This Maptitude map shows the locations and concentrations of EPA National Priorities List, also known as Superfund, sites. These sites require a long-term response to clean up hazardous contaminants. Each triangle shows the location of a NPL site, and the states are shown with a color theme showing the per capita concentration of sites.
