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.

CLARKS MHP Water System

Consumer Confidence Report status

CLARKS MHP 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 CLARKS MHP 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): IL2015425
System type: Community Water System
Population served: 90
Service connections: 36
Ownership: privately owned
Water source: groundwater (wells)

CLARKS MHP is one of 1,572 community water systems in Illinois in the 500 or fewer people size category, serving 90 people from groundwater.

As of August 1, 2026, its federal record holds 77 entries between 1980 and 2025, of which 1 remains open; none are health-based.

Of the 77, 68 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 inorganic chemicals.

Common questions

Is CLARKS MHP required to publish a Consumer Confidence Report?: Yes. CLARKS MHP 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 CLARKS MHP’s next Consumer Confidence Report due?: CLARKS MHP’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does CLARKS MHP have any open drinking water violations on record?: As of August 1, 2026, EPA's federal records show 1 item for CLARKS MHP 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.
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.
