As proposed in the Revised EFS recently prepared for the existing Austin Road <br />Landfill by HA/AEE (2001), treated water would no longer be discharged to the <br />North Branch but, would instead, be reintroduced to the aquifer in the vicinity of <br />monitoring well MW -11. In combination with plans for an enhanced landfill gas <br />collection system, reintroduction of treated water to the aquifer is expected to <br />reduce existing VOC impacts below Maximum Contaminant Levels (MCLs) <br />(drinking water standards) within five years and below the Water Standard (one <br />part per billion) within nine years. <br />2.3 SURFACE WATER <br />2.3.1 SURFACE WATER PROTECTION <br />The only surface water bodies adjacent to the site are the North Branch and <br />South Branch of the South Fork of Little Johns Creek which are tributary to the <br />San Joaquin River. The North Branch has been realigned to flow to the north <br />and west of the Forward Landfill, and the South Branch flows along the <br />southern border. <br />0 2.3.2 SURFACE WATER MONITORING <br />C <br />Surface water monitoring is completed quarterly in accordance with the site's <br />WDR's. Monitoring is performed for the North Branch and South Branch of <br />Little Johns Creek (see Figure 4). Table 3 lists the surface water monitoring <br />stations at the site together with their current and expected future use. <br />The majority of the existing WMUs at the Forward Landfill contain blanket <br />leachate collection and removal system (LCRS) systems. There is no LCRS <br />on the base of the northerly unlined portion of the former Austin Road Landfill. <br />The Stage IA closure area will not include any of the lined areas that have <br />LCRS systems (i.e., WMU FU -03, FU -04, and FU -05). <br />Forward Landfill PFCPCMP 2-3 <br />Z:\PROJECTS\Allied Waste\Forward\Reference Files Prior JTDWune 05 Stage IA Partial FCPCMP\FL-sec2.doc: 6/16/2008 <br />
