What is an Environmental Site Assessment?
A Phase I ESA (ASTM E1527-13) is used to gather information to identify Recognized Environmental Conditions (RECs) which may be associated with a subject property. It identifies actual or potential environmental contamination through records research, site inspection and interviews with owners and occupants which may impact the property value. It is conducted based upon the standards defined by the American Society for Testing and Materials (ASTM) and the Environmental Protection Agency (EPA) All Appropriate Inquiry.
If a potential contamination is found through the course of the Phase I Report, there may be a need to conduct a Phase II ESA (ASTM E1903) which will include substantial sampling and laboratory analysis to confirm the presence of hazardous material.
