Overview

Until the mid-1980s most underground storage tanks (USTs) were made of bare steel, which is likely to corrode over time and allow UST contents to leak into the environment. The greatest potential hazard from a leaking UST is that its contents (petroleum or other hazardous substances) can seep into the soil and contaminate groundwater, the source of drinking water for nearly half of all Americans.

An underground storage tank system (UST) is a tank and any underground piping connected to the tank that has at least 10 percent of its combined volume underground. . . Nearly all USTs regulated by the underground storage tank requirements contain petroleum.
