Because the TPH(gasoline) and BTEX results.are similar -to those from <br /> previous sampling .events, the slightly elevated=temperature (11°C) does not <br /> appear to have had an.effect on the integrity_of'the.samples; however; we have <br /> qualified these. results :as.estimated (Table.4-3 and-4-4). Subsequent monitoring <br /> events will verify -the. representativeness of -these results. . The other cooler; <br /> which contained liter bottles for'TPH(diesel)-.analysis was within the allowable <br /> temperature range (5°C):' - <br /> Please feel free to contact me at (510) 946-0455 if'you have any comments or <br /> questions. <br /> i Sincerely, p . <br /> ERM-WEST, INC: �yA' QU���(�� <br /> eW <br /> Jill A.
