Tank Sweeps or Tank Survey
An oil tank sweep is one of the best ways to locate buried oil tanks.
Tank sweeps are also part of any buyer's due diligence process. Undisclosed abandoned underground oil tanks (USTs) are a financial liability that can loom over a site. Buried oil tanks that have not been properly abandoned (Meaning tested and documented that the tank has not leaked) are a cause for concern. Not properly abandoned means, still containing oil or a tank that has or is leaking but is undisclosed. These tanks are often well past their useful service life and have often leaked. Buying a contaminated property means you are responsible for the cleanup costs even though you may have no prior knowledge of the contamination. Cleanups (remediations) are costly – ranging from $5,000 to $100,000.00. These tank leaks are often excluded from insurance policies, so you the homeowners will not pay for the loss and you the homeowner wind up paying for someone else problem.

Did You Know?
- Oil heat was popular from the 1940s into the 1990s.
- A typical life span of an oil tank is similar to a roof. Meaning if a roof was replaced so should a tank.
- Many oil tanks were abandoned with oil in them when homes were converted to from oil to gas. So abandoned tanks were just that abandoned.
- Some homeowners have removed tank piping to disguise a tank location to avoid having to deal with the tank themselves. Tank sweeps can find these tanks.
- Tank Sweeps with GPR (Ground Penetrating Radar) are the most though way to scan for a tank. Tank Sweeps using only metal detectors can give false information as the metal detector is subject to interference from metal siding, mesh in stucco, metal in concrete, buried metal pipes, and ferrous present in the ground.
- Home inspections do not include Oil Tank Sweeps as part of their inspection.
