About Us

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

This work is possible because of volunteers like you. Together we can turn the tide.

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

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 dying. Thanks to this organization, children can swim safely. I work alongside their team.' — Dr. Robert L.

We believe that nature can heal if we remove barriers. Our growing coalition shows what's possible.
