OGLESBY is one of 248 community water systems in Illinois in the 3,301 to 10,000 people size category, serving 4,500 people from groundwater.
As of August 1, 2026, its federal record holds 48 entries between 1993 and 2025, of which 1 remains open; none are health-based.
Of the 48, 42 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, the Lead and Copper Rule, and the Consumer Confidence Rule.

Common questions
Is OGLESBY required to publish a Consumer Confidence Report?
- Yes. OGLESBY is a community water system, and federal rules (40 CFR 141 Subpart O) require every community water system to publish a Consumer Confidence Report each year.
When is OGLESBY’s next Consumer Confidence Report due?
- OGLESBY’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does OGLESBY have any open drinking water violations on record?
- As of August 1, 2026, EPA's federal records show 1 item for OGLESBY that is open and awaiting resolution. None are health-based violations — open items of this kind are most often monitoring or reporting requirements, not water-safety findings.
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.
