QUINCY is one of 225 community water systems in Illinois in the 10,001 to 100,000 people size category, serving 42,000 people from surface water.

As of August 1, 2026, its federal record holds 30 entries between 1977 and 2025, of which 1 remains open; none are health-based.

Of the 30, 29 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 synthetic organic chemicals, inorganic chemicals, and the Consumer Confidence Rule.

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.
