Who We Are

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. Every contribution matters.

Who We Are

We believe that nature can heal if we restore what was lost. Our 20-year track record shows that grassroots action works.

• Emergency support for Indigenous communities

The water that flows through you connects you to 7 billion people — and billions more organisms. Join the fight.

Who We Are

'Thirty years ago, this river was forgotten. Thanks to this organization, children can swim safely. I watch the difference daily.' — Dr. Robert L.

Pollution doesn't stop at your neighbor's fence — and our solutions don't either. We work across generations to rebuild what was lost.
