The following table summarizes CL exceedances for VOCs during the 2013 monitoring year.

On behalf of Forward Inc.,GLA prepared a letter report dated February 14, 2001 (RWQCB Case No. 2209), to assess the source and potential impacts of low-level VOCs in groundwater adjacent to the Forward Landfill. The letter report concluded that the sporadic detection of low-level VOCs in groundwater(and lysimeter samples) at the Forward Unit are most likely due to landfill gas from unlined unit WMU-B. Forward has continued to minimize gas related impacts to groundwater by minimizing interim fill areas that promote ponding of water. Forward continues to install additional landfill gas ® extraction wells, as needed. Surface Water Site run-on and run-off control facilities are designed to effectively channel surface water to lined holding and evaporation ponds on site. According to the Operations Manager, no surface water was discharged from the facility during the 2013 monitoring year. Samples were collected during all monitoring periods except for the fourth quarter 2013 because the surface water stations were dry. Comparisons of the water quality data from upgradient(FSW-1) and downgradient(FSW-2) surface water stations during the 2013 monitoring year indicates similar concentrations, suggesting that landfill operations are not impacting surface water quality. Leachate Monitoring Leachate sumps are inspected for the presence of leachate and observations are recorded at least weekly by Forward Landfill personnel. If leachate is detected in a sump it is pumped into the surface impoundments (WMU-F North and WMU-F West)for evaporation. During the 2013 monitoring year, leachate was observed at all of the holding areas except WMU D-87 and WMU D-88 A/B. Freeboard at WMU-F North and WMU-F West ranged from approximately 1.83 to 8.50 feet during the 2013 monitoring year. ® C:U013-0021\FA_4Q13.dw 15 Geo-Logic Associates
