Our Mission

Water doesn't recognize borders — and neither do the threats it faces. Our international teams work year-round 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.

• Policy research driving stronger standards

Join thousands of water guardians pushing back for justice.

Our Mission

'Thirty years ago, this river was dying. 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 remove barriers. Our 20-year track record shows that change happens.
