Phase II Environmental Site Assessment (ESA)

Confirm or Rule Out Contamination with Targeted Site Testing

When a Phase I ESA reveals a potential environmental concern, a Phase II Environmental Site Assessment (ESA) is often required to determine whether contamination actually exists.

DCG Environmental performs fast, accurate Phase II ESA testing across Texas to help buyers, developers, and property owners understand their risk and take informed action. We specialize in cost-effective, regulatory-compliant site investigations that get you answers without unnecessary delays.

What Is a Phase II ESA?

A Phase II ESA is a more in-depth investigation designed to confirm or rule out the presence of environmental contamination at a property.

phase II ESA includes:

Unlike a Phase I ESA (which is historical and observational), a Phase II ESA includes physical sampling and lab testing to assess the presence of hazardous substances.

When Is a Phase II ESA Needed?

You may need a Phase I ESA if:

A Phase I ESA identifies a Recognized Environmental   Condition (REC)
A lender, buyer, or regulator requires confirmation of   environmental status
You plan to redevelop a site with historical chemical,   fuel, or manufacturing use
You need documentation to limit liability or support   cleanup decisions

Properties with historical use tied to chemicals, fuel, manufacturing, agriculture, or industrial processes should always be evaluated.

Typical Triggers for a Phase II ESA Include:

DCG’s Phase I ESA reports include:
