chain-of-custody form and assigning a unique laboratory number to each <br /> sample. <br /> SaMplp Preservation and Shim{Z ent <br /> Sample containers will vary with each type of analytical parameter to <br /> be tested. Selected container types and materials will be nonreactive <br /> with the sample and the particular analytical parameter to be tested. <br /> As noted, sample containers will be properly cleaned and sterilized <br /> according to the EPA protocol for the specific analyses to be per- <br /> formed. All samples will be shipped on ice to EMCON's state-certified <br /> laboratory. Chain-of-custody documentation will accompany all sample <br /> containers. <br /> ANALYTICAL PROCEDURES <br /> The soil and ground-water samples will be analyzed in accordance with <br /> accepted quantitative analytical procedures. The following four <br /> publications are considered the primary references for soil and <br /> ground-water sample analyses, and the contracts with outside laborato- <br /> ries will stipulate that these methods be used: <br /> • Standard Methods for the Examination of Water and Waste- <br /> water, (American Public Health Association et al . , 16th <br /> edition, 1985) <br /> Metbads for Chemical Analysis of Water and Wastes (EPA- <br /> 600/4-79/020, revised March 1983) <br /> • Methods for Organic Chemical Analysis of Municipal and <br /> Industrial Wast we ater (EPA-600/4-82/057, July 1982) <br /> • Ipc__t Met ds for ]U ing Solid Waste: Physical/Chemi- <br /> sal Methods (EPA SW-846, 3rd edition, November 1986) <br /> The laboratory selected to perform the analytical work will be certi- <br /> fied by the California Department of Health Services as qualified to <br /> perform the selected analyses. Laboratories will be reviewed .by EMCON <br /> to verify that an adequate quality control program is followed. <br /> PJ9 9390313.00D <br />
