Frequently Asked Questions

A Phase 1 Environmental Site Assessment (ESA) is a report that summarizes the results of an environmental investigation of a property. It identifies potential environmental hazards or liabilities associated with a property and provides recommendations for further investigation or mitigation. The investigation typically includes a review of the historical and current uses of the site, an evaluation of potential environmental hazards, and a review of any previous environmental investigations or cleanups. The report is commonly used as a due diligence tool for property transactions, lending, and insurance purposes.


A Phase 1 Environmental Site Assessment (ESA) report outlines the findings of an environmental study conducted on a site. Typically, the scope of the study encompasses a review of the site’s historical and present usage, an appraisal of possible environmental dangers, and a review of any past environmental investigations or cleanups undertaken on the site. During a typical Phase 1 ESA, the following specific site locations are frequently investigated:

  • The property itself as well as any neighboring properties that have the potential to affect the site.
  • The property’s past and present usage, including any industrial, commercial, or residential purposes.
  • Any known or prospective contamination sources, including underground storage tanks, hazardous waste disposal places, and spills.
  • Wetlands and other protected natural resources that may exist on or near the property.
  • Any potential historical or cultural resources on or around the site.
  • Any environmental studies or cleanups undertaken on the site or nearby properties.
  • Any relevant regulatory information or enforcement actions.
  • The Phase 1 Environmental Site Assessment report should also contain any suggestions for additional site inquiry or testing, as well as any possible liabilities or risks linked with the property.
