ADEQ's Leaking Underground Storage Tank program investigates and coordinates efforts to clean up leaking USTs once a release has occurred. These efforts may include overseeing cleanups performed by the leaking UST owner, operator or by a volunteer who is willing to assume responsibility. ADEQ also may perform corrective actions itself using consultants who are on state contract.
