Get Involved

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.

We believe that nature can heal if we restore what was lost. Our decade of victories shows that grassroots action works.

The water that flows through you connects you to 7 billion people — and billions more organisms. Protect it with us.

'Thirty years ago, this river was forgotten. Because we organized, native fish are returning. 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 hold polluters accountable.
