New Jersey, California, and Pennsylvania are the states that have the greatest number of Superfund sites in the United States.
The Superfund program, administered by the U.S. Environmental Protection Agency (EPA), was established under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980. Its primary goal is to clean up hazardous waste sites that pose risks to human health and the environment. These sites often include former industrial facilities, landfills, and mining operations where hazardous substances have been released.
Historically, states with significant industrial activity and high population densities tend to have a larger legacy of contaminated sites. Based on available information, New Jersey, California, and Pennsylvania consistently rank at the top, collectively possessing the greatest concentration of Superfund sites nationwide. This indicates a substantial history of industrial development and the resulting environmental impact in these regions, necessitating extensive remediation efforts.
States Identified with the Most Superfund Sites
| State | Superfund Site Status |
|---|---|
| New Jersey | Identified as having the greatest number of sites |
| California | Identified as having the greatest number of sites |
| Pennsylvania | Identified as having the greatest number of sites |
The ongoing efforts by the EPA and state agencies aim to address these sites, ensuring public safety and environmental restoration. The presence of numerous Superfund sites highlights the long-term commitment required to manage and mitigate the impacts of past industrial practices.
