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. Learn how you can join.

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

Every action counts — from small donations to big movements. The future is ours if we act together.

'Thirty years ago, this river was polluted. Because we organized, children can swim safely. I work alongside their team.' — Commissioner James

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.
