Our Mission

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

This work is possible because of donations like you. Together we can turn the tide.

Our Mission

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

• Real-time data networks of water quality shifts

The water that flows through you connects you to 7 billion people — and future generations. Protect it with us.

Our Mission

'I used to think my voice didn't matter. Then I joined a citizen monitoring program and realized — my data prevents contamination. Now I'm training others.' — David T., Watershed Advocate

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.
