Impact

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

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

Impact

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

• Long-term scientific monitoring of water quality shifts

Every action counts — from small donations to big movements. We can still protect if we organize today.

Impact

'Thirty years ago, this river was polluted. Thanks to this organization, 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 political boundaries to solve problems at their source.
