(NATER) , a Caiifornia <br /> Department of Health Services (DUHS) certified hazardous waste <br /> testing laboratory (Certificate 't1206) located at 625B Clyde <br /> Avenue, Mountain View, California. <br /> NATEX was instructed to test all of the samples for total <br /> petroleum hydrocarbons as gasoline (TPH-G) according to the <br /> guidelines established in thn Leaking Underground Fuel Tank <br /> (LUFT) field manual, and organic lead using DOHandrocedures. <br /> two <br /> NATER also tested all of the samples for BTXE, <br /> • samples with the highestotalconcentrations <br /> concentrationwas <br /> total <br /> lead. <br /> tested <br /> The sample with the highest <br /> for soluble lead. <br /> Since a solvent odor was detected during the drilling of <br /> boring B-6, the lanoratory was also instructed to test the two <br /> samples from this boring with the highest TPH-G concentrations <br /> for volatile organic compounds (VOCs) using EPA :Method 8240, and <br /> the sample with the highest TPH-G concentrations for extractable <br /> organic compounds (EOGs) using EPA Mr°�hod 8270. Additionally, <br /> sample B-6 @ 41' was tested for VOCs and EOGs. The results Of <br /> the testing are shown in Table 1. The laboratory reports are <br /> contained in P.ppendix C. <br /> 5.2 PLANKS <br /> The trip and equipment blanks were tested for TPH-G and BTXE <br /> (see Table 1 and Appendix C) . <br /> i . <br /> Project No. 1232 ..6_ <br /> a <br /> F,rV t11R0iViti1FA7TAL AUDI`f,INC.,, <br />
