Recognized Environmental Condition (REC)
The presence or likely presence of hazardous substances or petroleum products on a property, identified during a Phase I Environmental Site Assessment.
The Full Picture
A Recognized Environmental Condition (REC) is the key finding category in a Phase I Environmental Site Assessment. ASTM E1527-21 defines a REC as 'the presence or likely presence of any hazardous substances or petroleum products in, on, or at a property: (1) due to a release to the environment; (2) under conditions indicative of a release to the environment; or (3) under conditions that pose a material threat of a future release to the environment.' RECs are distinguished from de minimis conditions (minor issues not likely to affect property use), controlled RECs (identified contamination being managed by a regulatory program), and historical RECs (past contamination that has been remediated to regulatory satisfaction).
Why It Matters
Why field professionals need to document this
RECs are the findings that make or break commercial real estate deals. A Phase I with no RECs provides the buyer with 'innocent landowner' protection under CERCLA (Superfund). RECs trigger Phase II investigations (actual sampling and testing), which can add weeks and thousands of dollars to the transaction timeline. For environmental consultants, the professional judgment involved in identifying and categorizing RECs is the highest-value part of the report — and the most legally consequential.

How this shows up in findings
Here's how a recognized environmental condition (rec) finding looks in a professional field report generated by ReportWalk:
REC: Former dry cleaner on adjacent property, groundwater flow direction toward subject — chlorinated solvent contamination possible
HREC: Underground storage tank removed in 2015, closure letter received from state DEQ — no further action required
De minimis: Small area of stained concrete in garage — consistent with residential vehicle maintenance, not a REC
