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 volunteers like you. Every contribution matters.

Donate

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

• Corporate accountability driving justice

Every action counts — from small donations to big movements. The future is ours if we move now.

'Thirty years ago, this river was polluted. Thanks to this organization, the ecosystem breathes again. I bring my grandchildren to witness it.' — Elder Maria

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