MONITORING AND REPORTING PROGRAM -8- <br /> SOILS RECYCLING FACILITY <br /> WESTERN SOILS RECYCLING <br /> CALIFORNIA WASTE REMOVAL SYSTEMS <br /> SAN JOAQUIN COUNTY <br /> The Discharger shall determine at each sampling whether there is a statistically <br /> significant increase over water quality protection standards for each parameter <br /> and constituent analyzed. <br /> The ground water surface elevation (in feet and hundredths, M.S.L. ) in all wells <br /> shall be measured each time a well is sampled and used to determine the velocity <br /> and direction(s) of ground water flow. This information shall be displayed on a <br /> water table contour map and/or ground water flow net for the site. <br /> WATER QUALITY PROTECTION STANDARDS <br /> Quarterly samples shall be taken from "background" monitoring wells for one year <br /> and analyzed for: <br /> Report in <br /> Parameter/Constituent Units of <br /> Specific Conductance (field) ,umhos/cm <br /> pH (field) pH units <br /> Sulfate mg/l <br /> Chloride mg/1 <br /> Nitrate (as N) mg/1 <br /> Alkalinity mg/1 <br /> Carbonate mg/l <br /> Bicarbonate mg/l <br /> Dissolved Iron mg/l <br /> Manganese mg/l <br /> [Dissolved] or [Total] Organic Carbon mg/l <br /> Quarterly samples shall be taken from these wells for one year and analyzed for <br /> each of the parameters and constituents listed under "GROUND WATER MONITORING" <br /> above. Analyses shall account for measurement errors in sampling and analysis. <br /> Data from these analyses shall be reported to the Board by 1 March 1993 for use <br /> by the Board in determining water quality protection standards for ground water <br /> at the site. <br /> If subsequent sampling of "background" monitoring wells indicates signif ; .ant <br /> water quality changes due to either seasonal fluctuations or other reasons <br /> unrelated to waste management activities at the site, the Discharger may request <br /> modification of these water quality protection standards. <br /> Statistical Procedures for Determining Significant Increases <br /> The significance of increases in indicator parameters and waste constituents over <br /> water quality protection standards shall be established through the use of <br />
