World Water Monitoring Challenge

Main Project Information
Goal Create world map of the health of water bodies.
Task Monitor your local water body.
Where Global, anywhere on the planet

World Water Monitoring Challenge is an international program that encourages citizen volunteers to monitor their local water bodies. An easy-to-use test kit enables everyone from children to adults to sample local water bodies for basic water quality parameters: temperature, acidity (pH), clarity (turbidity), and dissolved oxygen.

The results of current and past studies are shared with participating communities around the globe through the organization's online Data & Reports page.
