Home Heating Oil in Groundwater FAQ

Did your oil tank leak?

We check the water and clean it up.

What is a groundwater investigation?

It’s when we test the water underground (below your yard) to check if it was impacted by a heating oil leak.

Why would my groundwater need to be tested?

If your oil tank leaked, the oil might have reached the groundwater. Testing shows if it's safe.

How do you test the groundwater?

We drill down and put a small temporary well in your yard, collect water samples, and send them to a lab to check for oil-related chemicals.

Is groundwater testing required by NJDEP?

Yes—if we find signs that oil may have reached the water. NJDEP wants to make sure your property and nearby areas are protected.

What happens if contamination is found in the water?

We’ll create a cleanup plan, approved by NJDEP. This may involve ongoing monitoring, removing contamination, or other treatments.

Will I need more than one test?

Sometimes, yes. NJDEP often requires more than one round of testing to track the problem and make sure cleanup is working.

Can I sell my home if groundwater is impacted?

Not until the issue is cleaned up or properly managed. We help you through the process so you can close your deal with confidence.

How long does groundwater cleanup take?

It depends on how bad the problem is. Some cases take a few months, others may need long-term monitoring. We’ll explain everything clearly.

Will the cleanup damage my yard?

We work carefully to limit disruption. Most of the work is in small areas, and we clean up after we’re done.
