Delaware UST Directory
2,928 facilities · 7 LUST releases
Delaware manages a substantial infrastructure of underground storage tanks (USTs), with 2,928 registered UST facilities across the state. These facilities include 1,180 active USTs, in addition to 8,204 closed tanks. The historical operation of these tanks has resulted in environmental impacts, as evidenced by 4,979 documented leaking underground storage tank (LUST) release sites. Of these, 111 releases are currently classified as "Open," signifying ongoing cleanup and remediation efforts. Data concerning USTs in Delaware is sourced from the EPA UST Finder program.
The presence of USTs necessitates vigilant monitoring and maintenance to prevent environmental contamination. Leaks from these tanks can introduce petroleum products and other hazardous substances into the surrounding soil and, critically, into groundwater resources. Therefore, comprehensive environmental due diligence is paramount for property owners and regulators alike. Proactive measures and timely remediation are essential to safeguard public health and ensure the long-term protection of Delaware's vital groundwater supplies from potential UST-related pollution.
