Book a consultation →A Phase I ESA is a non-intrusive review designed to identify Recognized Environmental Conditions on a property. It includes historical research, regulatory database review, site reconnaissance, interviews, and a written report aligned with ASTM E1527-21.
Monitoring is generally required when contaminants are detected above screening levels or an active remediation system is operating. Programs commonly begin quarterly and become less frequent as closure criteria are approached.
Surveys are commonly required before renovation, demolition, or significant disturbance of older structures. Our certified inspectors provide sampling, laboratory analysis, and abatement recommendations.
We combine a building walkthrough and occupant interviews with monitoring for VOCs, carbon dioxide, particulates, humidity, and mold. Lab-validated results are delivered with a remediation protocol and clearance testing plan.
Yes. We support permit applications, emissions inventories, greenhouse-gas reporting, dispersion modeling, and direct coordination with regulatory agencies.
Regional field crews can often mobilize within two to four hours with containment equipment, sampling gear, and regulatory communication support.
Well-defined assessments and surveys are typically fixed fee. Investigations and remediation with evolving conditions may use time-and-materials pricing with transparent rates and a not-to-exceed cap.
