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): PA5260013
System type: Community Water System
Population served: 3,841
Service connections: 1,875
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

MASONTOWN MUNI WATER WORKS is one of 298 community water systems in Pennsylvania in the 3,301 to 10,000 people size category, serving 3,841 people from surface water.

As of August 1, 2026, its federal record holds 186 entries between 1982 and 2026, all of which EPA lists as closed.

Of the 186, 170 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, volatile organic chemicals, and synthetic organic chemicals.
