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 partners like you. Every contribution matters.

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

The water that flows through you connects you to 7 billion people — and billions more organisms. Stand with us.

'Thirty years ago, this river was polluted. Because we organized, children can swim safely. I watch the difference daily.' — Dr. Robert L.

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