Initiatives

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

This work is possible because of scientists like you. Your voice is essential.

Initiatives

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

• Legal advocacy driving stronger standards

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

'Thirty years ago, this river was polluted. Through their work, children can swim safely. I watch the difference daily.' — Dr. Robert L.

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