ABSTRACT:
Methods and apparatuses for detecting leakage of hydrocarbons from and preventing corrosion of underground storage tanks. Soil samples near an underground storage tank are taken and analyzed in the field, preferably using hexane as a solvent to detect the presence of hydrocarbons such as heating and waste oil. The soil-to-tank potential of the tank and the presence of water within the tank are measured and, if warranted, cathodic protection provided to the tank to prevent corrosion or further corrosion.
