Prior to the mid 90's local authorities did not require permits or inspections when a residential oil tank was removed or abandoned in place, therefore, most times there is a lack of available documentation at the local town hall or Fire Marshalls office to determine if a property may have had an underground oil tank. Often times, due to many years and many owners, the current owner of the home may not be aware of the existence of an underground tank, especially in older homes which often had oil tanks for heating that were abandoned when converting to natural gas. Oil Tank Locating has become a frequent service due to real estate disclosure rules and the increased knowledge of the environmental impacts, hazards and costs associated with removal of old, or unidentified underground oil tanks and the clean-up of contaminated soil, if found to be leaking. Absolute Tank Testing can perform a tank search/scan to determine the existence of an underground oil tank that may otherwise go undetected.
There are several signs that a property may have an undisclosed/unknown underground oil tank:
■ Homes built prior to 1980 and are now heated with natural gas.
■ Extra copper lines protruding through a foundation wall from the outside.
■ Holes or concrete patching in the foundation wall or floor.
■ Pipes visible from the ground, along a driveway or road side.
