APPENDIX A <br /> SAMPLING AND ANALYSIS PROCEDURES <br /> The sampling procedures for water quality monitoring programs are contained in this appendix. <br /> The procedures provided for consistent and reproducible sampling methods, proper application of <br /> analytical methods, and accurate and precise analytical results. Finally, these procedures provided <br /> guidelines so that the overall objectives of the monitoring program were achieved. <br /> The following documents have been used as guidelines for developing these procedures: <br /> • Procedures Manual for Groundwater Monitoring at Solid Waste Disposal Facilities, <br /> Environmental Protection Agency (EPA)-530/SW-611, August 1977 <br /> • Resource Conservation and Recovery Act (RCRA) Groundwater Monitoring Technical <br /> Enforcement Guidance Document, Office of Solid Waste and Emergency Response <br /> (OSWER) 9950.1, September 1986 <br /> %`'e • Test Methods for Evaluating Solid Waste: Physical/Chemical Methods, EPA SW-846, <br /> 3rd edition, November 1986 <br /> • Methods for Organic Chemical Analysis of Municipal and Industrial Waste Water, <br /> EPA-600/4-82-057,July 1982 <br /> • Methods for Organic Chemical Analysis of Water and Wastes, EPA-600/4-79-020, <br /> revised March 1983 <br /> • Leaking Underground Fuel Tank (LUFT) Field Manual, California State Water <br /> Resources Control Board,revised October 1989 <br /> Sample Collection <br /> Sample collection procedures include equipment cleaning, water level and total well depth <br /> measurements, and well purging and sampling. <br /> Equipment Cleaning <br /> Before the sampling event was started, equipment that was used to sample groundwater was <br /> disassembled and cleaned with detergent water and then rinsed with deionized water. During field <br /> sampling, equipment surfaces that were placed in the well or came into contact with groundwater <br /> SA"-.\PJ0\0805\08051140.8BS-96`cjb:2 A-I Rev.0,923/97 <br />
