[CPEO-MEF] Webinar: Managing the Nation's Contaminated Groundwater Sites

Â
Â
Â
You are invited to join a public webinar on Wednesday, December 12 exploringÂAlternatives for Managing the Nation's Complex Contaminated Groundwater SitesÂ, a new report from the National Research Council of
the National Academies.
Â
Â
Across the United States, thousands of hazardous waste sites are contaminated with chemicals that prevent the underlying groundwater from meeting drinking water standards. While many sites have been closed over the past 30 years through cleanup programs run by the U.S. Department of Defense, the U.S. EPA, and other state and federal agencies, the remaining caseload is much more difficult to address because the nature of the contamination and subsurface conditions make it difficult to achieve drinking water standards in the affected groundwater. This report estimates that at least 126,000 sites across the U.S. still have contaminated groundwater, and their closure is expected to cost at least $110 billion to $127 billion. About 10 percent of these sites are considered "complex," meaning restoration is unlikely to be achieved in the next 50 to 100 years due to technological limitations. The central theme of this report is how the nation will deal with the complex hazardous waste sites where contamination remains in place at levels above drinking water standards.
