Water Quality Monitoring Report <br /> Forward Landfill <br /> Non-Statistical Data Analysis <br /> During the third quarter 2015 monitoring period, the CNSDAM was performed for VOCs <br /> detected in the DMP wells. As shown in Table 3-1, non-statistical indications of a <br /> release were identified at well AMW-6 as a result of a quantifiable concentration of <br /> tetrachloroethene (PCE), and trace-level concentrations of trichloroethene (TCE) and <br /> dichlorodifluoromethane (DCDFM). Forward had previously requested that well AMW-6 <br /> be reclassified as a CAP well, since similar concentrations have been historically <br /> measured in this well. There were no other VOCs detected in DMP wells for the Austin <br /> Unit. <br /> Concentration Limit Thresholds <br /> In accordance with RWQCB Order No. 115-2014-0006, the routine inorganic monitoring <br /> data obtained from the Austin Unit DMP wells during the third quarter 2015 monitoring <br /> period were compared to intrawell concentration limits (CLs) established for each well. <br /> Details on the statistical analysis for the established CLs are presented in Appendix G of <br /> the fourth quarter 2014 Water Quality Monitoring Report for the Forward Landfill (GLA, <br /> 2014. As summarized in Table 3-3, the following CLs were exceeded during the third <br /> quarter 2015 monitoring period. <br /> • AMW-6—bicarbonate alkalinity, calcium, magnesium, potassium, and strontium <br /> Retesting will not be performed for well AMW-6 since this well is a CAP well, mis- <br /> identified in the most recent WDR. <br /> 3.1.5 Corrective Action/Evaluation Program <br /> Field and laboratory results for CAP and EMP wells for the third quarter 2015 monitoring <br /> period are summarized in Table 3-2. As shown in Table 3-2, 15 of 28 CAP/EMP wells <br /> reported one or more VOCs exceeding a Practical Quantitation Limit (PQL), with CAP <br /> well AMW-1 having the greatest number of VOCs (15) including 11 measured above a <br /> PQL. An annual report discussing the CAP and EMP monitoring results for the Austin <br /> Unit was prepared by Herst & Associates (Herst, 2015) and provided under separate <br /> cover. <br /> 3.1.6 Cannery Waste Land Application Monitoring <br /> Field and laboratory results for CWLAM wells for the third quarter 2015 monitoring <br /> period are summarized in Table 3-4 and were compared to Water Quality Protection <br /> Standards (WQPS) calculated for CWLAM constituents (total nitrogen, arsenic, iron, and <br /> manganese). As shown on 3-4, no WQPS were exceeded during the third quarter 2015 <br /> monitoring period. <br /> M:\2015.0014\FA 3Q15.docx 11 <br />
