Our Mission

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

This work is possible because of donations like you. Together we can turn the tide.

Our Mission

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

• Real-time data networks of water quality shifts

The water that flows through you connects you to 7 billion people — and future generations. Stand 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 extinction. Now I'm leading others.' — Sarah K., Community Monitor

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