The Western Region Hazardous Substance Research Center developed treatment methods and provided technical assistance for cleanup of hazardous substances. It operated from 1989 through 2007 and was a partnership between Oregon State University and Stanford University. The Center received its base financial support from the U.S. Environmental Protection Agency.

Although the Center has ceased operations, this Web site has been retained as an archive of Center publications and project information. For questions about the WRHSRC, please contact Dr. Lewis Semprini, Oregon State University professor of environmental engineering, who served as the WRHSRC director from 2000-2007.

The objectives of the WRHSRC were to:

• Develop new ways to clean up groundwater contaminated with volatile organic compounds (VOC's) such as trichloroethylene (TCE).

• Promote the use of new technologies through demonstration projects, workshops, and information exchanges with industry and regulatory communities.

• Provide assistance to communities affected by hazardous substances through the Technical Outreach for Communities (TOSC) and the Technical Assistance to Brownfield Communities (TAB) programs.
