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

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

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

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

'Thirty years ago, this river was polluted. Thanks to this organization, native fish are returning. I work alongside their team.' — Elder Maria

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