The phases of EDD

The environmental due diligence (EDD) is separated in two parts:

EDD phase I

A non-intrusive assessment aimed at identifying potential environmental liabilities.

Typically includes:

• Review of historical land use and records.
• Regulatory and permit review.
• Site walkover and visual inspection.
• Interviews with owners or operators.

Purpose: To identify recognized environmental conditions (RECs) and determine whether further investigation is needed.

EDD phase II

An intrusive investigation conducted if Phase I identifies potential risks.

Typically includes:

• Soil, groundwater, or building material sampling.
• Laboratory analysis.
• Delineation of contamination.
• Risk and cost estimation for remediation.

Purpose: To confirm the presence, extent, and severity of contamination and assess environmental and financial risk.
