P g P <br /> monitoring events Concentrations in MW-1 showed the lowest levels yet recorded in <br /> samples from that well Concentrations in MW-2 showed a significant increase from the past <br /> monitoring event Floating product was not observed in this well during the monitoring <br /> event however September of 1996 is when floating product was first observed in MW-2 <br /> Concentrations in MW-4 stayed relatively consistent with the past monitoring event MW-5 <br /> and MW-102 showed decreases since the May 1997 event <br /> MTBE was detected in MW-I and MW-5, both wells were just above detection limits None <br /> of the other fuel oxygenates were detected in water samples from any of the wells <br /> The three domestic wells associated with the site were all non-detect for BTEX, TPH-G and <br /> the oxygenates <br /> 3.0 CONCLUSIONS AND RECOMMENDATIONS <br /> The followingconclusions have been drawn regarding the status of the groundwater at this <br /> g g <br /> Isite and recommendations for future work <br /> Conclusions <br /> 1 Petroleum hydrocarbons are present in five of the nine monitoring wells <br /> 2 The shallow water table groundwater plume is laterally defined except to the west <br /> 3 Free floating gasoline was not present in MW-2 in September 1997 <br />
