What Is a Phase 1 Environmental Site Assessment?

A Phase 1 Environmental Site Assessment, commonly known as a Phase 1 ESA, is the first step in identifying possible environmental contamination or risks associated with a property. It’s a non-invasive study that relies on research, inspections, and interviews rather than physical testing.

It’s the first step in environmental due diligence and follows the ASTM E1527-21 standard.

Here’s what it typically includes:

  • Historical research: Reviewing property deeds, maps, aerial photos, and past land use
  • Site inspection: Checking for visible contamination, tanks, or hazardous materials
  • Interviews: Speaking with current or former owners, tenants, or local officials
  • Comprehensive report: Outlining findings, risks, and next steps

A properly conducted Phase 1 ESA helps determine whether further testing (such as a Phase 2 ESA) is needed.

At 4WPI, our certified inspectors provide thorough, compliant Phase 1 Environmental Inspections for commercial, residential, and industrial properties.
