EPA Superfund Site Feature Locations as Geospatial Points

U.S. EPA Superfund features are captured as point data for geospatial analysis. Regional teams manage the features, and the national dataset is refreshed weekly by the SEGS system. The dataset is reserved for important site features best represented as points.

Use Cases

• Mapping contaminant point sources based on described Superfund site features.
• Analyzing spatial distribution of remediation sites based on the geospatial point data.
• Integrating point features into environmental risk models based on the described EPA management structure.
• Monitoring regional data updates for site management based on the weekly refresh cadence.

Strengths

• Data is refreshed on a weekly basis by the SEGS system.
• Features are managed by regional teams of geospatial professionals and remedial program managers.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
