Surface water samples are analyzed for the following field and monitoring parameters <br /> semiannually: <br /> • Temperature • Chloride <br /> • Electrical Conductivity • Sulfate <br /> • pH • Nitrate-Nitrogen <br /> • Turbidity • Calcium <br /> • Total Dissolved Solids • Magnesium <br /> • Carbonate Alkalinity • Sodium <br /> • Bicarbonate Alkalinity • Potassium <br /> • VOCs <br /> Surface water samples are also analyzed for the following COCl every 5 years: <br /> • Total Organic Carbon <br /> • Inorganics (dissolved) <br /> • VOCs (extended list) <br /> • Semi-Volatile Organic Compounds <br /> • Chlorophenoxy Herbicides <br /> • Organophosphorous Compounds <br /> Surface water samples were last analyzed for COCs during the fourth quarter 2004 monitoring <br /> event. The next monitoring event for surface water COCs will occur during the first quarter of <br /> 2010. <br /> Leachate <br /> Leachate samples are collected monthly from the sump under module 1. Field parameters <br /> measured monthly include: <br /> • Total flow • Flow rate <br /> • pH • Electrical Conductivity <br /> Leachate samples are analyzed annually for the following parameters as specified in the WDRs: <br /> • Chloride • Nitrate-Nitrogen <br /> • Total Dissolved Solids (TDS) • Sulfate <br /> • Calcium • Potassium <br /> • Magnesium • Sodium <br /> • Carbonate Alkalinity • Bicarbonate Alkalinity <br /> • VOCs <br /> Foothill Sanitary Landfill 5 Department of Public Works/Solid Waste <br /> 2°d Semester Groundwater Monitoring County of San Joaquin-January 31,2007 <br />
