i analytical results of these soil samples, approximately 16o cubic <br /> 2 yards of additional soil was removed from the vicinity of the <br /> 3 former UST. <br /> 4 b. Qctober 1989 Water Sa=linq Despite evidence <br /> 5 that contaminated soil had been removed, the Health Department <br /> 6 requested an additional survey of all wells in a 2, 000 foot <br /> 7 radius of the UST location. The data reported from that sampling <br /> 8 event showed no concentrations of concern.- Only one sample from <br /> 9 Well 5298 (reportedly located upgradient, i.e, northeast, of the <br /> 10 UST excavation) contained benzene at 0-.00`01 ppm. <br /> 11 C. January 1990 Soil Sampling-. Following the over <br /> 12 excavation of the tank grave, six additional soil samples were <br /> 13 collected from the base and sdewa.Ils of the excavation on <br /> 14 January 9, 1990. Analytical results for these samples did not <br /> 15 reveal contamination at levels of concern. The only detected <br /> 16 soil contaminants (toluene at .006 ppm, total xylenes at 0.091 <br /> 17 ppm, and TPH as diesel [TPHd] at 15 ppm were (individually and in <br /> 18 the aggregate) were substantially below the 100-300 ppm standard <br /> 19 typically applied in determining the need for further soil <br /> 20 remediation and do not otherwise warrant further investigation. <br /> 21 It is also notable that neither benzene nor ethyl benzene were <br /> 22 detected in any of the soil samples collected during the <br /> 23excavation activities. <br /> 24 d. January 1990 Water Sa=ling. In January 1990 the <br /> 25 groundwater in four existing agricultural supply wells was <br /> 26 sampled. The results of the January 1990 sampling of the <br /> 27 agricultural supply wells also failed to reveal contamination at <br /> 2s any level warranting further investigation.
