= a 19 April 1999 AGE-NC Project No 960229 Page 5 of 5 • Dissolved petroleum hydrocarbons have been detected during two of three ground water monitoring events performed at downgradierit well MW-I OB (screened 50 to 55 feet bsg), therefore, the dissolved petroleum hydrocarbon plume appears to have migrated up to MW- 10B ' 50. RECOMMENDATIONS Based upon data collected during April 1999, AGE recommends • Preparation of a Corrective Action Plan (CAP), the CAP should include results of any required feasibility studies to determine remediation alternatives for the site A receptor survey should also be performed to locate potential receptors within 2,000 feet of the site, results of the receptor survey should be included in the CAP • Continued quarteily ground water monitoring and sampling should be performed at the site in July 1999 • Anangernents should be made to dispose of all stockpiled soil at the site by hauling off-site to a suitable hazardous waste facility (r e BFI Landfill) 60 LIMITATIONS Our professional services were performed using that degiee of care and skill ordinarily exercised by environmental consultants practicing in this of similar localities The findings were based rmmnly upon analytical results provided by an independent laboratory Evaluations of the geologic/hydro- geologic conditions at the site for the purpose of this investigation are made from a limited number of available data points (e g ground water samples), and subsurface conditions may vary away from these data points No other warranty, expressed of implied, is made as to the professional recommendations contained in this report Advanced GeoEnN,ronmentaf,Inc
