ATTACHMENT A <br /> SAMPLING AND ANALYSIS PROCEDURES <br /> The sampling procedures for water quality monitoring programs are contained in this attachment <br /> The procedures provided for consistent and reproducible sampling methods, proper application of <br /> analytical methods, accurate and precise analytical results, and 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 far Groundwater Monitoring at Solid Waste Disposal Facilities, <br /> Environmental Protection Agency(EPA)-530/SW-61 1, August 1977 <br /> • Resource Con,�ervrrtaon and Recovery Act (RCRA) GiWitulwute► Monttorrn� Technical <br /> Enforcement Guidance Document, Office of Solid Waste and Emergency Response <br /> (OS WER) 9950 1, September 1956 <br /> • Test Methods for Evaluating Salad Waste PhysicallChemical Methods, EPA SW-846, 3rd <br /> edition, November 1986 <br /> o Methods for Organic Chemical Analysis of Municipal and Indust►aal Wastewater, <br /> EPA-60014-82-057, July 1982 <br /> • Methods for Chemical Analysis of Water and Wastes, EPA-60014-79-020, revised March <br /> 1983 <br /> • Leaking Underground Fuel Tank (LUFT) Field Manual, California State Water Resources <br /> 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 deiontzed water During <br /> field sampling, Equipment surfaces that were placed in the well or came into contact with <br /> groundwater during field sampling, were steam cleaned with detonized water before the next well <br /> was purged or sampled <br />
