Our Work

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

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

Our Work

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

• Emergency support for crisis zones

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

Our Work

'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 leading others.' — Michael O., Community Monitor

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.
