Most homes built before 1975 used an underground oil tank.90% of these tanks are leaking.
These thin steel tanks have been corroding underground for 50 to 80 years, far beyond their life expectancy. Thousands of these tanks are still in the ground contaminating soil and groundwater. Because groundwater is always moving, contamination from leaking oil tanks will eventually contaminate a neighbor’s property, irrigation well(s), underground utilities, and/or surface drainage ways.
