APPENDIX A <br /> SAMPLING AND ANALYSIS PROCEDURES <br /> INTRODUCTION <br /> The sampling and analyses procedures for the monitoring program at the San Joaquin County <br /> sanitary landfills are contained in this appendix. The procedures will provide for consistent and <br /> reproducible sampling methods; proper application of analytical methods; and accurate and precise <br /> analytical results; and finally, guidelines so that the overall objectives of the monitoring program <br /> are achieved. <br /> The following documents have been used as guidelines for the development of these procedures: <br /> ® Procedures Manual for Groundwater Monitoring at Solid Waste Disposal Facilities, U.S. <br /> Environmental Protection Agency(USEPA)-530/SW-611,August 1977 <br /> • RCRA Groundwater Monitoring Technical Enforcement Guidance Document, OSWER <br /> 9950.1, September 1986 <br /> • Test Methods for Evaluating Solid Waste: Physical/Chemical Methods,USEPA SW-846, <br /> 3rd edition,November 1986 <br /> • Methods for Organic Chemical Analysis of Municipal and Industrial Wastewater, <br /> USEPA-600/4-82-057,July 1982 <br /> • Methods for Chemical Analysis of Water and Wastes, USEPA-600/4-79-020, revised <br /> March 1983 <br /> GROUNDWATER ELEVATION SURVEY <br /> Before the sampling event is begun, monitoring wells at the site will be measured for static water <br /> levels during a single water level survey. Water levels will be converted to elevations in mean sea <br /> level and displayed on a groundwater contour map. All (or selected) monitoring wells will be <br /> sampled for chemical constituents after the water level survey is completed. <br /> SAC\S:\WES\S&APR0C.D0C-95\w:1 1 <br />
