Underground storage tanks may be mentioned in municipal or fire department records. We use our contacts at the municipalities and fire departments to see if they have useful information. This record check is included as part of our underground oil tank scan. Sometime archived Multiple Listings reports mention oil tanks and we attempt to check these as well. Properties where a history of UST removal and certification is not available from the homeowner or municipality should be tested. A Ground Penetrating Radar (GPR) scan helps determine the possibility of buried tanks and can indicate areas where tanks may have been removed.
