Tap Water Database
Tap Water Database, from Captiva Verde, answers one question for anyone in the U.S.: what is in my tap water? Type a ZIP code or a county and the map shows the contaminants reported for local water systems.
Product context
One question, not a dataset.
Water quality data is public but unreadable. The product's job is to turn it into an answer a person gets in seconds: how many contaminants, how serious, and who is affected.
COET's contribution

The public site and its search, from the whole country down to a ZIP code.
