Research Centers
South and Southwest HSRC

Louisiana State University - Baton Rouge

The objective of the proposed Hazardous Substance Research Center/South and Southwest (HSRC/S&SW) is to provide basic and applied research, technology transfer and community outreach that address hazardous substance problems, especially the engineering management of contaminated sediments and other problems of special interest to communities within EPA Regions 4 and 6. Due to past and present toxic releases, these regions face serious hazardous substance problems and yet contain a significant fraction of the wetlands and inland waters found in the United States. The mission of the Center is to be a primary provider of the tools and process knowledge required to resolve problems posing the greatest risks to people and the environment.
