® As shown in the table above, significant increasing trends were calculated for three VOC constituents in CAP well AMW-1, while decreasing VOC trends were noted for several VOCs in CAP wells AMW-1, AMW-4, AMW-10, and AMW-19BR. The increasing trend exhibited for cis-1,2-DCE at well AMW-1, and generally decreasing(organic and inorganic) trends noted in all of the CAP wells, suggests that corrective action measures have been successful in reducing facility related groundwater impacts downgradient of the Austin Unit. Domestic Well Monitoring Two domestic wells (7898-A and 8106-A)were sampled on June 18, 2013. Table 3-3 summarizes the current analytical results for the domestic well samples collected. PCE was measured above the PQL in the samples from both domestic wells and DCDFM and TCE were measured above the PQL in the sample collected from well 8106-A. Estimated-trace concentrations of two VOCs were also measured in the samples collected from wells 7898-A and 8106-A. 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 quarter. Samples were collected ® from surface water monitoring stations ASW-1 (upstream) and ASW-2 (downstream) on June 18, 2013 for the second quarter 2013 monitoring period. Table 3-5 summarizes the current analytical results of surface water samples collected at the Austin Unit. As shown on Table 3-5, no VOCs were detected in either sample. Analytical results for the surface water samples are generally similar, suggesting that landfill operations are not impacting surface water quality. Leachate Monitoring According to the Operations Manager, no leachate was taken off site during the second quarter 2013. The leachate collection system,which collects leachate from the north face of the landfill, has been operational since November 1996. WQPS (concentration limits) are not required for leachate because it is collected and removed for disposal,rather than discharged. According to the Operations Manager, the LCRS operated effectively during the second quarter 2013. Leachate samples were collected on a monthly basis and analyzed in the field for pH, specific conductance, and temperature. The results of monthly field monitoring measurements are presented in Table 3-6. In addition, the semi-VOC (2-methylphenol) was detected for the first time during the annual leachate sampling event(fourth quarter 2012). Therefore, in accordance with Order No. 5-2003-0049, a confirmation (retest) sample was collected during the second quarter 2013 on June 18, 2013. As summarized in Table 3-6, 2-methylphenol was confirmed in the retest sample. C:U013-0021TA_2Q13.doe 11 Geo-Logic Associates
