Madison’s waterways are clearly impacted by winter salt use. Steadily increasing levels of chlorides from deicers have been found in all of Madison's Lakes, and in our wells.
Odana Pond, at the western end of the Lake Wingra watershed, is listed as an impaired water due to very high chloride levels. Most of the salt is from highways, streets and parking lots, but home use also contributes.
