MAPLETON is one of 1,572 community water systems in Illinois in the 500 or fewer people size category, serving 261 people from groundwater.
As of August 1, 2026, its federal record holds 29 entries between 1977 and 2025, of which 2 remain open; none are health-based.
Of the 29, 5 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 Radionuclides and Revised Rad Rule, the Consumer Confidence Rule, and the Total Coliform Rules.

Common questions
Is MAPLETON required to publish a Consumer Confidence Report?
- Yes. MAPLETON 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 MAPLETON’s next Consumer Confidence Report due?
- MAPLETON’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does MAPLETON have any open drinking water violations on record?
- As of August 1, 2026, EPA's federal records show 2 items for MAPLETON that are 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.
