Description:
Objective:The Western Region Hazardous Substance Research Center (WRHSRC) was a cooperative activity between Oregon State University and Stanford University that was renewed in October 2001. The Center was a continuation of the original Center established in 1989 to address critical hazardous substance problems in EPA Regions 9 and 10. The regions include the states of Alaska, Arizona, California, Hawaii, Idaho, Nevada, Oregon, and Washington, and Guam. The research focus of the Center was to develop in situ processes for VOC remediation in groundwater and Soil.
Goals:
The goals of the Center were to:
- Develop innovative technologies for the in situ treatment of volatile organic chemicals (VOCs) in groundwater, especially chlorinated solvents.
- Increase the number, speed, and efficiency of available treatment options for both high concentration source zones and diffuse contamination plumes.
- Disseminate the results of research to the industrial and regulatory communities, to foster exchange of information with these communities, and to promote a better understanding of the scientific capability to detect, assess, and mitigate risks associated with hazardous substance usage and disposal.
Groundwater cleanup and site remediation, with a strong emphasis on treatments that used microbes or chemical catalysts to transform VOCs into harmless substances, represented the major focus of Center’s research activities. Research projects included biological (biotic) and physical and chemical (abiotic) treatment processes, as well as in situ characterization methods for monitoring the progress of both intrinsic and enhanced remediation. In combination with basic laboratory and field studies, physical and mathematical models were developed to study these processes and to provide a bridge between theory and practice. The technology transfer program involved the process of taking new technologies from the laboratory to the field. Center researchers worked with other federal agencies, such as the Department of Defense (DoD) and private industry, in conducting field evaluations of new technologies. Technical Outreach Services for Communities (TOSC) was a technical assistance program designed to aid communities confronted with environmental contamination by hazardous waste sites. TOSC provided interested community groups with technical information and assistance that enabled early and meaningful public participation in decisions that affect health and welfare. The Center’s Technical Assistance to Brownfields Communities (TAB) program provided assistance to communities attempting to address cleanup and redevelopment of properties whose reuse has been prevented by real or perceived contamination. TAB attempted to improve involvement of all affected parties in cleanup and redevelopment process through education and training.
Lewis Semprini was the director of the Center and of the research program. Kenneth J. Williamson served as associate director in charge of training, technology transfer and community outreach. Martin Reinhard, the assistant director, was in charge of the Center's quality control program. Garrett Jones was the Center's administrative assistant. Fifteen OSU and Stanford faculty members were involved in the Center. They collectively represented an integrated research group of many different disciplines, including biochemistry, chemistry, environmental engineering, environmental chemistry, geosciences, hydrogeology, molecular biology, microbiology, public health, and sociology.
The Center had two major advisory groups to guide its activities. The Science Advisory Committee (SAC) had oversight for all Center research activities and technology transfer activities, and the Outreach Advisory Committee (OAC) oversaw the Center's TOSC and TAB programs. The members of the SAC and OAC represented federal and state governments, industry, consulting firms, and universities. Experts with a broad range of expertise were included in the SAC and the OAC.
The Center received a total of $3,763,200 of funds from the EPA. The EPA required matching funds at a level of 20%. Oregon State University allocated $405,000 in funds to help meet this required match.
Summary/Accomplishments (Outputs/Outcomes):The final report for the Western Region Hazardous Substance Research Center provides an overview of the accomplishments of the Center for the period of October 2001 to August 2007. The Center funded twelve research projects and an Outreach Center for the TOSC and TAB programs. The report provides final summary reports for all the Center’s projects. Publications that resulted from the Center’s research projects are also listed as well as publications that resulted from the field demonstrations. Provided below are the research projects and the PIs and the Co-PIs of the projects.

Doctoral and Master’s Degrees
One of the most import functions of the Center was the education of the next generation of researchers, educators, and practitioners in the area of subsurface remediation. A total of 19 Ph.D. students, five M.S. students, and one post-doctoral student were supported through the Center’s funding research projects.
Technology Transfer
Center researchers were involved with technology transfer through involvement in field demonstration projects, supporting the development of Research Briefs, and the publication of the results of their research, as previously described. Six field demonstration projects that resulted from basis or applied research funded by the Center. These field demonstration projects were funded by other governmental agencies such as Environmental Security Technology Certification Program (ESTCP) and the Strategic Environmental Research and Development Program (SERDP) of the Department of Defense. Several field demonstrations were also supported by Chevron-Texaco Corporation and Textron Corporation. Two of the projects, one funded by ESTCP and another by SERDP, were associated with demonstrations and the development of protocols to assess aerobic cometabolism. Another ESTCP project was centered on using radon-222 as in situ tracer for monitoring the remediation of NAPL contamination. A third ESTCP project evaluated Pd-catalysts for the in situ treatment of TCE using horizontal wells. Chevron-Texaco and Textron Corporation supported field push-pull test demonstrations using trichlorofluoroethene as a reactive tracer for evaluating TCE remediation.
To aid in technology transfer, a Website was developed and maintained during the life of the Center. The web site http://wrhsrc.oregonstate.edu/ 
provided an overview of the WRHSRC and links to publications and project information. The website included a description of the HSRC program and WRHSRC goals and management; links and contact information for center research and outreach staff; descriptions of research focus areas and projects; a searchable database of WRHSRC publications and previous projects (http://wrhsrc.oregonstate.edu/publications/index.htm ); descriptions of center outreach programs and links to the separate Websites for the Western Region TOSC/TAB programs; a news and events page with regular postings; and an opportunity to sign up to receive electronic newsletters from the WRHSRC and the TOSC/TAB programs. The Web site received an average of 1400 visits per month. Common search terms that lead visitors to the site include reductive dechlorination, cometabolism, anaerobic processes, palladium catalysts, and individual researchers’ names. The Research Briefs were among the most commonly viewed pages.
Another product of the technology transfer program was Research Briefs, which provided short summaries of Center projects and also emphasized research applications and demonstration projects. The Research Briefs were advertised through the Center electronic newsletter and announced on other electronic mailing lists read by the groundwater remediation community such as Tech Direct, USEPA Region 10 Science Forum (intranet site), and USEPA Region 9 Hazardous Substance Technical Liaison Newsletter. Over the life of the Center, ten Research Briefs were written. These Research Briefs at located at the following Web address: (http://wrhsrc.oregonstate.edu/briefs/index.htm ).
TOSC and TAB
The Technical Outreach Services for Communities (TOSC) Program was a technical assistance project designed to aid communities confronted with environmental contamination by hazardous waste sites. The TOSC and TAB were funded directly through the Center, or through collateral grants. TOSC provided interested community groups with technical information and assistance to encourage early and meaningful public participation in decisions that affect their health and welfare. The TOSC program provided a viable alternative source of assistance for communities that did not qualify for a Technical Assistance Grant (TAG) from the US Environmental Protection Agency. Centered at Oregon State University, the TOSC team involved university faculty and students, as well as contracted environmental professionals with specialization in environmental engineering, risk communication, public health, information transfer, environmental justice, and community relations. Where appropriate, WR TOSC partnered with staff of the Technical Outreach Services for Native American Communities (TOSNAC) to provide assistance to tribal communities. From 2001 to 2007 TOSC provided technical assistance to 36 communities in Region 9 and 10. The TAB provided assistance to 17 Brownfields projects. The program also helped organize two Oregon Rural Brownfields Conferences (2001, 2002) and two Oregon Brownfields Conferences (2005, 2007).
