Dr. Ken Hudnell, adjunct associate professor in the Department of Environmental Sciences and Engineering at the University of North Carolina (Chapel Hill), is the first speaker for the University of Wisconsin-Fox Valley’s 2012-2013 Scholars Series. Hudnell’s presentation takes place in Perry Hall on the UWFox campus, from noon to 1:00 p.m. from noon to 1:00 p.m. on Monday, September 17, 2012.
According to Hudnell, “Water bodies that no longer provide their designated uses pursuant to Clean Water Act (CWA) Section 303(d) must be listed as impaired. Impairments are caused by excessive concentrations of nutrients, toxic substances, and pathogens. Approximately 44% of river and stream miles, and 64% of lake and reservoir acres are listed as impaired. The primary cause of impairment is excessive nutrient concentrations that cause eutrophication, characterized by the overabundance of harmful algae.”
Hudnell explained, “A shift in policy to a combination of waterbody and watershed management will provide the flexibility to optimize Nutrient Management Strategies so that each impaired waterbody can be treated in the most effective and cost efficient manner. Funding should be available from CWA 319 grants and the state revolving-loan program. This ecologically-based, systems-approach to freshwater management can reverse the trend of increasing eutrophication, Cyanobacterial harmful algal blooms (HABs), occurrence, and impairment by other pollutants, restore water quality and designated uses in the near term, and ensure a sustainable supply of useable freshwater.”
Hudnell has undergraduate degrees in chemistry and psychology, a doctorate in neurobiology and biological psychology, and post-doctoral training in toxicology. He served as a neurotoxicologist at the U.S. E.P.A. for 23 years where he conducted research on human health effects caused by exposures to environmental pollutants. His focus on biotoxins in recent years led an interagency effort to address the problem of freshwater harmful algal blooms and is editor and co-author of a book on that topic.
The Scholars Series is free and open to the public with unreserved seating. For more information, contact the UWFox Office of University Relations, 920-832-2611 or email firstname.lastname@example.org.
