Chloride and Our Water - Monitoring the Mix

In 2010, the MPCA more than doubled the number of waters that are listed as impaired for chloride (found in road salt). Too much salt results in costly damages and serious environmental consequences. The chloride in road salt enters our surface waters and groundwater after snow melts and is harmful to the fish, insects, and plants. While progress in Minnesota has been made in these areas, there is still much work to do in order to meet water quality standards and achieve a high level of road safety.
