Phase II Environmental Site Assessment (ESA) FAQ

Need soil, water, or vapor testing?

Here’s what to know about a Phase II.

What is a Phase II ESA?

A Phase II ESA tests the soil, groundwater, or air to check for contamination. It tells you if there’s a real problem under the ground.

When do I need a Phase II ESA?

You need one when a Phase I ESA finds signs of possible contamination—like old tanks, spills, or past industrial use (called a "Recognized Environmental Condition" or REC).

What does a Phase II ESA include?

It includes site testing, lab analysis, a review of results, and a clear report showing if there are environmental risks.

Does a Phase II mean the site is unsafe?

Not always. It just means we need to test and find out. Sometimes results come back clean, and no additional action is needed.

How long does a Phase II take?

Most Phase IIs take 1 to 3 weeks, depending on how much testing is needed and how fast the lab can process the samples.

What kind of samples are taken?

It depends on what the Phase I found.

We usually take soil, groundwater, and sometimes vapor samples.

What happens if contamination is found?

We’ll explain what it means and what to do next. The site may need cleanup or a plan to manage the issue, depending on the results.

Do I need a Phase II to get financing?

Sometimes. If the Phase I raised concerns, banks may require Phase II testing before they approve a loan or close the deal.

Can I do a Phase II without a Phase I?

It’s not recommended. A Phase I helps guide where to test, so your Phase II is targeted and cost-effective.
