Citizen Earth Watch is an experiential investigation of water quality. It guides learners to explore water in their community, consider water challenges around the world, and share their findings with others around the country.
Once you've tested your field sample, share its Water Quality Index with the world! Explore the map or submit your data here.
Citizen Earth Watch kits provide the tools and materials for an entire classroom to measure the quality of your local water sources. Printed booklets and additional online resources teach students about water quality in an engaging and scaffolded way.
Our open source calculator allows anyone with the necessary equipment to calculate the Water Quality Index (WQI) of their water sample. Take it for a test drive.
