Contaminated water developed from developing and purging the <br /> monitoring wells was stored in 55-gallon drums on site. The drums <br />' were labeled with the site location, date of accumulation, <br /> contents, and the consultants name and phone number. <br />' �IlYGS <br /> The borings encountered a layer of dark grayish brown to black sand <br /> to a depth of approximately four feet and intermittent layers of <br /> silt, very fine sand and course sand to total depth (Boring Logs) . <br />' Ground-water was first encountered at a depth of approximately 65 <br /> to 70 feet (Boring Logs) . <br /> Hydrocarbon odors were noted in borings B4, B6, and B7 . High levels <br />' of benzene were also detected with the TIP and OVM in borings B4, <br /> B6, and B7 (Boring Logs) . <br />' High levels of TPH was detected in soil samples near the capillary <br /> fringe in boring B4 (Table 1) . TPH was also detected in every soil <br /> sample analyzed in boring B7 (Table 1) . TPH was not detected in the <br />' soil samples obtained from borings B5, B6, and B8 at a detection <br /> limit of . 5 mg/Kg (Table 1) . <br /> BTE&X were detected in the soil sample with the highest <br /> concentration of TPH from boring B4 and B7 (Table 1) . The soil <br /> samples from B5, B6, and B7 were not analyzed for BTE&X. <br />' Ground-water was measured at a depth of approximately 74 feet in <br /> the monitoring wells. The relative casing elevations, depth to <br /> water and piezometric surface determined from the monitoring well <br /> measurements are recorded in Table 2 . The ground water gradient is <br /> generally flat, less than . 01, to the southwest (Figure 2) . <br /> TPH and BTE&X were detected in each of the ground-water samples and <br />' in the trip blank (Table 3) . The laboratory reported that the trip <br /> blank and the samples obtained from MW2 , MW3 , MW5, and MW6 had <br /> hydrocarbon patterns not consistent with the standard gasoline fuel <br />' pattern (Table 3) . BTE&X was not detected in the trip blank at a <br /> detection limit of 1 µg/l. <br /> The laboratory analysis quality control/quality assurance data, <br /> laboratory state certification, and chain of custody are attached. <br /> 1 <br /> U-HAUL 12701 N WILSON WAY <br /> MIS-93-III I U-HAUL QM4 (5D5020 2) <br /> 1 14 JUNE 1993 5 <br />
