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.

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

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

'Thirty years ago, this river was polluted. Because we organized, children can swim safely. I work alongside their team.' — Dr. Robert L.

We believe that nature can heal if we give it the chance. Our growing coalition shows what's possible.
