0 2.2 Summary • Water Quality Monitoring Report Forward Landfill Groundwater quality conditions beneath the Forward Unit during the fourth quarter 2014 monitoring period are generally similar to those observed in previous monitoring periods. A non -statistical indication of release was identified at well MW -2A as a result of one VOC (DIPE) measured at a quantifiable concentration. No other VOCs were measured above a quantifiable concentration in groundwater samples collected during the fourth quarter 2014 monitoring period. For the inorganic monitoring parameters, no CLs were exceeded during the monitoring period. Surface water samples collected from the upstream and downstream surface water monitoring stations during the fourth quarter 2014 monitoring period are generally consistent with each other; no VOCs were detected and no CLs were exceeded. Of the vadose zone monitoring points, two VOCs were detected in soil -pore liquid samples and approximately 200 gallons of liquid was pumped from pan lysimeter WMU-D01N. 3.0 AUSTIN UNIT 3.1 Water Quality Monitoring 3.1.1 Sampling and Laboratory Analyses Del -Tech performed routine monitoring of DMP, CAP, EMP wells at the Austin Unit during the fourth quarter 2014 monitoring period. Depth -to -water measurements were recorded in the groundwater monitoring wells on November 14, 2014. Groundwater and leachate sampling was performed between November 14 and 19, 2014, and surface water samples were collected on December 17, 2014. Samples were collected from each sample point with sufficient liquid and submitted to BC for analysis of the routine monitoring parameters stipulated in RWQCB Order No. 135- 2014-0006. Table 2-1 presents the monitoring schedule and summarizes the analytical methods utilized during the current monitoring period. Wells AMW-1, AMW-7, AMW- 10, and AMW-13 were also sampled for total arsenic, nitrogen, iron, and manganese for the CWLAM program. Water quality samples were also analyzed in the field for ORP, turbidity, temperature, specific conductance, and pH and recorded on well data sheets. The groundwater monitoring wells, surface water monitoring locations, and leachate were sampled in accordance with the sampling and analysis plan detailed in Appendix E. The well data sheets, raw laboratory data, certificates of analyses, and chain -of -custody records related to the sampling program are included in Appendix F. Field and laboratory analyses are summarized in Tables 3-1 through 3-8 and cumulative tabulated data for all monitoring points and constituents for groundwater, unsaturated zone, leachate, and surface water are presented in Appendix F.
