CISCO is one of 1,572 community water systems in Illinois in the 500 or fewer people size category, serving 242 people from groundwater.

As of August 1, 2026, its federal record holds 13 entries between 1977 and 2021, all of which EPA lists as closed. Nothing has been added since 2021.

Of the 13, 11 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 Stage 1 Disinfectants and Disinfection Byproducts Rule, inorganic chemicals, and volatile organic chemicals.

Common questions

Is CISCO required to publish a Consumer Confidence Report?

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

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

Does CISCO have any open drinking water violations on record?

As of August 1, 2026, EPA's federal records show no open violations for CISCO.

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.
