Figure 4 shows the water-level <br /> data collected and interpreted contour lines. <br />' 7.0 LABORATORY ANALYSES <br /> The samples were sent to McCampbell Analytical Inc . of Pacheco, <br /> California, a state-certified laboratory, and analyzed for <br />' TPHg using EPA Method 5030/GCFID; <br /> • BTEX and MTBE using EPA Method 8020/8260 , and <br /> • TPHd using EPA Method 8015M, <br /> The samples were analyzed on a normal 5-day turnaround basis <br /> 7.1 Laboratory Analytical Results <br /> The laboratory analytical results are summarized in Table 1 and <br /> Figure 3 Laboratory certificates are included in Appendix A <br />' The results are as follows: <br /> Analysis of groundwater samples indicated that <br /> o TPHg concentrations were less than 50 . 0 gg/l (not detected) <br /> o Benzene concentrations were less than 0 5 4g/l (not <br />' detected) <br /> o Toluene concentrations were less than 0 5 Ag/1 (not <br />' detected) <br /> o Ethylbenzene concentrations were less than 0 . 5 4g/1 (not <br />' detected) . <br /> o Xylenes concentrations were less than 0 5 4g/l (not <br /> detected) <br /> o MTBE concentrations were less than 1 0 4g/l (not detected) . <br />' o TPHd concentrations ranged from less than. 50 . 0 4g/l (not <br /> detected) to 240 qg/l <br />' 8.0 DISCUSSION <br />' Groundwater samples were collected from wells MW-1, MW-2 , and <br /> MW-3 Groundwater was encountered at a depth of approximately 14 <br /> feet bgs Mapping and analysis of the groundwater elevation data <br /> 4 <br /> O <br />
