The combined landfills are referred to as the Forward Landfill hereafter. The Forward Landfill is regulated by two monitoring programs including the RWQCB WDR Order No. R5-2003-0049; and the Department of Toxic Substances Control (DTSC) Post Closure Permit No. CAD 990794133. A separate annual report is submitted to the DTSC in March each year addressing the Post Closure Permit Requirements and focuses on Waste Management Unit(WMU) A. However, all analytical data are provided in each report and the requirements of each program are being satisfied. This report presents quarterly sampling results for the reporting period dating from April 1 to June 30, 2012 (second quarter 2012). During the second quarter 2012 monitoring period, a notice of violation(NOV) was issued by the San Joaquin County Environmental Health Department for construction of a perimeter road within the buffer area. Forward corrected the problem and no other NOVs were issued for the monitoring period. For the Forward Unit, environmental monitoring for the second quarter 2012 yielded results similar to previous quarters. Diisopropyl ether(RIPE) was measured above its practical quantitation limit(PQL) in the samples collected from wells MW-2A and MW-16. In addition, two volatile organic compounds (VOCs) were measured at estimated trace concentrations in the sample collected from well MW-14. Concentration limits (CLs) were exceeded for constituent concentrations in wells MW-2A, MW-13, MW-14, MW-15, and MW-16. Excluding non-impact constituents and low-level VOCs, confirmation sampling for chloride in well MW-13 and barium in well MW-14 will be performed in August 2012 during the third quarter 2012 monitoring event, and in September 2012. The results of the confirmation sampling will be provided under separate cover.
