Water Quality Monitoring Report <br />Forward Landfill <br />101 <br />Field and laboratory results for CAP and EMP wells for the first quarter 2016 monitoring <br />period are summarized in Table 3-2. As shown in Table 3-2, 17 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 (14) including seven measured above <br />a PQL. An annual report discussing the CAP and EMP monitoring results for the Austin <br />Unit was prepared by Herst & Associates (Herst, 2015) and reported under separate <br />cover. <br />3.1.6 Cannery Waste Land Application Monitoring <br />Field and laboratory results for the four CWLAM wells for the first quarter 2016 <br />monitoring period are summarized in Table 3-4 and were compared to Water Quality <br />Protection Standards (WQPS) calculated for CWLAM constituents (total nitrogen, arsenic, <br />iron, and manganese). As shown on 3-4, no WQPS were exceeded during the first <br />quarter 2016 monitoring period. During the first quarter 2016, no cannery waste was <br />accepted <br />3.1.7 Domestic Well Monitoring <br />Two domestic wells (7898-A and 8106-A) were sampled on February 10, 2016. Table 3-5 <br />summarizes the current analytical results for the domestic well samples collected. PCE <br />was measured above the PQL in both domestic well samples, and cis-1,2- <br />dichloroethene, DCDFIVI, TCE were also measured above their PQLs in the sample <br />collected from well 8106-A. In addition, a trace concentration of 1,1-dichloroethane <br />was measured in well 8106-A, and DCDFM and TCE were measured at trace <br />concentrations in well 7898-A. <br />3.1.8 Vadose Zone Monitoring <br />The current vadose-zone monitoring network at the Austin Unit consists of seven <br />lysimeters. The lysimeter locations are shown on Figure 3-1. As shown on Table 2-6, <br />with the exception of FU -04W and FU -04E all of the lysimeters were reported dry, and <br />there was insufficient soil -pore liquid (<_ 5 mL) from FU -04W or FU -04E for analysis. <br />3.1.9 Leachate/Surface Impoundment Monitoring <br />Leachate sumps and surface impoundments are inspected weekly by Forward Landfill <br />personnel. If leachate is detected in a sump, it is pumped into the surface <br />impoundment WMU F (West) for evaporation. During the first quarter 2016, leachate <br />was observed at holding areas WMU FU -03, WMU FU -04, WMU FU -05, WMU FU -06, <br />WMU FU -13, and WMU FU -14 and a total of 197,800 gallons of leachate was removed <br />from the lined areas at an average rate of 2,174 gallons per day. For surface <br />impoundment WMU-F (West) freeboard ranged from approximately 6.58 to 10.00 feet <br />during the first quarter 2016 monitoring period.
