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.

MARK Water System

Consumer Confidence Report status

MARK 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 1 item for MARK that is 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.

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): IL1550250
System type: Community Water System
Population served: 555
Service connections: 265
Ownership: local government
Water source: groundwater (wells)

MARK is one of 773 community water systems in Illinois in the 501 to 3,300 people size category, serving 555 people from groundwater.

As of August 1, 2026, its federal record holds 32 entries between 1981 and 2026, of which 1 remains open; none are health-based.

Of the 32, 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 Radionuclides and Revised Rad Rule, the Lead and Copper Rule, and the Total Coliform Rules.
