Phase Two Environmental Assessment in Dallas, TX

A Phase Two ESA includes soil borings, groundwater sampling, and soil vapor testing at targeted locations on your Dallas property. Samples go to a certified lab and are analyzed for contaminants such as VOCs, SVOCs, and RCRA metals, with results compared to TCEQ Protective Concentration Levels.

A Phase Two ESA is needed when a Phase One report identifies a Recognized Environmental Condition (REC) that requires physical testing to resolve. Common triggers in Dallas include properties with prior use as gas stations, auto repair shops, dry cleaners, or other industrial operations.

A Phase One ESA relies on records review and a site walk to identify potential environmental concerns, but it does not include any sampling. A Phase Two ESA follows up by collecting actual soil, groundwater, and vapor samples to confirm whether contamination is present at a Dallas property.

The buyer, lender, or developer most often pays for a Phase Two ESA as part of due diligence on a Dallas property. Payment is negotiable between buyer and seller, and some deals split the cost or credit it at closing depending on who requested the assessment.

If lab results show contamination above TCEQ Protective Concentration Levels, the next step is typically a formal remediation pathway, which may involve reporting to the TCEQ and enrolling in a state program such as the Voluntary Cleanup Program or the Innocent Owner/Operator Program. From there, options can include soil excavation, groundwater treatment, or other site-specific cleanup measures depending on the type and extent of contamination found.
