What is a Consumer Confidence Report?

It lists the contaminants detected in the system’s water during the year, where the water comes from, and how the results compare with federal limits.

CREVE COEUR is one of 248 community water systems in Illinois in the 3,301 to 10,000 people size category, serving 4,934 people from groundwater.
