i <br /> . t <br /> I' pads, fitted with plastic caps , sealed with black <br /> t electrical tape, labeled, placed on blue ice, and then <br /> transported under chain of custody for analysis for Total <br /> Petroleum Hydrocarbons as Gasoline (TPH-G) , benzene, <br /> toluene, total xylenes , and ethylbenzene (BTX&E) using EPA <br /> Methods 5030/8015 and 8020 , Total Lead (wet test)-, and ' <br /> Ethylene Dibromide (EDB) using EPA Method 504. <br /> j OBSERVATIONS <br /> j The 1,000 gallon., metal tank was found to be in good <br /> condition with no evidence of rusting !, or pitting noted. <br /> The native soils sampled from the floor of the tank pit <br /> { consisted of a medium brown silty clay. A strong <br /> hydrocarbon odor was noted in samples ',i#A1 and #A2 . No I <br /> discoloration or odor was noted in the dark brown organic <br /> clay soil in the area of samples #A3 and #A4. <br /> LABORATORY RESULTS ' <br /> Copies of all laboratory results as received from the <br /> certified hazardous waste analytical laboratory are <br /> enclosed as Appendix "A" and are summarized in .the <br /> following chart : <br /> !, NO.
