1 �I <br /> Contaminated water developed from purging the monitoring wells was <br /> stored in 55 gallon drums on site. The drums were labeled with the <br />' site location, date of accumulation, contents, and the consultants <br /> name and phone number. <br />' FINDINGS <br /> Ground water was measured at a depth of approximately 74 to 75 feet <br /> in 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 1. The ground water gradient is <br />' generally flat, less than . 001, to the west-southwest (Figure 2) . <br /> TPH and BTE&X were detected in the water sample from MW1 (Table 2) . <br /> TPH was not detected, at a detection limit of .5 mg/l in the water - <br />' samples from MW2 and MW3 (Table 2) . With the exception of .3 µg/1 <br /> of benzene in MW2 , BTE&X were not detected, at a detection limit of <br /> . 3 gg/1 to . 6 µg/l, in the remaining water samples (MW2 and MW3) <br />' (Table 2) . <br /> The laboratory analysis quality control/quality assurance data, <br /> laboratory state certification, and chain of custody are attached. <br /> CONCLUSIONS <br /> The ground water gradient vector has changed from a northerly <br /> direction to the west-southwest (Figure 2) . The ground water <br /> gradient has remained generally flat, less than . 01. <br /> Monitoring well 2 shows a decrease in TPH and BTE&X concentrations <br />' over time. The decrease in TPH and BTE&X concentrations over time <br /> is consistent with a natural degradation of these contaminants over <br /> time. However, TPH and BTE&X concentrations in monitoring wells MW1 <br /> and MW3 are still fluctuating. <br /> 1 The limits of the ground water contaminant and the soil contaminant <br /> plumes have not been determined. <br /> 1 i <br /> i <br /> U-HAUL 12701 N WILSON WAY <br /> bUB-93-II I U-HAUL QM3 (SD5020 2) <br /> 9 APRIL 1993 4 <br />
