Water Quality Monitoring Report Forward Landfill leachate observation logs, freeboard observation logs, and surface impoundment monitoring log. Leachate samples were collected on a quarterly basis and analyzed in the field for pH, specific conductance, temperature, and turbidity. The results of quarterly field monitoring measurements for the first quarter 2016 are presented in Table 3-7. 3.1.10 Surface Water Monitoring Site run-on and run-off control facilities are designed to effectively channel surface water to site stormwater/sedimentation ponds. According to the Operations Manager, there were no discharges to surface water during the reporting period. Surface water monitoring stations ASW -1 (upstream) and ASW -2 (downstream) were sampled on February 9, 2016 for the first quarter 2016 monitoring period. Table 3-8 summarizes the current analytical results of surface water samples collected at the Austin Unit. As shown on Table 3-8, the results are similar and no VOCs were detected in either sample. Furthermore, no CLs were exceeded for downstream point ASW -2. 3.1.11 Corrective Action Monitoring The Groundwater Treatment Facility (GTF) at the Austin Unit has been operational since 1994 to mitigate impacts from landfill releases. Impacted groundwater is extracted from four wells (EW -1, EW -2, EW -3R, and EW -4) that pump groundwater through an air stripper treatment system to remove VOCs. Treated groundwater is discharged to an infiltration pond (constructed in 2003) north of the Austin Road Unit of the Forward Landfill. During the monitoring period, the GTF treated 22.5 million gallons of groundwater and removed approximately 1.58 pounds of VOCs. Details regarding corrective action remediation system operations and performance evaluation for the first quarter 2016 are presented in Appendix C. 3.2 Summary Groundwater quality conditions beneath the Austin Unit during the first quarter 2016 monitoring period were generally similar to historical results. With the exception of well AMW-6, only one CL was exceeded for DMP wells during the current monitoring period. Verification sampling for the CL exceedance at well AMW-5R is scheduled for April 2016. Although, several CLs were exceeded and several VOCs were detected in well AMW-6, and it is recognized that well AMW-6 should have been identified a CAP well in the M&RP. For the CAP/evaluation wells, 17 of 28 wells reported one or more VOCs exceeding a PQL, with CAP well AMW-1 having the greatest number of VOCs (14), including seven measured above a PQL. Surface water samples collected from the upstream and downstream surface water monitoring stations during the first quarter 2016 monitoring period are generally consistent with each other and no VOCs were detected. All of the lysimeters were reported dry or there was an insufficient volume of M:\ 2016.0007\FA 1Q16.docx 13
