FORWARD LANDFILL 9999 S. Austin Road Manteca,CA 95336 (209)982-4298,Fax(209)982-1009 January 29, 2014 JN: 20t3-0021 Mr. Ross Atkinson Central Valley Regional Water Quality Control Board 11020 Sun Center Drive, Suite 200 Rancho Cordova, CA 95670-6114 SUBJECT: FOURTH QUARTER 2013 & ANNUAL WATER QUALITY MONITORING REPORT FORWARD LANDFILL SAN JOAQUIN COUNTY, CALIFORNIA Forward Incorporated(Forward) is pleased to submit the subject water quality monitoring report for the Forward Landfill in compliance with reporting requirements of the Regional Water Quality Control Board - Central Valley Region(RWQCB) Waste Discharge Requirements (WDRs) Order Number R5-2003-0049, which combined operations at the former Austin Road and Forward Landfills Linder a single permit. 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 (DISC) Post Closure Permit No. CAD 990794133. This report presents the fourth quarter 2013 sampling results and also provides an annual summary of the results from the 2013 monitoring year. During the fourth quarter 2013 monitoring period,no notices of violation (NOV) was issued by the San Joaquin County Environmental Health Department. For the Forward Unit, no significant changes in the water quality analytical results were noted. During the fourth quarter 2013 monitoring period, only one volatile organic compound (VOC) (dichlorodifluoromethane) was measured at a trace concentration in the sample collected froin well MW-10. For the inorganic monitoring parameters, Concentration Limits (CLS) were exceeded for constituent concentrations in wells MW-2A, MW-13, ?V[W-14, MW-15 and background well NIW-23R. Statistically significant increasing temporal trends were identified for chloride concentrations in well MW-2A, nitrate-N concentrations in well MW-14, and sulfate concentrations in well MW-15. However, review of groundwater flow directions suggests that the increasing trends for inorganic constituents may be related to changing conditions in background associated with agricultural activities. Surface water sampling locations for the Forward and Austin Units were dry during the fourth quarter 2013 monitoring period. The annual leachate monitoring results for the Forward Unit are generally similar to historical results. Two VOCs, 14 metals constituents, and numerous inorganic constituents were detected in the annual sample. No semi-VOCs (SVOCs), herbicides or pesticides were detected, and no new Constituents of Concern (COCs) were detected.
