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.

COLONIAL HILLS MHP Water System

Consumer Confidence Report status

COLONIAL HILLS 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 COLONIAL HILLS 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 Ohio’s official records. Always confirm current status with Ohio before making decisions based on this information.

System facts

System ID (PWSID): OH7000312
System type: Community Water System
Population served: 185
Service connections: 77
Ownership: privately owned
Water source: groundwater (wells)
