All wells in LF-1 will continue to be monitored and tuned to maximize LFG recovery operations without stressing methanogens or causing air infiltration. The tuning of the 13 extraction wells in LF-1 could continue into the spring of 2017 before optimum vacuum settings throughout the entire field are obtained. Wells GX-14, GX-15, GX-16, and GX-17 are healthy wells located in the new waste of lined landfill LF-2 and are not associated with the EFS for LF-1. Their monitoring results indicate they are good producers of methane and should continue to be monitored and tuned until the optimum vacuum setting is determined. .0 SUMMARY AND CONCLUSIONS The initial soil gas testing of the deepest probe from new tri-level SG-2A, SG-3A, SG-6A, and SG-11A indicated that VOCs were detected in all samples. As an immediate follow up action, SCS has been instructed to collect TO-15 samples from all levels of the new tri-level SG probes to assist the County in assessing the extent of the LFG migration. The data from a complete second round of testing of the tri-level SG probes will be reported in Second 2016 Semiannual Monitoring Report. The analytical results from existing single-level probes SG-1, SG-4, SG-5, SG-7, SG-8, SG-9, and SG-10 are consistent with previous test results, indicating VOCs were detected in all locations. All wells in LF-1 will continue to be monitored and tuned to maximize LFG recovery operations without stressing methanogens or causing air infiltration. The tuning of the 13 extraction wells in LF-1 could continue into the spring of 2017 before optimum vacuum settings throughout the entire field are obtained. Following the collection of a complete set of TO-15 analytical results for the new tri- level probes a Phase II investigation work plan and schedule will be developed. The Phase II work plan and schedule will be included in the Second 2016 Semiannual Monitoring Report. 7.0 LIMITATIONS The services described in this report were performed consistent with generally accepted professional consulting principles and practices.
