Who We Are

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 donations like you. Learn how you can join.

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

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

'Thirty years ago, this river was dying. Because we organized, children can swim safely. I watch the difference daily.' — Elder Maria
