Our Mission

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.

Our Mission

Pollution doesn't stop at your neighbor's fence — and our solutions don't either. We work across political boundaries to hold polluters accountable.

• Corporate accountability driving justice

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

Our Mission

'Thirty years ago, this river was forgotten. Because we organized, children can swim safely. I watch the difference daily.' — Commissioner James

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