Sand Filters Option Reviewed

From February 19, 1992 (update #12)

Several types of sand filter systems and the pros and cons of using them to keep zebra mussels out of water intakes are discussed in a new pamphlet available from the Great Lakes Sea Grant Network. Written by Wisconsin Sea Grant Coastal Engineering Specialist Philip Keillor, the three-page illustrated pamphlet notes how sand-filtered intakes ended the zebra mussel problem for Hamburg, Germany, in the 1880s, and it describes several of the sand filtration systems currently in use around the Great Lakes. Single copies of "Sand Filter Intakes Could Safeguard Vital Water-Supply Systems from Zebra Mussels" are available free of charge from most Illinois- Indiana, Michigan, Minnesota, New York, Ohio and Wisconsin Sea Grant offices.

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.
