-WEGE- <br /> DISCUSSION <br /> A ground water contour map was developed using the current well <br /> data and indicates an apparent flow direction to the northeast. <br /> This flow direction coincides with the flow directions noted in <br /> earlier reports presented by WEGE, see FIGURES 4A thru 4I. <br /> The analytical laboratory results indicate that TPH (Gasoline <br /> range) and BTEX (Volitile Aromatic hydrocarbons) concentrations <br /> in MW1, MW2 and MW3 are non detect (ND) . <br /> With these factors in mind (non detect TPH & ZTEX on this <br /> sampling period and below reportable limits (BRL) for MW1, MW2 and <br /> MW3 on previous samplings) "site closure" should be considered at <br /> this time. The analytical results are presented in WEGE: TABLE 2, <br /> and the laboratory report is included in Appendix A. <br /> CONCLUSIONS <br /> 1. The ground water flow direction is presently in 1 <br /> a northeasterly direction. <br /> 2. Laboratory analysis was non detect on TPH & BTEX for MW1, MW2 <br /> -- and MW3. <br /> i <br /> RECOMMENDATIONS <br /> 1 . Based upon the above conclusions this site should be <br /> considered as "closed" for DESERT PETROLEUM. <br /> 2. Once site closure is granted, the existing onsite monitor <br /> wells should be destroyed, to prevent any risk to the ground <br /> water from ongoing retail of gasoline at the present service <br /> station facility on site. <br /> LIMITATIONS lit <br /> The discussion and conclusions presented in this report are based <br /> on the following. <br /> 1 . The observations and data collected by field personnel. <br /> 2 <br />
