A Phase 1 ESA identifies Recognized Environmental Conditions (RECs), existing or potential contamination from current or historical site use. It is the standard due diligence product required by lenders (ASTM E1527) and is the first step in any environmental evaluation.

The Phase 1 ESA includes: site reconnaissance, historical records review (Sanborn maps, aerial photos, regulatory databases), interviews, and a written report. If RECs are identified, a Phase 2 (subsurface sampling) may be recommended, but the Phase 1 alone satisfies most lender and investor requirements for standard commercial acquisitions.

Primo partners with a qualified Environmental Professional to produce Phase 1 ESA reports. Contact us to discuss coordination as part of your due diligence scope.
