Water Quality Monitoring Report Forward Landfill calculated for PCE at well AMW-12 (Table 2-S). Mann-Kendall trend analyses calculations are presented in Appendix G. 3.1.5 Corrective Action/Evaluation Program Field and laboratory results for CAP and EMP wells for the third quarter 2017 monitoring period are summarized in Table 3-2. Excluding suspected laboratory contaminants, 16 of 28 CAP/EMP wells reported one or more VOCs exceeding a practical quantitation limit (PQL), with CAP well AMW-22S having the highest total concentration of VOCs (53.20 µg/L). An annual report discussing the CAP and EMP monitoring results for the Austin Unit was prepared by Geo-Logic Associates (GLA, 2017) and reported under separate cover. 3.1.6 Cannery Waste Land Application Monitoring Field and laboratory results for CWLAM wells for the third quarter 2017 monitoring period are summarized in Table 3-4 and were compared to Water Quality Protection Standards (WQPS) calculated for CWLAM constituents (total nitrogen, arsenic, iron, and manganese). As shown in Table 3-4, WQPS were exceeded for iron and manganese in the sample collected from AMW- 10. In response, confirmation samples were collected on October 2, 2017. As shown in Table 3-4, the confirmation results did not exceed the WQPS for iron and manganese suggesting that the primary results were a false positive. 3.1.7 Domestic Well Monitoring Two domestic wells (8106-A and 7898-A) were sampled on October 4, 2017, and Table 3-5 summarizes the current analytical results for the domestic well samples collected. As shown in Table 3-5, PCE was measured above the PQL in both domestic well samples. In addition, DCDFM and TCE were measured at quantifiable concentrations in domestic well 8106-A and at estimated trace concentrations in domestic well 7898-A. Trace concentrations of 1,1-DCA and cis-1,2-DCE were also measured in the domestic well 8106-A. 3.1.8 Vadose Zone Monitoring The current vadose-zone monitoring network at the Austin Unit consists of 14 lysimeters (10 suction lysimeters and four pan lysimeters). The lysimeter locations are shown on Figure 3-1. As shown on Table 2-6A, all of the lysimeters were reported dry or had insufficient soil-pore liquid (<_ 10 milliliters) for analysis. 3.1.9 Leachate/Surface Impoundment Monitoring For the Austin Unit, leachate sumps and surface impoundments are inspected weekly by Forward Landfill personnel. If leachate is detected in a sump, it is pumped into the surface impoundment WMU F (West) for evaporation. During the third quarter 2017, leachate was Project No.5017.1030 I Water Quality Monitoring Report 12 October 2017
