Phase 1 Environmental Site Assessment – ASTM E1527-13


Phase I Environmental Site Assessments (ESA)

A Phase I ESA is used to identify actual and potential environmental concerns and contamination at a Site which may impact the property value or affect claim to an “innocent land owner” exemption following acquisition. Environmental Site Assessments are performed in accordance with the most recent American Society for Testing and Materials (ASTM) Standard E 1527-13, Standard Practice for Environmental Site Assessment. The ASTM E1527-13 Standard is the most comprehesive and widely accepted standard for conducting Environmental Site Assessments. Financial institutions frequently require that a Phase I ESA be conducted for due dilligence. Overlooking environmental concerns can cost you substantial future environmental expenditures, even if you did not create or contribute to the contamination.
