Environmental Site Assessments
An environmental site assessment (ESA) is the practice of identifying "recognized environmental conditions" related to a parcel of property through appropriate inquiry into the previous ownership and uses of the property consistent with good commercial and customary practice. The American Society for Testing and Materials (ASTM) standardized this process under ASTM E1527-05, "Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process." ASTM E1527-05 allows the user to perform an acceptable level of environmental due diligence and satisfy one of the requirements to qualify for the "innocent landowner defense" under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA).
