About Us

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

This work is possible because of volunteers like you. Every contribution matters.

About Us

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

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

About Us

'I used to think my voice didn't matter. Then I joined a citizen monitoring program and realized — my action prevents crisis. Now I'm inspiring others.' — Michael O., Community Monitor
