C A M B R I A <br /> • Wells S-1 and S-3 contained DIPE concentrations of 41 3 and 186 ppb, respectively <br /> Methanol was not detected in any of the wells with the exception of Well S-1, which <br /> contained a concentration of 5,600 ppb <br /> Quarterly Sampling <br /> Monitoring Wells S-1 through S-6 were sampled and analyzed for Total Purgeable Petroleum <br /> Hydrocarbons as gasoline (TPPH), Total Extractable Petroleum Hydrocarbons as diesel <br /> (TEPH) and Industrial Solvents (Methanol) according to EPA Method 8015 (Modified), <br /> benzene, toluene, ethylbenzene, xylenes (BTEX), and methyl-tertiary-butyl-ether (MTBE) <br /> according to EPA Method 8020 In addition, Volatile Organic Compounds (fuel oxygenates) <br /> by EPA Method 8260B were sampled <br /> Field monitoring data and chemical analytical data are presented in a summary table in <br /> Blaine's groundwater monitoring report (Appendix A) <br /> Conclusions <br /> Groundwater samples collected from the monitoring wells this quarter contained petroleum <br /> hydrocarbon concentrations similar to previous quarters' concentrations Groundwater flow <br /> direction and gradient was found to be consistent with the previous monitoring event's <br /> findings <br /> Recommendations <br /> Groundwater 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 Joe Neely at <br /> (707) 935-4854 <br /> i <br /> Sincerely, <br /> C bria E vtronmental Techno <br /> Q�pF ES S/4 <br /> lumm s <br /> S ie tco <br /> Uj No C 7 49 M <br /> i L May dUP <br /> Senor Geo ogi �r <br /> RG #6717 `PTF ClV1V�O���� <br /> 4F CALF <br /> 241-0943 2 <br />
