Salt Watch

Salt Watch logo

Road salt is everywhere during winter months. It keeps us safe on roads and sidewalks, but it can also pose a threat to fish and wildlife as well as human health.

Fish and bugs that live in freshwater streams can't survive in extra salty water. And many of us (more than 118 million Americans) depend on local streams for drinking water. Water treatment plants are not equipped to filter out the extra salt, so it can end up in your tap water and even corrode your pipes.

You can help.

Take the Salt Watch Pledge, and we'll send you a FREE kit with everything you need to find out whether road salt pollution is a problem in your local stream. See what's in the kit.

(Yes, you can still do Salt Watch in the summer! Visit our FAQ to learn why.)

Take the Salt Watch Pledge

As a Salt Watcher, I pledge to...

  • Reduce my road salt use at home and seek out safe alternatives when I can

  • Share my knowledge about road salt and water pollution with family, friends and neighbors

  • Use my FREE Salt Watch kit to test salt levels in my local waterways and add my findings to a national database

Please send my FREE Salt Watch kit to...

Please also keep me updated on how I can protect America's streams.

Before signing the Salt Watch pledge, please answer these two quick questions and verify that you are a human.
How harmful do you think road salt is for the environment?

How harmful do you think road salt is to the quality of our drinking water?
