List of Contaminated or Potentially Contaminated Sites - SASU Case Management System

Published by data.ct.gov | State of Connecticut | Metadata Last Checked: January 10, 2026 | Last Modified: 2026-01-10
This is a list of sites from the “SASU (Site Assessment and Support Unit) Case Management” System, which is also known as the LUST Database. Sites on this list include, but are not limited to: sites with known releases from regulated Underground Storage Tank (UST) systems, sites with releases from non-regulated UST system sources, releases from non-UST related sources, sites with potential releases for which impacts or sources of release were not confirmed at time of entry into the system. The “SASU Case Management” system was initially developed in the late 1980’s/early 1990’s to track sites that the Site Assessment and Support Unit (SASU) worked on. At the time SASU contained the LUST Program. Overtime the “SASU Case Management” System evolved to primarily track releases from regulated Leaking Underground Storage Tanks (LUST) and is currently maintained by the DEEP’s Corrective Action Unit (CAU). This dataset does not replace a full review of other environmental datasets available through CT Open Data, HazConnect (https://connecticut.hazconnect.com/listincidentpublic.aspx), files publicly available either using the DEEP on-line Public Portal (https://filings.deep.ct.gov/DEEPDocumentSearchPortal/) and/or at the DEEP Record Center File Room (https://portal.ct.gov/DEEP/About/Environmental-Quality-Records-Records-Center-File-Room). We know there may be errors in the data although we strive to minimize them. Examples of errors may include: misspelled or incomplete addresses and/or missing data. A separate dataset ( https://data.ct.gov/Environment-and-Natural-Resources/List-of-Contaminated-or-Potentially-Contaminated-S/u76p-weqj/data ) is also published for: List of Contaminated or Potentially Contaminated Sites - Remediation Division. The two database systems are maintained by different Divisions within the agency. There may be sites in both databases due to an overlap in responsibilities of the two Divisions.
