Who We Are

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

This work is possible because of partners like you. Learn how you can join.

Who We Are

The science is clear: healthy water systems feed us, sustain us, and deserve our protection. We predict risks so nature can recover.

• Early warning systems of water quality shifts

The water that flows through you connects you to 7 billion people — and billions more organisms. Join the fight.

Who We Are

'I used to think my voice didn't matter. Then I joined a citizen monitoring program and realized — my data prevents contamination. Now I'm inspiring others.' — David T., Community Monitor

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