WINSLOW is one of 1,572 community water systems in Illinois in the 500 or fewer people size category, serving 350 people from groundwater.
As of August 1, 2026, its federal record holds 27 entries between 1977 and 2026, of which 1 health-based item remains open, alongside 6 other open entries.
Of the 27, 14 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 the Lead and Copper Rule, the Total Coliform Rules, 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.
