Our Mission

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

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

Our Mission

We believe that nature can heal if we restore what was lost. Our growing coalition shows that grassroots action works.

• Policy research driving enforcement

The water that flows through you connects you to 7 billion people — and billions more organisms. 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 harm. Now I'm leading others.' — Michael O., Volunteer

We believe that nature can heal if we remove barriers. Our 20-year track record shows that change happens.
