EarthEcho Water Challenge

The EarthEcho Water Challenge (formerly World Water Monitoring Challenge) is an international program 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 EarthEcho 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.
