ATSDR Hazardous Waste Site Polygon Data, Version 2 contains 2,080 polygon boundaries for selected hazardous waste sites. The dataset was compiled by the Geospatial Research, Analysis, and Services Program (GRASP) within the CDC's ATSDR on May 26, 2010. Most polygons represent sites considered for cleanup under the Superfund program.
Use Cases
- Analyze spatial relationships between site polygons and population demographics for exposure risk assessment.
- Calculate the total area covered by hazardous waste site polygons to estimate regional contamination footprint.
- Overlay site polygons with land use or waterbody data to identify potential environmental pathways.
- Identify clusters of site polygons to prioritize regions for further health investigations.
Strengths
- Contains 2,080 distinct site polygons.
- Focuses on sites formally considered for federal Superfund cleanup.
Limitations
- Data is static with a compilation date of May 26, 2010; does not reflect newer sites or boundary changes.
- Limited to sites where a health assessment or consultation was requested, not a complete national inventory.
