Underground heating oil tanks can pose many potential problems to both home buyers and sellers. They 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.
