AQUA ILLINOIS-SKYLINE (NORTHERN) Water System
Consumer Confidence Report status
AQUA ILLINOIS-SKYLINE (NORTHERN) 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 AQUA ILLINOIS-SKYLINE (NORTHERN).
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.

AQUA ILLINOIS-SKYLINE (NORTHERN) is one of 773 community water systems in Illinois in the 501 to 3,300 people size category, serving 1,200 people from groundwater.
As of August 1, 2026, its federal record holds 171 entries between 1977 and 2025, all of which EPA lists as closed.
All 171 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 the Total Coliform Rules.

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.
