MADISON, WI -- While salt keeps Wisconsin roads safe during the winter, using more than needed comes with a hefty price.
The Wisconsin Department of Natural Resources (DNR) and Wisconsin Salt Wise recognize this week, Jan. 11-15, as Wisconsin Salt Awareness Week. This is to remind residents of the negative impacts of salt and to provide best practices for salt usage.
Wisconsin Salt Wise will host daily livestreams on YouTube from 12:30-1 p.m., featuring experts on topics ranging from lake science to water softeners.
Property managers are welcome to attend a virtual Smart Salting Training Thursday, Jan. 14.
According to WI DNR, chlorides from salt are infiltrating lakes, streams and groundwater which have significant impacts like corrosion of bridges, roads and other infrastructure, and even impacts on pets.
In the early 2000s, the DNR measured about 600,000 tons of chlorides annually. By 2018, that number increased to nearly 800,000 tons per year.
Road salting brings a major result, but chlorides also enter Wisconsin waters because of water softeners and fertilizers.
