The enclosed,Monitoring Report Compliance Checklist summarizes our <br /> comments on the report. <br /> The source of low levels of volatile organic constituents (VOCs) in groundwater is likely from <br /> de-gassing of the old Forward Landfill units. Forward continues to control and remove landfill <br /> gas as a corrective action for VOC releases to groundwater. <br /> The groundwater remediation of the VOC contaminant plume associated with the old Austin <br /> Road Unit is ongoing. Recently, staff has been notified that PCE was detected in several <br /> water wells at the Northern California Youth Center (NCYC). The unlined Austin Road unit is a <br /> known source of chlorinated solvent groundwater pollution and is a likely source of the PCE. <br /> On 1 November 2006, staff requested a plan to investigate whether the Austin Road unit is the <br /> source of PCE in the NCYC wells. If the Austin Road Landfill proves to be the source of the <br /> VOCs, corrective actions will be required to remediate the groundwater pollution at the NCYC <br /> site. <br /> if you have any questions please call me at (916) 464-4614. <br /> Ross D.
