MONITORING AND REPORTING PROGRAM FOR -3- SAN JOAQUIN COUNTY AND THE CITY OF TRACY CORRAL HOLLOW SANITARY LANDFILL CLASS III LANDFILL SAN JOAQUIN COUNTY 1 Inductively Coupled Argon Plasma Atomic.__Emiss_ion Spectroscopy,_- (ICAP) may be used for analysis of these constituents only. 2 EPA Methods 601 and 602, or EPA Method 624 shall be used. All peaks shall be reported. - - M_ __.�,_._ The Discharger shall determine at each sampling whether there is a statistically significant increase over water quality protection standards for each parameter and constituent analyzed. The ground water surface elevation (in feet and hundredths, M.S.L.) in all wells shall be measured on a quarterly basis and used to.determine the velocity and direction(s) of ground water flow. This information shall be displayed on a water table contour map and/or ground water flow net for the site. WATER QUALITY PROTECTION STANDARDS Standards for Surface Waters _. Quarterly surface water samples shall be taken from Corral Hollow Creek upgradient of the site for one year and analyzed for each of the �t parameters and constituents listed under SURFACE WATER MONIjTORING above. Analyses shall account for measurement errors-in_sampiing and analysis. Data from these analyses shall be reported to the Board within thirteen months of the effective date of this Order for use by the Board in determining water quality protection standards 'for surface waters at the site. If subsequent upstream surface water sampling indicates signirkant water quality changes due to either seasonal fluctuations or other reasons unrelated to waste management _activities at the site, the Discharger may request modification of these water quality protection standards. Standards for Ground Water Quarterly samples shall be taken from all of the monitoring wells (MW -1 through MW -5) for one year and analyzed for each of the parameters and constituents listed under "GROUND WATER MONITORING" above. --Analyses shall account for measurement errors in sampling and analysis,_ Data from these analyses shall be reported to the Board within thirteen months of the effective date of this Order for use by the Board in determining water quality protection standards for ground water at the site.
