> the exception of TDS in well MW-7 which was reported to be a historical high <br /> ' concentration for this well. <br /> • Nitrate as Nitrogen was reported to be within historical ranges for the WWTP. <br /> • Sodium was reported to be within historical ranges for the WWTP, with the exception <br /> of MW-7. <br /> • Chloride was reported to be within historical ranges for the WWTP, with the <br /> ' exception of MW-7. <br /> • Biological Oxygen Demand was reported to be within historical ranges for the <br /> WWTP. <br /> ' Volatile Organic Compounds — were not reported above laboratory detection limits <br /> during the September 2015 monitoring event with the following exceptions: <br /> ' • MW-4 reported 0.31 µg/1 of chloroform <br /> MW-6 reported 0.58 µg/1 of chloroform <br /> MW-9 reported 1.1 µg/1 of chloroform <br /> ' • MW-10 reported 1.3 µg/1 of chloroform <br /> • Total Coliform Bacteria was reported to be non-detect above laboratory reporting <br /> limits in all wells during the September 2015 monitoring event, with the exception of <br /> ' MW-9. <br /> ' Ground Zero Analysis,Inc. 4 <br /> 894 P QMR 15 <br />
