It includes:
• Site inspection and reconnaissance of adjacent surroundings
• Review of historical/environmental records and land-use
• Review of petroleum product storage, spills and disposal records
• File review of local, state and regional agencies
• Interview with owners, occupants and property managers
• Written report with findings, conclusions and recommendations

Phase II Site Assessment
Required when a Recognized Environmental Condition (REC) is found during the Phase One environmental assessment process.
The scope of a Phase ll ESA may vary significantly based on the Phase One findings and other objectives dictated by the client. In general, a Phase II ESA consists of collecting soil samples to find out the level of chemical or metal contamination. It could also include groundwater and surface water sampling and analysis.
