The 6" extraction well was not sampled <br /> at this time. <br /> Linda A. Turkatte, Environmental Health Specialist for the <br /> San Joaquin County Public Health Services Department, was on <br /> site to observe the December sampling activities. <br /> The groundwater samples were analyzed by a California certified <br /> laboratory (Sherwood Labs Corp: ) using EPA method 602 for BTEX <br /> analysis, with a detection limit of 0. 3 ug/Kg, and EPA method <br /> 5030/Mod. 8015 for TPH-Gasoline analysis, with a detection limit <br />' of 50 .0 ug/L (Table 6) . <br /> TABLE 6 <br /> GROUNDWATER SAMPLE ANALYSES <br /> (12-9-91) <br /> SAMPLE LOCATION/CONCENTRATION <br /> NW-6 NW-7 MW-8 MW-9 MW-10 NW-11 MW-12 NW-13 BLANK <br /> (ug/L) (ug/L) (ug/L) (ug/L) (ug/L) (ug/L) (ug/L) (ug/L) (ug/L) <br /> B ND ND ND ND ND ND ND ND ND <br /> T ND ND ND ND ND ND ND ND ND <br /> E ND ND ND 8. 0 ND ND ND ND ND <br /> X ND ND ND 12. 0 ND ND ND ND ND <br /> TPH-G ND ND ND 0. 7 ND ND ND ND ND <br /> NOTE: ND Represents none detected <br />' STE Project No. 4001 <br /> Page 4 <br />
