Comprehensive Environmental Response and Cleanup Information System
The Comprehensive Environmental Response and Cleanup Information System (CERLIS) contains information on Superfund sites, such as hazardous waste sites, potentially hazardous waste sites and remedial activities across the nation, including sites that are on the National Priorities List (NPL) or being considered for the NPL. The CERLIS Public Access Database contains a selected set of "non-enforcement confidential" information and is updated by the regions every 90 days. The data describe what has happened at Superfund sites prior to the current quarter. Site information for NPL sites is displayed in a standardized site progress profile format. The profile includes information such as the current status of cleanup efforts, what cleanup milestones have been reached and how much liquid and solid-based media have been treated. All information is presented in easy to understand, non-technical language. Only NPL sites are displayed in the site progress profile format; non-NPL and archived sites are displayed in a less graphical format.
