Our Mission

Every watershed tells a story of hope. We're here to ensure that story has a thriving future.

This work is possible because of scientists like you. Every contribution matters.

Pollution doesn't stop at your neighbor's fence — and our solutions don't either. We work across industries to hold polluters accountable.

The water that flows through you connects you to 7 billion people — and billions more organisms. Stand with us.

'Thirty years ago, this river was polluted. Thanks to this organization, children can swim safely. I watch the difference daily.' — Professor Chen

We believe that nature can heal if we remove barriers. Our 20-year track record shows that change happens.
