12 July 2002 AGE-NC Project No 98-0492 ' Page 3 of 3 The analytical results of ground water samples are summarized on Table 3 The laboratory reports ' (MAI Lab I D No 0205118-001 A through 020511$-003A), QA/QC report and chain-of-custody form are included in Appendix F ' 4.0. SUMMARY AND CONCLUSIONS ' Based on the data collected from the site, AGE concludes • The depth to ground water at the site on 8 May 200lwas between 20 25 to 21 50 feet below ' the well casing tops The prevailing ground water flow direction at the site was generally toward the northwest with a hydraulic gradient of 0 0006 feet/feet, consistent with the previously determined flow directions Ground water elevations at the site decreased an ' average 2 02 feet between the February 2002 and May 2002 sampling events • No analytes were detected at or above laboratory reporting limits in any of the soil or ground water samples analyzed 5.0. RECOMMENDATIONS Based on the findings of the environmental activities recounted in this report, AGE recommends • Continuation of quarterly monitoring of the ground water monitoring wells on-site The next monitoring event should be performed in August 2002 • No further action be taken at the site if analytes are not detected during the next two monitoring events 1 6 0. LIMITATIONS ' Our professional services were performed using that degree of care and skill ordinarily exercised by p environmental consultants practicing in this or similar localities The findings were based upon ' analytical results provided by an independent laboratory Evaluation of the hydrogeologic conditions at the site for the purpose of this investigation was made from a limited number of available data ' points(ground water samples)and subsurface conditions may vary away from these data points No other warranty, expressed or implied, is made as to the professional interpretations, opinions and recommendations contained in this report Advanced GeoEnviron.w.1,Inc 1
