"A Treatment System for Groundwater Contamination — How Research at Oregon State University is Contributing to Sustainable and Passive Remediation Methods" presented by Lewis Semprini, Distinguished Professor of Environmental Engineering. Contamination of groundwater by volatile organic compounds is a widespread problem throughout the United States. Complex mixtures of chlorinated solvents and emerging contaminants such as 1,4-dioxane are of increasing concern. This talk discusses ongoing research at Oregon State University to develop more sustainable and passive remediation methods.
