GCE was chosen to complete Phase I, Phase II Environmental Site Assessments (ESA), Remediation, Underground Injection Well Closure, Sanitary Closure, Sewer Connection and Underground Oil Tank /Hydraulic Lift Removal works on behalf of a confidential Long Island developer. With Phase I and Phase II it was determined through subsurface soil/groundwater sampling and substructure investigation, if potential contamination associated with the areas of environmental concern identified in the previous Phase I Environmental Site Assessment has environmentally impacted the Site.
Based on the findings, vertical and horizontal delineation of subsurface petroleum contamination impacted soil and vertical delineation of subsurface drainage structure were determined and all contaminated soil was removed from the Site. In addition, on-site former sanitary system was closed, sewer was connected to the building. Underground injection well was closed, all on-site drywells were remediated. The 4-4,000-gallon gasoline, 1-550-gallon #2 fuel oil Underground Storage Tanks and 2 Underground Hydraulic Lifts were removed from the site. All contaminated soil found during site investigation associated former tanks were excavated and removed from the Site. The environmental conditions at the property have been evaluated to the applicable regulatory agency and found in compliance with the department’s requirements.
