26, 1998 (Plate 3) Ground water flow direction appears to be <br /> generally northerly at an approximate hydraulic gradient of 0 005 <br /> Ground Water Elevations Static ground water elevations gauged on February 26, 1998 ranged <br /> from -7 27 feet to -8 43 feet below Mean Sea Level (Table 4) <br /> ANALYTICAL FINDINGS <br /> Hydrocarbon Distribution in Soil <br /> Boring CPT-1 was drilled near the southwestern corner of the site near the former UST located in <br /> this area of the site Soil samples from this boring were collected at depths of 40, 51, and 60 fbg <br /> The soil samples collected from 40 and 60 fbg did not contain detectable levels of TPPH, TEPH, <br /> benzene, and fuel oxygenates The soil sample collected at 51 fbg contained 1 6 ppm of TEPH <br /> TPPH, benzene, and fuel oxygenates were not detected in the soil sample from 51 fbg <br /> Boring CPT-2 was drilled adjacent to the former USTs located north of the bank building Soil <br /> samples from this boring were collected at depths of 40, 52, and 58 fbg The soil samples collected <br /> from depths of 40 and 58 fbg did not contain detectable levels of TPPH, TEPH, benzene, and fuel <br /> oxygenates The soil sample collected at 52 fbg contained 2 0 ppm of TEPH TPPH, benzene, and <br /> fuel oxygenates were not detected in the soil sample from 52 fbg <br /> Well boring S-1 was drilled in the eastern portion of the site The soil sample collected from S-1 at a <br /> depth of 15 fbg did not contain detectable levels of TPPH, benzene, or fuel oxygenates <br /> Well boring S-2 was drilled to the western portion of the site Three soil samples, collected at depths <br /> of 15, 25, and 30 fbg were analyzed from this boring The soil sample collected from 15 fbg did not <br /> contain detectable levels of TPPH, benzene, or fuel oxygenates The soil sample collected from 25 <br /> fbg contained 28 ppm TPPH, <0 025 ppm benzene, and 0 22 ppm MTBE The soil sample collected <br /> from 30 fbg contained 570 ppm TPPH, <0 50 ppm benzene, and <2 5 ppm MTBE <br /> Well boring S-3 was drilled along the northern property boundary, north/northeast of the former <br /> USTs The soil sample collected from 15 fbg did not contain detectable levels of TPPH, benzene, or <br /> fuel oxygenates <br /> Well boring S-4 was drilled in the southwestern corner of the site near CPT-1 and the former UST <br /> Soil samples collected from 10, 15, and 25 fbg did not contain detectable levels of TPPH, benzene, <br /> or fuel oxygenates <br /> 240-0943 5 <br />
