Frequent Questions

What is a Phase One assessment, and do we need one?

A Phase I site assessments includes:

  • an inspection of the property;
  • a review of pertinent records for evidence of current and past use of the property and adjacent properties;
  • interviews with current owners and occupants as well as local government officials;
  • evaluation of information gathered and development of a report; and,
  • in some cases, samples are collected of building materials to determine if PCBs, asbestos, or lead are present.

It is called a Phase I assessment because it is conducted in compliance with ASTM E1527-00 Standard Practice for Environmental Site Assessments: Phase 1 Environmental Site Assessment Process. A Phase II assessment entails additional sampling to confirm contamination or to determine the nature and extent of contamination.
