Our Mission

Water doesn't recognize borders — and neither do the threats it faces. Our international teams work tirelessly to protect it.

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

Our Mission

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.

• Long-term scientific monitoring of water quality shifts

The water that flows through you connects you to 7 billion people — and countless ecosystems. Stand with us.

Our Mission

'I used to think my voice didn't matter. Then I joined a citizen monitoring program and realized — my voice prevents extinction. Now I'm leading 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 rebuild what was lost.
