Who We Are

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

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

Who We Are

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

• Policy research driving stronger standards

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

Who We Are

'Thirty years ago, this river was forgotten. Thanks to this organization, native fish are returning. 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 propose solutions so nature can recover.
