FORWARD LANDFILL 9999 S.Austin Road <br /> Manteca,CA 95336 <br /> (209)982-4298,Fax(209)982-1009 <br /> April 28, 2014 <br /> J N: 2014-0012 <br /> Mr. Ross Atkinson RECEIVED <br /> Central Valley Regional Water Quality Control Board <br /> 11020 Sun Center Drive, Suite 200 APR, 3 0 2014 <br /> Rancho Cordova, CA 95670-6114 EWRONMENTAL HEALTH <br /> SUBJECT: FIRST QUARTER 2014 PERMIT/S <br /> ERVICES <br /> WATER QUALITY MONITORING REPORT <br /> FORWARD LANDFILL <br /> SAN JOAQUIN COUNTY,CALIFORNIA <br /> Forward Incorporated (Forward) is pleased to submit the subject water quality monitoring <br /> report for the Forward Landfill in compliance with reporting requirements of the Regional <br /> Water Quality Control Board - Central Valley Region (RWQCB) Waste Discharge Requirements <br /> (WDRs) Order Number 115-2014-0006. This report presents quarterly sampling results for the <br /> reporting period dating from January 1 to March 31, 2014 (first quarter 2014). <br /> According to the Forward Landfill Operations Manager, standard observations have been <br /> conducted weekly during the reporting quarter. The Forward Landfill Operations Manager also <br /> reported that no surface water was discharged from the facility during the reporting period. <br /> During the first quarter 2014 monitoring period, no notices of violation were issued by the San <br /> Joaquin County Environmental Health Department or RWQCB. <br /> For the Forward Unit, environmental monitoring for the first quarter 2014 yielded results <br /> similar to previous quarters. During the first quarter 2014 monitoring period, one volatile <br /> organic compound (VOC) (diisopropyl ether) was measured at a quantifiable concentration at <br /> well MW-2A. For the inorganic monitoring parameters, the concentration limit (CL) for nitrate <br /> as nitrogen was exceeded at well MW-14 and the CL for sulfate was exceeded at background <br /> well MW-24; however, neither of these wells exhibited a statistically significant increasing <br /> temporal trend. The organic and inorganic CL exceedances for compliance wells MW-2A and <br /> MW-14 are believed to be related to the groundwater gradient reversal in the northeast corner <br /> of the landfill beginning in 2011 and not the result of a release from the landfill, while the CL <br /> exceedance for well MW-24 is attributed to background conditions. Lysimeters and surface <br /> water sampling locations were dry during the first quarter 2014 monitoring period. <br /> Groundwater quality conditions beneath the Austin Unit during the first quarter 2014 <br /> monitoring period were generally similar to historical results. During the current monitoring <br /> period, no VOCs were identified at Detection Monitoring Program (DMP) wells. For the routine <br /> inorganic monitoring parameters, the CL for calcium was exceeded in DMP well AMW-7. <br /> However, a statistically significant increasing temporal trend was not calculated for calcium <br />
