Cleanup Sites
Environmental Effects Indicator
Counts contaminated sites awaiting cleanup near communities—sources of hazardous chemicals that can persist for years or decades.
What are cleanup sites?
Cleanup sites are places contaminated with harmful chemicals and need to be cleaned up by the property owners or government. People living near these sites are more likely to be exposed to chemicals from the sites than people living further away. Some studies have shown that neighborhoods with cleanup sites are generally poorer and have more people of color than other neighborhoods.
Why is it included in CalEnviroScreen?
- Chemicals in the buildings, soil, or water at cleanup sites can move into nearby communities through the air or by movement of water.
- The land may take many years or decades to clean up, reducing possible benefits to the community.
- Scientists have found toxic metals in house dust and pesticides in the blood of people who live near contaminated sites.
How is it measured?
- The Department of Toxic Substances Control (DTSC) tracks cleanups of contaminated sites in California through the EnviroStor database. These cleanup site data were downloaded in March 2026.
- The indicator combines the sites in or near each census tract. This combination accounts for the type of site it is and how close it is to where people may live.
