Who We Are

Water doesn't recognize borders — and neither do the threats it faces. Our local teams work year-round to defend it.

This work is possible because of community members 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.

• Early warning systems of water quality shifts

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

Who We Are

'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.' — Jennifer M., Volunteer

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