Impact

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 donations like you. Together we can turn the tide.

Impact

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

• Disaster response for vulnerable populations

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

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

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