GeoLogic Associates <br /> Geologists, Hydrogeologists and Engineers <br /> July 27,2007 <br /> JN: 2007-0043 <br /> Mr. Ross Atkinson <br /> Central Valley Regional Water Quality Control Board <br /> 11020 Sun Center Drive, Suite 200 <br /> Rancho Cordova, CA 95670-6114 <br /> SECOND QUARTER 2007 <br /> WATER QUALITY MONITORING REPORT <br /> FORWARD LANDFILL <br /> SAN JOAQUIN COUNTY,CALIFORNIA <br /> On behalf of Forward Incorporated(Forward), GeoLogic Associates (GLA)is pleased to submit <br /> the subject water quality monitoring report for the Forward Landfill in compliance with reporting <br /> requirements of the Regional Water Quality Control Board- Central Valley Region(RWQCB) <br /> Waste Discharge Requirements (WDRs)Order Number R5-2003-0049,which combined <br /> operations at the former Austin Road and Forward Landfills under a single permit. The <br /> combined landfills will be referred to as the Forward Landfill hereafter. The Forward Landfill is <br /> regulated by two monitoring programs including the RWQCB WDR Order No. R5-2003-0049; <br /> and the Department of Toxic Substances Control (DISC)Post Closure Permit No. CAD <br /> 990794133. A separate annual report is submitted to the DTSC in March each year addressing <br /> the Post Closure Permit Requirements and focuses on Waste Management Unit(WMU)A. <br /> However, all analytical data are provided in each report and the requirements of each program <br /> are being satisfied. This report presents quarterly sampling results for the reporting period dating <br /> from April 1 to June 30, 2007 (second quarter 2007). <br /> For the Forward Unit,environmental monitoring for the second quarter 2007 yielded results <br /> similar to previous quarters. One new historical intrawell maximum value was measured for <br /> bicarbonate in sample collected from groundwater monitoring well MW-IA during the second <br /> quarter 2007 monitoring period. Excluding suspected laboratory contaminants, estimated trace- <br /> level VOCs were measured in wells MW-10 and MW-14A; and one VOC was measured above <br /> the PQL in well MW-10. CLs were exceeded for one or more monitoring parameters in samples <br /> from 12 wells. In accordance with the RPCMP, eight wells with exceedances of CLs that are <br /> potential impact constituents will be resampled in August 2007 (during the third quarter 2007 <br /> sampling event), and a second independent sample will be collected in September 2007. The <br /> results of the two retests will be submitted to DTSC and RWQCB under separate cover. <br /> Historically, similar exceedances of CLs have been measured and verified in samples collected <br /> from DMP monitoring wells at the Forward Unit, followed by no release demonstrations (NRD), <br /> which have concluded that the CL exceedances are likely the result of naturally occurring <br /> conditions and therefore not indicative of a release from the Forward Landfill. <br /> 16885 W.
