Chemical Controls Research

From August 8, 1990 (update #3)

Six chemical oxidants are being evaluated for their effectiveness in killing zebra mussels in their free-swimming larvae (veliger) stage this summer in a research project involving two separate western Lake Erie water intakes. The six chemicals are sodium hypochlorite, ferrous iron plus hydrogen peroxide, potassium permanganate, chlorine dioxide, chloramines and unionized ammonia. Three of these will be evaluated at each plant. Funded by the American Water Works Association (AWWA) Research Foundation, the study is being conducted by the City of Toledo (Ohio) water utility in cooperation with Prof. Peter Fraleigh of the University of Toledo and the City of Cleveland. The results of the project should be available this fall. For more information, contact Emerson Lomaquahu, AWWA Research Foundation, 6666 W. Quincy Ave., Denver, CO 80235, phone (303) 794-7711.

The Zebra Mussel Update was a 4- to 8-page quarterly national newsletter published by the University of Wisconsin Sea Grant Institute from May 1990 through May 1997. The ZMU documented the spread of the zebra mussel -- an exotic nuisance mussel -- through North America's freshwater environments, especially the Great Lakes, and on efforts to control it.
