Floods and Fires Threaten America’s Biggest Toxic Sites

The U.S. Environmental Protection Agency’s internal Inspector General has discovered that almost a hundred of the country’s most dangerous Superfund sites are located in regions prone to flooding and wildfires—posing a direct threat to the health of millions nearby.

Key Findings

• Scope of Study: 157 federal Superfund sites selected for cleanup due to severe environmental danger.
• Population at Risk:
• ~3 million Americans live within a mile of a site.
• ~13 million more live within three miles.
• Climate Threats:
• Flooding can transport hazardous chemicals into rivers and groundwater.
• Wildfires can carry pollutants across large distances, especially under dry heat and wind.

Implications

• Economic Vulnerability: Communities already facing economic challenges may be most affected.
• Emergency Preparedness Gaps:
• Many sites lack clear evacuation instructions for nearby residents.
• Plans to handle spills during disasters are often insufficient.

EPA’s Response

The agency plans to use the report to:

• Strengthen barriers around high‑risk sites.
• Enhance monitoring systems.
• Incorporate climate risk assessments into cleanup prioritization.

Call to Action

The Inspector General’s warning highlights that climate‑related disasters could transform a cleanup site into a public health crisis. Prompt action is essential to protect vulnerable populations from floods and fires before they become an even greater threat.
