CALHOUN Water System
Consumer Confidence Report status
CALHOUN must publish a Consumer Confidence Report — the annual drinking water quality report covering calendar year 2026 — by July 1, 2027.
As of August 1, 2026, EPA's federal records show no open violations for CALHOUN.
Data sourced from the EPA ECHO database (SDWA bulk download), last refreshed August 1, 2026. This is a record-keeping and public-information tool — it does not replace Illinois’s official records. Always confirm current status with Illinois before making decisions based on this information.

CALHOUN is one of 1,572 community water systems in Illinois in the 500 or fewer people size category, serving 172 people from groundwater.
As of August 1, 2026, its federal record holds 64 entries between 1977 and 2026, all of which EPA lists as closed.
Of the 64, 59 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 Total Coliform Rules, and the Lead and Copper Rule.

Common questions
Is CALHOUN required to publish a Consumer Confidence Report?
- Yes. CALHOUN 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 CALHOUN’s next Consumer Confidence Report due?
- CALHOUN’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does CALHOUN have any open drinking water violations on record?
- As of August 1, 2026, EPA's federal records show no open violations for CALHOUN.
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.
