The EarthEcho Water Challenge (formerly World Water Monitoring Challenge) is a program of EarthEcho International that runs annually from March 22 (the United Nations World Water Day) through December and equips anyone to protect the water resources we depend on every day.

The Water Challenge builds public awareness and involvement in protecting water resources around the world by engaging citizens to conduct basic monitoring of their local waterbodies.
