Who We Are

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. Your voice is essential.

Who We Are

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. Protect it with us.
