Our Environmental Consulting Expertise
Phase I Environmental Site Assessments (ASTM E1527-05)
We conduct comprehensive historical research, regulatory database reviews, site inspections, and interviews to identify Recognized Environmental Conditions (RECs). Ideal for real estate transactions, financing, and compliance needs.
Phase II Environmental Site Assessments
If a Phase I ESA reveals potential concerns, our Phase II assessments provide targeted sampling of soil, groundwater, and building materials to characterize contamination and quantify risk.
Environmental Transaction Screens (ASTM E1528-06)
A streamlined option for lower-risk properties, offering faster, cost-effective screening while still providing essential environmental insight.
Vapor Intrusion Assessments (ASTM E2600-08)
We assess the potential for vapors from subsurface contamination to migrate into indoor air and provide mitigation strategies if VOC or gas levels exceed safe limits.

Frequently Asked Questions
What’s the difference between a Phase I and Phase II ESA?
A Phase I ESA is a preliminary non-invasive investigation to flag potential environmental issues; a Phase II ESA involves sampling and analysis to confirm or rule out contamination.
When is vapor intrusion study required?
Vapor intrusion assessment is needed when contamination is detected in the subsurface and there is a risk that gases or volatile compounds may migrate into occupied buildings.
How long does a Phase I ESA take?
Typically 2–4 weeks, depending on site complexity, data availability, and regulatory reviews.
