Underground heating oil tanks have been the source of many environmental problems such as contamination of surrounding soil and ground water.

Leaks are caused by the rust inside underground tanks, or by an electrical condition sparked by electric utility lines.

Buyers should have the tank inspected to make sure that it is structurally sound. Buyers who do not want an underground fuel tank can arrange for an above ground tank to be installed in the basement, an underground tank to be shut off. Cleanups of any leaks will also have to be taken care of.

For buyers, the existence of the underground heating oil tank should be written into the sales contract. For sellers, your attorney should make sure that the description and condition of the underground heating oil is accurate and up-to-date.
