Phase I Environmental Site Assessment (ESA)
What is an ESA?
A Phase I Environmental Site Assessment (ESA) is a comprehensive investigation conducted in accordance with the ASTM E1527-13 standard to assess the environmental condition of a property. This assessment is typically performed prior to property transactions, real estate development, or financing to identify potential environmental liabilities and assess the risk of contamination.
Phase I Environmental Site Assessment (ESA) Overview
- Site Inspection
A qualified environmental professional visits the property to visually inspect the site and surrounding areas.
Historical data, aerial photographs, and other available records are reviewed to identify potential environmental concerns.
- Records Review
Historical and regulatory records are examined to identify any past uses or activities that may have contributed to soil or groundwater contamination.
- Interviews
Interviews are conducted with current and past property owners, occupants, and other relevant stakeholders to gather information on potential environmental concerns.
- Regulatory Research
- Report Preparation
A comprehensive Phase I ESA report is prepared, documenting the findings, observations, and conclusions of the assessment.
The report includes a determination of the Recognized Environmental Conditions (RECs) that may indicate potential environmental risks.
