Who We Are

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

This work is possible because of partners like you. Every contribution matters.

Who We Are

Pollution doesn't stop at your neighbor's fence — and our solutions don't either. We work across industries to solve problems at their source.

• Legal advocacy driving enforcement

Join thousands of environmental advocates pushing back for justice.

Who We Are

'Thirty years ago, this river was polluted. Thanks to this organization, native fish are returning. 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.
