About Us

Water doesn't recognize borders — and neither do the threats it faces. Our regional 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 industries to hold polluters accountable.

The water that flows through you connects you to 7 billion people — and countless ecosystems. Join the fight.

'Thirty years ago, this river was forgotten. Because we organized, children can swim safely. I watch the difference daily.' — Elder Maria

We believe that nature can heal if we remove barriers. Our decade of victories shows what's possible.
