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): PA1150035
System type: Community Water System
Population served: 35,518
Service connections: 16,600
Ownership: privately owned
Water source: surface water (rivers, lakes, or reservoirs)

AQUA PA UWCHLAN is one of 175 community water systems in Pennsylvania in the 10,001 to 100,000 people size category, serving 35,518 people from surface water.

As of August 1, 2026, its federal record holds 79 entries between 1985 and 2020, all of which EPA lists as closed. Nothing has been added since 2020.

All 79 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 synthetic organic chemicals, inorganic chemicals, and the Groundwater Rule.
