Melted ice and snow carry all that chloride into rivers, lakes and streams.
Here’s why that’s a problem and how you can help.
Fifty Minnesota lakes and streams are now on the state’s impaired waters list because of too much chloride, mainly from road salt. Excess chloride has widespread implications — everything from affecting aquatic life reproduction to corroding our infrastructure to health problems for humans. MPR News takes a deep dive into this threat and what’s being done to address it.
Here’s an interesting take on road salt from Ross Marchand, writing for the conservative online publication The Federalist. He insists that as policymakers consider infrastructure reform, they need to think about road salt’s direct and indirect effects on health, infrastructure and the environment.

Here’s a story we read with interest from Orleans, Vermont, where contamination of wells from road salt is resulting in the need for a new water line. The state is kicking in money to help pay for it, but residents want the state to fully finance it, as they blame road salt from a state DOT salt barn for causing the problem.
While departments of transportation in the Midwest and Northeast have been scaling back their use of road salt to limit chloride pollution in lakes, streams and rivers, the Oregon Department of Transportation has felt forced to go in a different direction. ODOT previously prohibited use of road salt for many reasons, including potential environmental harm. But a crippling ice storm in 2016 compelled it to change its tune.
As the potential impacts of excess road salt use on bodies of water and aquatic life become clearer, many state and local agencies are trying to use less. Alternatives like beet juice, and beer can also have undesirable environmental effects, but maybe the trade-off is worthwhile?

Minnesotans are a hardy bunch. Here, hockey is an outdoor sport and it takes more than six inches to trigger a snow day. But can Minnesotans channel that same “bold north” mentality to defend the state’s waters from chloride pollution?
