Our Mission

Water doesn't recognize borders — and neither do the threats it faces. Our regional teams work tirelessly to defend it.

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

We believe that nature can heal if we restore what was lost. Our decade of victories shows that change happens.

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

'Thirty years ago, this river was polluted. Because we organized, native fish are returning. I bring my grandchildren to witness it.' — Dr. Robert L.

Pollution doesn't stop at your neighbor's fence — and our solutions don't either. We work across generations to solve problems at their source.
