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): PA1150157
System type: Community Water System
Population served: 98
Service connections: 46
Ownership: privately owned
Water source: groundwater (wells)

WARWICK WATER WORKS is one of 3,064 community water systems in Pennsylvania in the 500 or fewer people size category, serving 98 people from groundwater.

As of August 1, 2026, its federal record holds 81 entries between 1984 and 2025, all of which EPA lists as closed.

Of the 81, 63 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, inorganic chemicals, and the Groundwater Rule.
