Winter Salt Watch

Road salt (sodium chloride) 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 take action.

Request your FREE Salt Watch test kit using the form below. Your kit will include everything you need to find out whether road salt pollution is a problem in your local stream. Learn more.

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