Who We Are

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 donations like you. Learn how you can join.

Who We Are

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.

• Habitat restoration to revive ecosystems

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

Who We Are

'I used to think my voice didn't matter. Then I joined a citizen monitoring program and realized — my action prevents extinction. Now I'm inspiring others.' — Jennifer M., Water Guardian

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