World Water Monitoring Challenge (WWMC) is an international education and outreach program that builds public awareness and involvement in protecting water resources around the world by engaging citizens to conduct basic monitoring of their local water bodies.

Water monitoring provides basic information about streams, lakes, estuaries and coastal waters to provide a better understanding of whether they are safe enough to swim in, fish from, or use for drinking or irrigation purposes.

A test kit enables youth and adults to sample local water bodies for a core set of water quality parameters including temperature, acidity (pH), clarity (turbidity) and dissolved oxygen (DO). Results are shared with participating communities around the globe through the WWMC Web site.

WWMC is a program of EarthEcho International.  Founded by explorer and environmental advocate Philippe Cousteau, Jr., EarthEcho International is a leading environmental education organization dedicated to building and activating a new generation of youth who will solve the most critical problems facing people and the planet.

The project runs annually from March 22 to December 31.
