Phase II ESAs are conducted when “recognized environmental conditions” (RECs) are identified during a Transaction Screen Process or Phase I ESA and further investigation is warranted to determine the potential liability and risk associated with the condition. The Phase II ESA is a more detailed investigation to determine the nature and extent of soil and groundwater contamination through sampling and analysis methods.
To conduct a Phase II ESA and assess the RECs identified on a property, a sampling plan is prepared describing the rationale for the proposed sample locations, collection methods, and laboratory analysis. The final sample results are evaluated by the consultant, a draft Phase II ESA report is completed, conclusions are discussed with the client and recommendations are proposed. An initial sampling event may not provide enough data to develop a conceptual model of the site and a more comprehensive assessment may be required.
