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.

System facts

System ID (PWSID): PA1460030
System type: Community Water System
Population served: 130
Service connections: 130
Ownership: privately owned
Water source: groundwater (wells)

OAK GROVE PARK MHP is one of 3,064 community water systems in Pennsylvania in the 500 or fewer people size category, serving 130 people from groundwater.

As of August 1, 2026, its federal record holds 154 entries between 2000 and 2024, all of which EPA lists as closed.

Of the 154, 153 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 Radionuclides and Revised Rad Rule, and the Stage 2 Disinfectants and Disinfection Byproducts Rule.
