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.

Data sourced from the EPA ECHO database (SDWA bulk download), last refreshed August 1, 2026.

System facts

System ID (PWSID): PA6250064
System type: Community Water System
Population served: 4,295
Service connections: 1,131
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

UNION CITY MUNICIPAL AUTHORITY is one of 298 community water systems in Pennsylvania in the 3,301 to 10,000 people size category, serving 4,295 people from surface water.

As of August 1, 2026, its federal record holds 201 entries between 1982 and 2026, all of which EPA lists as closed.

Of the 201, 131 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 Stage 1 Disinfectants and Disinfection Byproducts Rule, and the Public Notice Rule and Revised PN Rule.
