sarnplc collected from MW-2 Benzene, xylenc, MTBF, tertiary butanol, and TAME were detected in the
<br /> groundwater ,arnple L011e,-ted from MW-2 (0 4, 1 5, 550, 72 and 3 6 µg/l, respectively) BTEX and TPH-G were

<br /> On December 31, 1997, Condor personnel were on site to conduct quarterly groundwater monitoring I aboratory
<br /> analyses of groundwater samples indicated that BTEX, TPH-G, and the selected gasoline oxygenates/additives
<br />' were not detected at or above the laboratory reported detection limits in the sample collected from MW-1
<br /> lAhanol, DWI-,, and hTBI, were not detected at or above the laboratory reported detection limits in any of the
<br /> groundwater tramples BTEX, TPH-G,and tertiary butanol were not detected at or above the laboratory reported
<br /> I detection limits in the sample collected from MW-3 MTBL and I AME were detected in the sample collected
<br /> from MW-3 l ow concentrations of B I EX constituents and TPH-G were detected in the samples collected from
<br /> MW-2 and MW-4 MTBE was detected in MW-4 M IBE, tertiary butanol, and TAMF were detected in MW-2
<br /> No floating product, sheen, or petroleum hydrocarbon odor was noted in the monitor wells Full evaluation of
<br /> intrinsic bioremediation parameters was not conducted because additional monitoring was necessary to evaluate
<br /> the potential for intrinsic bioremediation at the site
<br /> IGroundwater elevation measurements collected at the site monitor wells on December 31 1997, indicated that
<br /> the average depth from the ground surface to groundwater was approximately 4 feet fhe average depth to water
<br /> at the site decreased by approximately 2 feet between September 18, 1997 and December 31, 1997 Groundwater
