There has been undeniable success in the cleanup of the nation’s hazardous waste and brownfields sites. However, annual funding for Superfund site cleanup is estimated to be as much as $500 million short of what is needed. 1,280 sites remain on the National Priorities List, with an unknown number of potential sites yet to be identified.
The National Priority List (NPL), maintained by the EPA, lists the known sites that release or threaten release of hazardous substances, pollutants, or contaminants throughout the United States and its territories.
Since 1980, the EPA has investigated more than 47,000 sites suspected of releasing hazardous substances into the environment. Just over 1,600 sites have been placed on the NPL, and cleanup has been implemented at more than two-thirds of those sites.
There are likely more potential Superfund sites in the United States, but how many is unknown. Polyurea protective coatings are a cost effective way to create secondary containment liners to protect our fragile environment from accidental spills of hazardous chemicals. With service life measured in decades, SPI’s polyureas have excellent potential to help protect our precious natural resources and protect our citizens.
