Who Performs a Phase 1 Environmental Site Assessment
A Phase 1 Environmental Site Assessment is performed by a qualified environmental professional, often a licensed environmental engineer or geologist, who reviews the property's history and current conditions to identify potential contamination. This assessment is the first step in determining whether a site poses environmental liabilities before a transaction or development proceeds.

Qualifications Required
Professionals conducting Phase 1 assessments must meet specific standards, typically outlined by ASTM International (ASTM E1527-21). The assessor must be an environmental professional with education and experience in recognizing Recognized Environmental Conditions (RECs). They must also demonstrate knowledge of state and federal environmental regulations.
The Assessment Process
The process involves a thorough review of regulatory databases, historical records, and site reconnaissance. The professional examines prior land uses, building materials, and surrounding properties to identify potential sources of contamination. This non-intrusive investigation does not involve soil or groundwater sampling.
Why Professional Evaluation Matters
Hiring a qualified professional ensures compliance with the All Appropriate Inquiries (AAI) rule, which protects property buyers from liability under CERCLA. An improperly conducted assessment can invalidate the AAI defense, leaving buyers responsible for cleanup costs. The report produced serves as a critical due diligence document for lenders and investors.
Selecting the Right Assessor
When selecting a provider, consider their familiarity with local regulations and site history. The assessor should provide a comprehensive report that includes a detailed analysis of the property's historical uses and a clear opinion on recognized environmental conditions. Look for professionals with credentials such as Certified Environmental Professional (CEP) or relevant state licensure.
