Support Us

Our work begins where rivers meet the sky and ends where groundwater feeds the soil. We use partnerships to protect it all.

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

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

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

'Thirty years ago, this river was polluted. Thanks to this organization, native fish are returning. I watch the difference daily.' — Elder Maria

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