FINDINGS <br /> Ground water elevation in monitoring well MW-8 was determined from field data collected on <br />' 28 September 2004.Flow direction and gradient were unable to be determined because wells MW-1 <br /> through MW-7 were dry. The contaminant impact to ground water was quantified from laboratory <br /> analytical data. <br /> 3.1. GROUND WATER GRADIENT AND FLOW DIRECTION <br /> At the time of the September 2004 sampling event depth to ground water in well MW-8 was <br />' 62.75 feet below the top of the well casing; ground water elevation was calculated to be 34.69 feet <br /> below mean sea level (MSL) (Table 1). <br />' 3.2. ANALYTICAL RESULTS OF GROUND WATER SAMPLES <br />' No petroleum hydrocarbons were detected in the ground water sample from well MW-8. <br /> The analytical results of the water sample collected in September 2004 are summarized in Table 2. <br />' The laboratory report (CTEL Project No. CT214-0409198), quality assurance/quality control <br /> (QA/QC)report,and chain of custody form are included in Appendix C. Documents confirming the <br /> upload of laboratory electronic deliverable format (EDF) files and depth to ground water <br />' measurements to GeoTracker are included in Appendix D. <br />' 4.0. SUMMARY AND CONCLUSIONS <br /> Based on the data collected from the site, AGE finds: <br /> • <br />' Advanced GeoEnviromnental,Inc. <br />
