FORWARD LANDFILL 9999 S. Austin Road <br /> Manteca, CA 95336 <br /> (209)982-4298, Fax (209)982-1009 <br /> April 29,2009 <br /> JN: 2008-0010 <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 /> FIRST QUARTER 2009 <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 <br /> submit the subject water quality monitoring report for the Forward Landfill in compliance <br /> with reporting requirements of the Regional Water Quality Control Board- Central <br /> Valley Region(RWQCB)Waste Discharge Requirements(WDRs)Order Number R5- <br /> 2003-0049,which combined operations at the former Austin Road and Forward Landfills <br /> under a single permit. The combined landfills will be referred to as the Forward Landfill <br /> hereafter. The Forward Landfill is regulated by two monitoring programs including the <br /> RWQCB WDR Order No. R5-2003-0049;and the Department of Toxic Substances <br /> Control(DISC)Post Closure Permit No. CAD 990794133. A separate annual report is <br /> submitted to the DTSC in March each year addressing the Post Closure Permit <br /> Requirements and focuses on Waste Management Unit(WMU)A. However,all <br /> analytical data are provided in each report and the requirements of each program are <br /> being satisfied. This report presents quarterly sampling results for the reporting period <br /> dating from January 1 to March 31,2009(first quarter 2009). <br /> For the Forward Unit, environmental monitoring for the first quarter 2009 yielded results <br /> similar to previous quarters. During the monitoring period,four new historical intrawell <br /> maximum values were measured in samples collected from groundwater monitoring <br /> wells,however,three of the intrawell maximum values are for chloromethane,a <br /> suspected field/laboratory contaminant. Seven estimated trace-level volatile organic <br /> compounds(VOCs)were measured in wells -10 and MW-14;while one VOC <br /> (tetrachloroethene)was measured above its practical quantitation limit(PQL)in well <br /> MW-14. In addition, the semi-volatile organic compound(bis(2-ethylhexyl)phthalate) (a <br /> suspected laboratory contaminant)was measured at a trace concentration in well MW-24. <br /> Concentration limits (CLs)were exceeded for one or more monitoring parameters in <br /> samples from 11 wells. Historically,similar exceedances of inorganic CLs have been <br /> measured and verified in samples collected from detection monitoring program(DMP) <br /> monitoring wells at the Forward Unit,followed by no release demonstrations,which have <br /> concluded that the inorganic CL exceedances are likely the result of naturally occurring <br /> conditions and therefore not indicative of a release from the Forward Landfill.
