APPENDIX A <br /> SAMPLING AND ANALYSIS PROCEDURES <br /> Introduction <br /> The sampling and analysis procedures for the monitoring programs at LF-1 and LF-2 are <br /> contained in this appendix. The procedures provide consistent and reproducible sampling <br /> methods; proper application of analytical methods; accurate and precise analytical results; <br /> and finally, these procedures provide guidelines so that the overall objectives of the <br /> monitoring program are achieved. <br /> The following documents have been used as guidelines for the development of these <br /> procedures: <br /> • Procedures Manual for Groundwater Monitoring at Solid Waste Disposal <br /> Facilities,Environmental Protection Agency(EPA)-530/SW-611,August 1977 <br /> • Resource Conservation and Recovery Act Groundwater Monitoring Technical <br /> Enforcement Guidance Document, Office of Solid Waste and Emergency <br /> Response 9950.1, September 1986 <br /> • Test Methods for Evaluating Solid Waste: Physical/Chemical Methods, EPA <br /> SW-846, 3rd edition,November 1986 <br /> • Methods for Organic Chemical Analysis of Municipal and Industrial Wastewater, <br /> EPA-600/4-82-057,July 1982 <br /> • Methods for Chemical Analysis of Water and Wastes, EPA-600/4-79-020, revised <br /> March 1983 <br /> Groundwater Elevation Survey <br /> Before the sampling event is begun, monitoring wells at the site are measured for static <br /> water levels during a single water level survey. Water levels are converted to elevations <br /> in mean sea level and displayed on a groundwater contour map. All (or selected) <br /> monitoring wells are sampled for chemical constituents after the water level survey is <br /> completed. <br /> Water levels are measured with an electric sounder. The electric sounder is a <br /> transistorized instrument that uses a reel-mounted, two-conductor, coaxial cable that <br /> Foothill WQPS Rev Ldoc <br /> A-I <br />
