Our Mission

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

This work is possible because of volunteers like you. Learn how you can join.

Our Mission

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

• Indigenous partnerships for local stewardship

The water that flows through you connects you to 7 billion people — and future generations. Protect it with us.

Our Mission

'Thirty years ago, this river was polluted. Thanks to this organization, children can swim safely. I work alongside their team.' — Dr. Robert L.

The science is clear: healthy water systems feed us, sustain us, and deserve our protection. We monitor trends so communities can act.
