Phase I and II Site Assessment

Phase I Environmental Site Assessments (ESA's) have been used as a due diligence tool in real estate transactions for many years. The information gained by conducting ESA's should identify potential environmental issues with past/current site operations that may impact or have the likelihood to impact the environmental condition of a real estate parcel(s) before the property is purchased. The American Society for Testing and Materials (ASTM) standard ASTM E-1527-05 has been used as the definitive "template" as to how ESA's should be conducted and reported.

Where Phase I ESAs are an investigation of existing data regarding a particular site, Phase II Environmental Site Assessments/Investigations include generating site-specific data by collecting samples, conducting on-site testing and recording observations in regard to site conditions. The data collected are used in the decision making process to collect additional data, evaluate remedial options or seek regulatory site closure. The data collected may also be used to identify contaminant source areas, potential off-site sources and contaminant transport mechanisms.
