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.)

NOTE: Our supply of free Salt Watch kits has been disbursed. You may complete this form and be added to a waitlist. We expect to resupply before September 1, 2023.
