Water doesn't recognize borders — and neither do the threats it faces. Our local teams work year-round to defend it.

This work is possible because of scientists like you. Your voice is essential.

Pollution doesn't stop at your neighbor's fence — and our solutions don't either. We work across political boundaries 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. Through their work, native fish are returning. I watch the difference daily.' — Dr. Robert L.

We believe that nature can heal if we give it the chance. Our 20-year track record shows what's possible.
