2.2 GROUNDWATER <br /> 2.2.1 GROUNDWATER MONITORING WELLS <br /> The groundwater monitoring network at the Forward Landfill has been <br /> designed to provide early detection of a release from wastes to groundwater. <br /> The monitoring systems installed were designed and certified by a registered <br /> (geologist or civil) engineer. The boring logs were prepared under the direction <br /> of a registered (geologist or civil) engineer and have been submitted to the <br /> RWQCB. <br /> As shown on Table 1 and depicted on Figure 4, the monitoring well network <br /> includes 40 wells; 12 for post-closure monitoring of WMU-A, 27 additional wells <br /> for the Detection Monitoring Program (DMP); and 11 wells to monitor the <br /> effectiveness of the Corrective Action Program (CAP) north of the existing <br /> Austin Road parcel. <br /> Of the 40 wells, 5 wells have not yet been constructed, but are proposed to <br /> meet DMP and CAP monitoring requirements. The locations of the proposed <br /> CAP wells were selected based on comments presented by the RWQCB in <br /> their letter to Forward Landfill Inc., dated June 22, 2001. As requested by the <br /> RWQCB, the new CAP wells will be constructed to monitor both shallow and <br /> deep groundwater zones. The locations for the proposed DMP wells were <br /> selected to provide additional spatial coverage for the new landfill expansion. <br /> The design for all new monitoring wells will be detailed in a work plan that will <br /> be prepared under the supervision of a certified (geologist or civil) engineer. <br /> Similarly, all well construction work will be performed under the direction of a <br /> certified (geologist or civil) engineer. Table 1 lists the monitoring parameters <br /> 2.2.2 GROUNDWATER CONTROL <br /> Two groundwater extraction wells (EW-1 and EW-2) with a combined design <br /> capacity of 305 gallons per minute (gpm) were installed to extract impacted <br /> groundwater at the existing Austin Road Landfill (see Figure 4). VOCs are <br /> stripped from the extracted water at the facility's groundwater treatment plant, <br /> and the treated water is currently discharged to the North Branch. The <br /> groundwater treatment system and discharge are regulated under the Waste <br /> Discharge Requirements (WDR) Order No. R5-2003-0049. <br /> Forward Landfill PFCPCMP 2-2 <br /> Z:\PROJECTS\Allied Waste\Forward\Reference Files Prior JTD\June 05 Stage IA Partial FCPCMP\FL-sec2.doc:6/16/2008 <br />
