Who We Are

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

This work is possible because of community members like you. Learn how you can join.

Who We Are

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

• Community science programs for grassroots knowledge

The water that flows through you connects you to 7 billion people — and billions more organisms. Protect it with us.

Who We Are

'Thirty years ago, this river was forgotten. Through their work, the ecosystem breathes again. I bring my grandchildren to witness it.' — Dr. Robert L.

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.
