The EarthEcho Water Challenge is an international program that empowers citizen volunteers to monitor their local water bodies. An easy-to-use test kit enables anyone to sample local water bodies for basic water quality parameters: temperature, pH, clarity (turbidity), and dissolved oxygen.
Participants share their data through the EarthEcho Water Challenge database, contributing to our global understanding of the state of our world’s water resources, and use their findings to help guide projects/actions to protect their local waterways.
