t`° <br /> CAMBRIA <br /> Quarterly Sampling <br /> - - analyzed for Total Pur eable <br /> Monitoring Wells S 1 through S 6 were sampled andPetroleum g <br /> Hydrocarbons quantitated as gasoline (TPPH) and Total Extractable Petroleum <br /> Hydrocarbons as diesel (TEPH) according to EPA Method 8015 (Modified), and benzene, <br /> toluene, ethylbenzene, and xylenes (BTEX), and methyl-tertiary-butyl-ether (MTBE) <br /> according to EPA Method 8020. An EPA Method 8260 analysis for fuel oxygenates was <br /> I performed on the ground water sample from Well S-2. Additionally, a duplicate sample and <br /> an equipment blank were prepared and analyzed for quality control purposes. <br /> k Field':monitoring, data and chemical analytical data are summarized in Table 1. Blaine's <br /> ground water monitoring report is presented in Appendix A. <br /> I Conclusions " <br /> I <br /> E Ground water samples collected from the monitoring wells this quarter contained petroleum <br /> hydrocarbon concentrations similar to last quarter's concentrations. Ground water flow <br /> direction and gradient was consistent with the previous monitoring events findings. <br /> i <br /> I <br /> Recommendations <br /> Ground water monitoring and sampling will continue on a quarterly basis for this site. <br /> If you have any questions regarding the contents of this document, please call. <br /> I, Sincerely, <br /> Cambria Environmental Technology, Inc. <br /> i <br /> I � <br /> Joe W.
