GEOTHINK conducted a Phase II Environmental Site Assessment at a gas station in Pontiac, Illinois yesterday.
Based on the REC findings and recommendations of the Phase I ESA report, a Phase II assessment may include physical sampling of building materials for lead, asbestos or mold testing; and/or subsurface investigation using and borings and wells to collect representative soils, groundwater or soil gas samples for lab testing for potential contaminants of concern (COCs) with the results compared to individual State cleanup limits. Phase II report identifies location(s) of testing samples contaminants above applicable regulatory limits, possible contaminant source(s) i.e. drums, USTs (underground storage tanks), ASTs (above ground storage tanks), floor drains, utility conduits and/or building materials; and provides recommendations for further investigation or mitigation/remediation of problem areas, or testing results did not identify contamination issues warranting further corrective actions.
