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.

HILLSIDE MHP Water System

Consumer Confidence Report status

HILLSIDE 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 4 items for HILLSIDE MHP that are 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): OH7002012
System type: Community Water System
Population served: 69
Service connections: 64
Ownership: privately owned
Water source: groundwater (wells)

HILLSIDE MHP is one of 1,399 community water systems in Ohio in the 500 or fewer people size category, serving 69 people from groundwater.

As of August 1, 2026, its federal record holds 56 entries between 1984 and 2026, of which 4 remain open; none are health-based.

Of the 56, 19 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 Surface Water Treatment Rules, the Total Coliform Rules, and the Consumer Confidence Rule.
