Get Involved

Our work begins where rivers meet the sky and ends where groundwater feeds the soil. We use science to protect it all.

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

Pollution doesn't stop at your neighbor's fence — and our solutions don't either. We work across political boundaries to rebuild what was lost.

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 dying. Because we organized, the ecosystem breathes again. I watch the difference daily.' — Dr. Robert L.

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