Grant received to research sediments
September 3, 2008

PULLMAN – A group of WSU researchers has received a $350,000 grant from the M. J. Murdock Charitable Trust to better understand the effects of contaminated lake and river sediments on human and ecological health.


Led by Jeffrey L. Ullman, assistant professor in Biological Systems Engineering, the grant establishes the Sediment Analysis Laboratory to carefully identify and measure pollutants, including heavy metals and organic compounds. The researchers will also be looking at microbial-contaminant interactions and pollutant impacts on fish and wildlife.


“Depending on the chemicals, interactions can result in synergistic, additive or … » More …

Role of microorganisms studied in moving, cleaning sediment
October 15, 2004

Brent Peyton and Rajesh Sani, researchers in the Center for Multiphase Environmental Research, received a 4-year, $1.2 million grant for a project to characterize indigenous microorganisms in the metal-contaminated sediments of Lake Coeur d’Alene and to analyze their role in the transport of metals through the environment. The work, sponsored by the National Science Foundation’s Biocomplexity Program, could someday be used to better predict metal transport processes in contaminated sediments and improve bioremediation strategies. A long history of mining in the Northwest has led to high levels of heavy metals in the sediments of some area lakes and rivers. However, microorganisms that live in these … » More …
