28,233 facilities · 24,836 LUST releases
Illinois faces significant environmental challenges related to underground storage tanks (USTs). The state has 28,233 registered UST facilities, encompassing 17,906 active tanks and 66,415 closed tanks. A substantial concern arises from the 25,336 documented leaking underground storage tank (LUST) release sites, with 5,925 currently classified as "Open" and still requiring cleanup. This data is sourced from the EPA UST Finder program.
The widespread presence of USTs underscores the critical importance of continuous monitoring, thorough environmental due diligence, and robust groundwater protection efforts. Cities such as Chicago, with 2902 facilities and 4057 releases, Rockford (647 facilities, 386 releases), Springfield (394 facilities, 367 releases), Peoria (365 facilities, 221 releases), and Decatur (278 facilities, 241 releases) demonstrate the localized impact of these facilities and associated releases. Proactive management and diligent oversight are essential to mitigate the risks of environmental contamination from UST leaks across Illinois.
