Abstract: Process and apparatus for detecting leaks in, cathodically protecting, determining the effectiveness of such cathodic protection, and/or remediating fluid leaked from an aboveground storage tank. At least one substantially horizontal bore is formed beneath an aboveground storage tank and a slotted pipe or casing is positioned within the bore. The pipe or casing can be simultaneously advanced within the substantially horizontal bore while the bore is being formed. Slotted tubing and at least one anode are positioned within the slotted casing. The bore is filled with coke breeze and current is supplied to the anode(s) to cathodically protect substantially the entire tank bottom. The anode and slotted tubing can be removed to provide a passageway for remediation of fluid leakage from the storage tank.
