There are approximately 587,000 underground storage tanks (USTs) nationwide that store petroleum or hazardous substances. The greatest potential threat from a leaking UST is contamination of groundwater, the source of drinking water for nearly half of all Americans. EPA, states, and tribes work together to protect the environment and human health from potential UST releases. You can learn more about USTs on our Basic Information page.
