Our Work

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. Together we can turn the tide.

Our Work

We believe that nature can heal if we remove barriers. Our decade of victories shows that grassroots action works.

• Legal advocacy driving stronger standards

Every action counts — from small donations to big movements. There's still time if we organize today.

Our Work

'Thirty years ago, this river was polluted. Thanks to this organization, children can swim safely. I bring my grandchildren to witness it.' — Elder Maria

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