Volunteer

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. Your voice is essential.

Pollution doesn't stop at your neighbor's fence — and our solutions don't either. We work across political boundaries to hold polluters accountable.

• Long-term scientific monitoring of water quality shifts

The water that flows through you connects you to 7 billion people — and countless ecosystems. Protect it with us.

'I used to think my voice didn't matter. Then I joined a citizen monitoring program and realized — my data prevents extinction. Now I'm inspiring others.' — Michael O., Watershed Advocate

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