Water Quality Monitoring Report Forward Landfill monitoring period. Appendix A presents copies of the leachate observation logs, freeboard observation logs, and surface impoundment monitoring log. Leachate samples are analyzed in the field for pH, specific conductance, temperature, and turbidity on a quarterly basis. In addition to the quarterly monitoring, leachate was sampled for the annual list of list of parameters listed in Table 2-1. Results of quarterly field monitoring measurements for the first quarter 2015 and annual analytical results are presented in Table 2-6. 2.1.7 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 from the Forward Unit to surface water during the reporting period. Surface water monitoring stations FSW-1 (downstream) and FSW-2 (upstream) were sampled on February 25, 2015 for the first quarter 2015 monitoring period. Table 2-7 summarizes the current analytical results of surface water samples collected at the Forward Unit. As shown on Table 2-7, no VOCs were detected in either sample, and no CLs were exceeded for FSW-1. 2.2 Summary Groundwater quality conditions beneath the Forward Unit during the first quarter 2015 monitoring period are generally similar to those observed in previous monitoring periods. A non-statistical indication of release was identified at well MW-13 as a result of one VOC measured at a quantifiable concentration, and at well MW-14 as a result of three VOCs measured at estimated-trace concentrations. No other VOCs were detected in groundwater samples during the first quarter 2015 monitoring period. For the inorganic monitoring parameters, one or more CLs were exceeded at wells MW-2A and MW-18. Verification sampling for the organic and inorganic CL exceedances is scheduled for April 2015. Surface water samples collected from the upstream and downstream surface water monitoring stations during the first quarter 2015 monitoring period are generally consistent with each other; no VOCs were detected and no CLs were exceeded. For vadose zone monitoring up to eight VOCs were detected in soil- pore liquid samples and approximately 2350 gallons of liquid was pumped from pan lysimeter WMU-D01N.
