NORTH CHICAGO is one of 225 community water systems in Illinois in the 10,001 to 100,000 people size category, serving 16,813 people from surface water.

As of August 1, 2026, its federal record holds 23 entries between 1977 and 2025, of which 1 remains open; none are health-based.

Of the 23, 17 are monitoring and reporting requirements — the category that accounts for about four in five of all violations in EPA's national dataset — rather than findings about the water itself. The record involves volatile organic chemicals, the Lead and Copper Rule, and the Stage 2 Disinfectants and Disinfection Byproducts Rule.

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.
