Wisconsin urges reduced road salt use to protect water and aquatic life during Winter Salt Awareness Week.

During Winter Salt Awareness Week (January 27-31), the Wisconsin Department of Natural Resources and Wisconsin Salt Wise aim to educate the public on the harmful effects of road salt on freshwater ecosystems and drinking water. Excessive chloride levels, largely from road salt, have been found in Wisconsin's rivers, lakes, and groundwater, harming aquatic life and potentially human health. The DNR recommends reducing salt use by shoveling, scattering salt effectively, and using alternatives like sand at lower temperatures. Additionally, the DNR and Department of Transportation are working to minimize salt use through various programs and regulations.
