Superfund Site Management and Remediation Data

U.S. Environmental Protection Agency data provides site-specific information for Superfund sites governed under CERCLA and SARA. The collection includes site descriptions, locations, schedules, enforcement actions, contaminants, remedies, and lab results from systems like SEMS.

Use Cases

• Analyze contaminant types and selected remedies across Superfund sites to assess common cleanup strategies.
• Map site locations and statuses to identify geographic clusters of environmental remediation activity.
• Examine enforcement and settlement data to study patterns in regulatory actions and compliance timelines.
• Use sampling data and lab results (CLPSS, EDDs) to model contaminant dispersion or treatment effectiveness.

Strengths

• Data originates from the authoritative U.S. Environmental Protection Agency, the governing body for Superfund.
• Includes a wide scope of information such as site management records (RODs, remediation plans), technical assistance, and redevelopment case studies.
• Updated recently, with a last recorded update in September 2025.

Limitations

• Specific data structure is undefined; columns, rows, and file formats are unknown, complicating direct analysis.
• Potential for data fragmentation across multiple agency systems (EAS, COMPASS) and individual datasets within the asset.
