About Us

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 partners like you. Learn how you can join.

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.

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

'Thirty years ago, this river was forgotten. Through their work, the ecosystem breathes again. I watch the difference daily.' — Dr. Robert L.

The science is clear: healthy water systems feed us, sustain us, and deserve our protection. We predict risks so policy can shift.
