MW-7 (Up-gradient): <br /> ® All constituents were within the tolerance limits in 2012, except for EC which exceeded <br /> tolerance limits in the 3rd Quarter 2012. <br /> No VOCs were reported in well MW-7 this year. <br /> MW-8: <br /> All general water quality constituents were within the tolerance limits in 2012. The trend <br /> analysis indicates decreasing trends in Chloride,Nitrate as Nitrogen, and Sulfate. <br /> Seven VOCs were reported in well MW-8 this year. The VOCs detected in this well are <br /> generally among the same VOCs found in MW-5, but at equal or lower concentration. The area <br /> around MW-5 is believed to be the source of VOCs at MW-8. <br /> Trend analysis of VOC concentrations indicates increasing trends for four VOCs, decreasing <br /> trends for one VOC and no trends for four VOCs. <br /> MW-9A(Newly-installed): <br /> MW-9A has been monitored for three quarters. Concentrations of all parameters were within <br /> established concentration limits where the limits could be determined in 2012. <br /> Two VOCs were reported in wellMW-9A this year. The VOCs detected in this well are among <br /> the VOCs found in MW-5 and MW-8, at lower concentrations. It is our opinion that MW-5 is <br /> closer to the source of the VOCs and thus has more VOCs. <br /> Data is not sufficient to establish a trend in this well. <br /> MW-l0A(Newly-installed, Impacted): <br /> MW-l0A has been monitored for three quarters. Concentrations of all parameters were within <br /> established concentration limits where the limits could be determined in 2012. <br /> Three VOCs were reported in well MW-l0A this year. The VOCs detected in this well are <br /> among the VOCs found in MW-5 and MW-8, at lower concentrations. It is our opinion that <br /> MW-5 is closer to the source of the VOCs and thus has more VOCs. <br /> Data is not sufficient to establish a trend in this well. <br /> MW-11A (Newly-installed, Impacted): <br /> MW-1 IA has been monitored for three quarters. Concentrations of all parameters were within <br /> established concentration limits where the limits could be determined in 2012. <br /> • <br /> Corral Hollow Sanitary Landfill 18 Department of Public Works/Solid Waste <br /> 4th Quarter and Annual 2012 Groundwater Monitoring County of San Joaquin—January 15,2013 <br />
