SUMMARY AND CONCLUSIONS <br /> Based upon data collected during this monitoring event, AGE concludes the following <br /> • • Depth to ground water at the site averaged approximately 21 86 feet bsg on 29 November <br /> 2004 <br /> i <br /> Ground water elevation in the monitored area ranged from 9 88 feet to 9 99 feet below MSL <br /> ° Flow direction was inferred to be toward the northeast under a nearly flat gradient of <br /> approximately 0 001 ft/ft <br /> • None of the constituents of concern were detected in ground water samples from any of the <br /> three ground water monitoring wells for the second consecutive quarter <br /> • The lateral and vertical extents of dissolved petroleum hydrocarbon contamination have not <br /> yet been defined , <br /> _, I 5.6. RECOMMENDATIONS = { <br /> Based on the findings of the environmental activities recounted in this report,AGE recommends the <br /> continuation of the quarterly monitoring events The next event has been scheduled for / <br /> February`2005 A work plan is currently being prepared fo'rthe installation of additional ground <br /> 1 water monitoring wells at the site to confirm the lateral extents of dissolved petroleum hydrocarbons, <br /> and to verify'„and monitor the petroleum hydrocarbon-impacted ground water Once it is submitted <br /> to the EHD and approval is granted,AGE will acquire all necessary permits and begin the next phase <br /> of the investigation <br /> I, <br /> ' I Advanced GcoEnvironmental,Inc <br /> 1 � I <br /> I I I <br /> I E <br /> s <br />
