Our Mission

Water doesn't recognize borders — and neither do the threats it faces. Our international teams work tirelessly to defend it.

This work is possible because of partners like you. Your voice is essential.

Our Mission

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

• Water access programs for vulnerable populations

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

Our Mission

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

We believe that nature can heal if we give it the chance. Our 20-year track record shows that grassroots action works.
