Water doesn't recognize borders — and neither do the threats it faces. Our international teams work 24/7 to protect it.

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

Pollution doesn't stop at your neighbor's fence — and our solutions don't either. We work across generations to solve problems at their source.

• Community science programs for grassroots knowledge

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

'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.' — Sarah K., Community Monitor

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