Who We Are

Water doesn't recognize borders — and neither do the threats it faces. Our regional teams work 24/7 to protect 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 political boundaries to solve problems at their source.

• Real-time data networks of water quality shifts

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

Who We Are

'Thirty years ago, this river was forgotten. Thanks to this organization, native fish are returning. I work alongside their team.' — Commissioner James

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