Environmental Site Assessments are a risk analysis tool that minimizes environmental liability exposure to financial institutions, land developers, and real estate brokers.

TSI’s repertoire of environmental services not only identifies any environmental concerns that may exist for a particular property, but can also lead to solutions that minimize the risk to the client and maintain the integrity of a property’s value.

The new Brownfields Law provides contamination liability protection to landowners, but only if they conduct a level of site assessment meeting the new law’s definition of “All Appropriate Inquiries” (AAI.) Only recognized Environmental Professionals (EPs) will be allowed to conduct Environmental Site Assessments (ESAs).

Terrain Solutions Environmental Professionals (EPs) meet EPA criteria and carefully adhere to AAI standards. We provide you with a thorough report on potential contamination issues in given real estate ventures.

We pride ourselves on being both reasonable and professional, providing our clients with true value for their investment.

ESAs are conducted in three phases:

  • Phase I: ASTM 1527-00 & AAI/ASTM 1527-05: Identification of potential environmental hazards on a given site. Includes a regulatory records search, interviews, site reconnaissance and a written report. The AAI assessment meets Brownfields Law All Appropriate Inquiry requirements.

  • Phase II: Confirms the presence or absence of contaminants on a site.

  • Phase III: Determination of contaminants and extent of damage and can include a site remediation plan.
