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

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

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

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

'Thirty years ago, this river was dying. Because we organized, children can swim safely. I bring my grandchildren to witness it.' — Professor Chen

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