Volatile organic compounds (VOC)were historically detected in groundwater well MW-2. CFC-12 and <br /> 1, 2-Dichloropropane are no longer detected in MW-2 (since 2007). Tetrachloroethene (PCE) and Toluene <br /> are currently at trace concentrations. <br /> ' The statistical software indicates an increasing trend for several inorganic constituents at MW-2; however, the <br /> historical data shows a fluctuation of these parameters at MW-2 and current concentrations are within the <br /> historical range. The groundwater at all monitoring wells meets drinking water standards. <br /> ' Data from groundwater wells MW-5 and MW-6; which are up-gradient of the landfill and MW-4, indicate that <br /> the residential wastewater treatment ponds north of the site have an impact on the groundwater; however, <br /> ' these effects dissipate as the groundwater flows into the landfill at well MW-4. <br /> I certify under penalty of perjury that I am familiar with the information submitted in this report, and to the best <br /> of my knowledge the report is true, accurate, and complete. <br /> ' If you have any questions, please contact me at(209) 953-7316. <br /> ' Sincerely, <br /> TAJ M.
