MIDLOTHIAN is one of 225 community water systems in Illinois in the 10,001 to 100,000 people size category, serving 14,819 people from surface water.

As of August 1, 2026, its federal record holds 8 entries between 1992 and 2026, of which 1 remains open; none are health-based.

What is a Consumer Confidence Report?

A Consumer Confidence Report (CCR) is the annual drinking water quality report that community water systems must provide to the people they serve. 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. EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.
