The National Institute of Environmental Health Sciences (NIEHS) Superfund Research Program (SRP) produces a monthly Research Brief Podcast that highlights the research of SRP grantees. The SRP is a network of university grants that seek solutions to the complex health and environmental issues associated with the nation's hazardous waste sites. The research conducted by the SRP is a coordinated effort with the Environmental Protection Agency, which is the federal entity charged with cleaning up the worst hazardous waste sites in the country.
