Phase I and Phase II Environmental Site Assessments

Aspen provides comprehensive Environmental Site Assessment (ESA) and due diligence services to identify potential or existing environmental liabilities. Our assessment services are fully compliant with current ASTM and All Appropriate Inquiry standards.


We firmly believe that the quality of any assessment ultimately depends on the qualifications, experience, and dedication of the investigation team. Toward that end, a senior Aspen professional oversees each assessment to ensure that potential environmental liabilities are well understood and accurately reflected.


Aspen staff have evaluated hundreds of properties, including former landfills, agricultural land, industrial facilities, urban redevelopment areas/Brownfields, residental and commercial properties. We understand that time is of the essence with many property transactions so we strive to provide a quality product on short notice.
