Specific <br /> decontamination procedures for all sampling equipment included washing in a TSP and tap <br /> water solution followed by two distilled water rinses. <br /> wq <br /> S { <br /> I C <br /> ,d= <br /> 4.0 ANALYTICAL CHEMISTRY PROCEDURES AND RESULTS <br /> i <br /> Fw This section discusses the analytical chemistry procedures and resulting data. <br /> d 1 4.1 ANALYTICAL CHEMISTRY PROCEDURES <br /> All groundwater samples were collected, transported,and analyzed in general accordance with <br /> U.S. Environmental Protection Agency (EPA)document SW-846, "Test Methods for Evaluating <br /> k y Solid Waste", 3rd Edition. All samples were submitted to Sequoia Analytical,Redwood City, <br /> California for analysis. Each sample was analyzed for total petroleum hydrocarbnns (TPH) in <br /> ;t accordance with EPA method 3510/8015 quantified against a diesel and gasoline standard and <br /> aromatic hydrocarbons;benzene,toluene,ethylbenzene,and total xylenes(BTEX)in accordance <br /> with EPA method 8020. In addition,samples were analyzed for total lead in accordance with <br /> i 2 <br /> EPA method 7421. <br /> l,w <br /> 4.2 ANALYTICAL CHEMISTRY RESULTS <br /> The analytical chemistry test results of the groundwater samples are summarized in Table 3. A <br /> M, summary of historical analytical results is presented in Table 4. The laboratory certificates of <br /> analysis are presented in Appendix C. The lead analytical results are reported as milligrams per, <br /> s liter (mg/I) which is equivalent to parts per million (ppm). All other analytical results are <br /> � i <br /> .t reported in micrograms per liter(ug/1) which is equivalent to parts per billion (ppb). <br /> I <br /> ! i i <br /> i In. <br />
