Chemical Cleanup
Furnaces that are presently fuelled, or were fuelled in the past, by oil required an oil storage tank. These tanks were generally located above ground, in basement areas, or buried outside near foundation walls. If tanks are present there is potential for from the tanks themselves or from associated piping. Buried tanks were used largely in industrial or commercial buildings. However, many larger residential buildings also used underground storage tanks for oil storage. Any buried fuel oil tanks not in use are required to be removed by law. These ranks may pose potentially large and costly environmental problems and represent a large potential liability for owners and architects.
