Box 1810 <br /> Stockton, CA 95201 <br /> REVIEW OF FIRST QUARTER 2007 GROUNDWATER AND SURFACE WATER <br /> MONITORING REPORT FOR THE HARNEY LANE SANITARY LANDFILL <br /> The Regional Water Quality Control Board (Regional Water Board) staff has reviewed the First <br /> Quarter 2008 Groundwater and Surface Water Monitoring Report for the Harney Lane <br /> Sanitary Landfill. The Report was prepared in accordance with Waste Discharge Requirement <br /> Order No. 96-139. Analytical results for the 1st Quarter indicate that volatile organic <br /> compounds (VOCs) continue to be detected in groundwater wells MW-1 and MW-2. The <br /> Discharger has proposed to install additional gas extraction wells thus increasing corrective <br /> action in the vicinity of well MW-2. Please submit a schedule of the proposed extraction well <br /> installation by 6 June 2008. <br /> Please review the attached Monitoring and Reporting Checklist. If you have any questions <br /> please call me at 916-464-4737. <br /> Todd A.
