The three water samples were analyzed for total petroleum <br /> hydrocarbons (TPH) and purgeable aromatic hydrocarbons (BTE&X) in <br /> accordance with the DHS Method (801-m) and EPA Method 80 <br /> Contaminated water developed from purging the monitoring wells was <br /> stored in 55 gallon drums�n site. The drums were labeled with the <br />' site location, date of accumulation, contents, and the consultants <br /> name and phone number. <br />' A survey to locate water wells within a 2 , 000 feet radius of the <br /> subject site was conducted at the California Department of Water <br /> Resources. It has been noted that the ground water gradient beneath <br />' the subject site has shown seasonal reversals. We believe that the <br /> cause of this is probably a pumping well that is located to the <br /> north of the subject property. <br />' FINDINGS <br /> Ground water was measured at a depth of approximately 82 to 83 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 north (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/1 in the water <br /> samples from MW2 and MW3 (Table 2) . BTE&X were not detected, at a <br /> detection limit of . 3 gg/l to . 6 gg/l , in the water samples from <br /> 1 MW2 and MW3 (Table 2) . <br /> The laboratory analysis quality control/quality assurance data, <br /> /laboratory state certification, and chain of custody are attached. <br /> Three ground water wells were located within a 2 , 000 foot radius <br /> of the subject site (Figure 3) .
