What is "CERCLIS"?

CERCLIS (Comprehensive Environmental Response, Compensation and Liability Information System) and SEMS (Superfund Enterprise Management System) are databases maintained by the US EPA as part of the Superfund program. The EPA retired CERCLIS in November 2013 and has been transitioning to SEMS, which contains the same content as CERCLIS. SEMS contains information such as the current status of cleanup efforts, cleanup milestones reached, and amounts of liquid and solid media treated at sites on the National Priorities List (NPL) or under consideration for the NPL.
