Why is petroleum underground storage tanks (USTs) a concern?
Petroleum products have been typically stored in steel USTs; which, will eventually fail due to rust and corrosion. When corrosion causes holes in the UST or the seams of the tank fails, petroleum leaks into the subsurface soil and/or groundwater. Buried USTs can cause a variety of environmental, safety, legal and economic concerns for property owners or property buyers. The biggest economic issues consist of the cost and risks associated with tank removal, investigation, testing and site cleanup (remediation).
