18 September 1998 <br /> AGE-NC Project No 96-0254 <br /> Page 7 of 8 <br /> I A ground water sample was collected from well 2420 Grant Lane Road Well MW-3 on 30 January <br /> 1998 No TPH, BTEX or fuel oxygenates were detected in this sample The laboratory report for <br /> 2420 Grant Lane Road Well MW-3 is included in the Quarterly Report -January 1998 dated 02 <br /> April 1998, for Grant Lane Gas and Food <br /> I4.0. SUMMARY AND CONCLUSIONS <br /> The following conclusions were drawn from the iesults of this investigation <br /> • Ground water at the site was encountered at a depth of approximately 5 feet bsg The <br /> prevailing ground water flow direction at the site is generally northward <br /> • The most intensely hydrocarbon-impacted soil was encountered in the area of the former <br /> I USTs Hydrocarbon-impacted soil was not observed in the soil borings established on the <br /> exterior of the inferred dissolved hydrocarbon plume <br /> • Dissolved petroleum hydrocarbons and BTEX compounds were detected only in wells MW- <br /> 1A and MW-1B Therefore, the lateral extent of the dissolved phase plume is limited to the <br /> area of MW-IA and MW-1B <br />' • Oxygenated compounds were not detected in the analyzed soil and ground water samples <br /> collected from the site and from off-site <br /> 5.0. RECOMMENDATIONS <br /> IBased on the results of this investigation, AGE recommends <br /> • A quarterly monitoring event should be scheduled for September 1998 and should be <br /> conducted concurrently with the monitoring event for the 2420 Grant Line Road site <br /> I <br />• <br /> Advanced GeoEnviron mental Inc <br />
