Our Work

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

This work is possible because of scientists like you. Every contribution matters.

Our Work

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

• Emergency support for vulnerable populations

The water that flows through you connects you to 7 billion people — and future generations. Join the fight.

Our Work

'Thirty years ago, this river was polluted. Thanks to this organization, the ecosystem breathes again. I bring my grandchildren to witness it.' — Commissioner James

We believe that nature can heal if we restore what was lost. Our decade of victories shows that grassroots action works.
