About the WRHSRC
The Western Region Hazardous
Substance Research Center (WRHSRC) is one of five regional
hazardous substance research centers in the United States.
The Centers are funded by grants from the US EPA Office
of Research and Development and Office of Solid Waste and
Emergency Response. Through periodic email updates, we hope
enhance communication with our colleagues in the Western
Region. For more information visit: http://wrhsrc.orst.edu

Quarterly Feature Story
In August, Center researchers, graduate students,
outreach specialists, and advisory committee members met for the
first annual meeting of the new WRHSRC. The meeting was an excellent
introduction to the Center's goals -- to improve technologies
for cleanup of chlorinated solvents in groundwater and to provide
assistance to western communities affected by hazardous substance
Researchers from Oregon State University (OSU) and
Stanford gave presentations highlighting the Center's seven main
research projects and two community outreach programs.
Peter Kitanidis (Stanford) described his group's research
on ways to increase the rate of delivery and mixing of additives
required for in situ remediation. He highlighted a demonstration
project they are working on for remediation of Uranium contamination
at Oakridge National Labs.
Lewis Semprini (OSU) spoke about his project with Mark Dolan
to test the cleanup effectiveness of a combined microbial
culture for treating high concentrations of PCE and TCE.

John Westall, Naoko Munakata participating in the student
Mark Dolan reviewed his groups research to maximize rates
of CAH remediation through cometabolism with Butane-grown
bacteria. He also described field tests of the technology.
Naoko Munakata (doctoral candidate, Stanford) talked about
her research with Martin Reinhard and John Westall to improve
the effectiveness of palladium catalysts to treat chlorinated
solvents. Their focus is on better understanding the fouling
process that slows catalyst activity and to develop ways to
retain or regenerate their effectiveness in situ.
Jeff Cunningham (post-doc, Stanford) described his project
with Martin Reinhard to better understand contaminant sequestration
in soil micropores.
Jennifer Field (OSU) spoke about her group's research to
improve the effectiveness of the single-well push-pull test
to monitor the effectiveness of bioremediation of TCE. She
also described research on substances that may be used as
surrogates for TCE in field experiments.
James Ingle (OSU) described his research on redox sensors.
He is developing spectrometric sensing devices to monitor
the redox status of new cultures in microcosm bottles and
Graduate students presented seventeen posters highlighting
their thesis research on projects related to the seven topics
Ken Williamson described the Technical Outreach Services
for Communities (TOSC) and Technical Assistance to Brownfields
Communities (TAB) programs. He illustrated TOSC and TAB's
role by describing a TOSC community in Santa Rosa, CA and
asking the audience to serve as mock-technical assistance
specialists. The audience had to review contaminant levels
and advise the community about whether a brownfields redevelopment
site was safe for children.
The meeting also included the first gathering of the Center's
Science Advisory Committee (SAC) and Outreach Advisory Committee
(OAC). The committees role is to provide oversight of the Center
over the five-year life of our grant. Our thanks to the committee
members -- we look forward to their insight and recommendations.
