Home with an Underground Heating Oil Tank (UST)


Vent & Fill Pipes are the visible signs that there is a Heating Oil Tank at this home.

Home with an Underground Heating Oil Tank (UST)


This cut-a-way view shows a typical Heating Oil Tank installation. Tanks are usually placed approximately 2 feet below the ground.

Oil stains near the Fill Pipe DOES NOT mean a Tank has leaked.

As the Tank ages, it will eventually leak. leaked.

DOWN GRADIATIANT leaked.

Soil Permeability, Porosity, Ground Water (if present), and Topography will determine the speed and direction the “Oil Plume” will travel.

Home with an Underground Heating Oil Tank (UST)


To determine if a Tank has leaked, Soil Samples are taken from opposite ends of and below the Tank .

The remedy for a leaking Tank starts with pumping out the Tank. Next, the top is exposed and the interior cleaned in preparation for excavation.

The Tank is then carefully excavated from the ground. Tank. Next, the top is exposed and the interior cleaned in preparation for excavation.

Once the Tank is removed, you have Tank. Next, the top is exposed and the interior cleaned in preparation for excavation.

Two Options to deal with the remaining Contaminated Soil.

A.) Excavation of the Contaminated Soil.

B.) Bio-Remediation Treatment of the Soil.

Home with an Underground Heating Oil Tank (UST)


Cleanup Option A: Excavation of Contaminated Soil Tank. Next, the top is exposed and the interior cleaned in preparation for excavation.

In this process: All accessible Contaminated Soil is excavated and transported to an approved disposal facility.

5 to 10 feet

10 to 20 feet

Up to 15 feet or more in depth

Excavations vary in size depending severity of the leak.


Cleanup Option A: Excavation of Contaminated Soil Tank. Next, the top is exposed and the interior cleaned in preparation for excavation.

This method is recommended if a property is going to sell within 5 years. This option permits rapid site closure if the impacted Soil can be removed and clean samples obtained.

5 to 10 feet

10 to 20 feet

Up to 15 feet or more in depth


Cleanup Option A: Excavation of Contaminated Soil Tank. Next, the top is exposed and the interior cleaned in preparation for excavation.

The disadvantage to this method is that it can be damaging to surrounding landscape, driveways, decks, etc. Below the surface, sewer lines, water lines and utilities could be impacted.

5 to 10 feet

10 to 20 feet

Up to 15 feet or more in depth


Cleanup Option B: Bio-Remediation Tank. Next, the top is exposed and the interior cleaned in preparation for excavation.

Bio-Remediation is less intrusive than Excavation, but should be considered when a house will not be sold within the next 5 years.


Cleanup Option B: Bio-Remediation Tank. Next, the top is exposed and the interior cleaned in preparation for excavation.

This is an acceptable method by Regulatory Agencies. It can be done as an alternative to Excavation or as enhancement when Soil is not accessible for Excavation.


Cleanup Option B: Bio-Remediation Tank. Next, the top is exposed and the interior cleaned in preparation for excavation.

First: 2 inch Ports are installed and cut flush with the ground level .

A gravel bed helps spread the Remediating Bacteria.


Cleanup Option B: Bio-Remediation Tank. Next, the top is exposed and the interior cleaned in preparation for excavation.

Next: Bio-Remediation & Oxygen is introduced into these ports over a period of time.


Cleanup Option B: Bio-Remediation Tank. Next, the top is exposed and the interior cleaned in preparation for excavation.

After several applications, the Soil will become more saturated with Oxygen and Remediating Bacteria.


Cleanup Option B: Bio-Remediation Tank. Next, the top is exposed and the interior cleaned in preparation for excavation.

Amount of Treatments and the length of time for Remediation to occur, depends on severity of contamination at each site.


Cleanup Option B: Bio-Remediation Tank. Next, the top is exposed and the interior cleaned in preparation for excavation.

Over a period of time, the Contamination will degrade and dissipate.


Cleanup Option B: Bio-Remediation Tank. Next, the top is exposed and the interior cleaned in preparation for excavation.

After the initial phase of Applications, the Ports will be cut and capped flush to the ground.


Cleanup Option B: Bio-Remediation Tank. Next, the top is exposed and the interior cleaned in preparation for excavation.

These Ports can be accessed in the future for additional Bio-Applications if necessary.


Cleanup Option B: Bio-Remediation Tank. Next, the top is exposed and the interior cleaned in preparation for excavation.

Cleanup Option A: Excavation of Contaminated Soil

PROS:Remediation takes less time.

CONS:More intrusive to the Property and Utilities.

Generally more expensive.

PROS:Less intrusive to Property.Generally Less expensive.

CONS:May take a few years to complete.
