MADISON, Wis. (WRN) — Wisconsin’s municipal wells have too much sodium.
The Journal Sentinel reports that much of that contamination comes from road salt. The Department of Natural Resources reports that 36 percent of the public wells tested for sodium are above the limits for people on low sodium diets. That can lead to high blood pressure and other health issues.
Many communities have already been cutting their salt usage, and the DNR reminds you that only a coffee cup’s worth of salt can handle a residential driveway.
