Is BYRON required to publish a Consumer Confidence Report?

Yes. BYRON 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 BYRON’s next Consumer Confidence Report due?

BYRON’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.

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.

BYRON Water System

Consumer Confidence Report status

BYRON 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 BYRON.

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.

System facts

System ID (PWSID): IL1410100
System type: Community Water System
Population served: 3,784
Service connections: 2,081
Ownership: local government
Water source: groundwater (wells)

BYRON is one of 248 community water systems in Illinois in the 3,301 to 10,000 people size category, serving 3,784 people from groundwater.

As of August 1, 2026, its federal record holds 102 entries between 1977 and 2022, all of which EPA lists as closed. Nothing has been added since 2022.

Of the 102, 97 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, volatile organic chemicals, and inorganic chemicals.

Common questions

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