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.

HANOVER MUNI WATER WORKS Water System

Consumer Confidence Report status

HANOVER MUNI WATER WORKS must publish a Consumer Confidence Report — the annual drinking water quality report covering calendar year 2026 — by July 1, 2027.

As of August 1, 2026, EPA's federal records show no open violations for HANOVER MUNI WATER WORKS.

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

System facts

System ID (PWSID): PA7670076
System type: Community Water System
Population served: 40,900
Service connections: 18,027
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

HANOVER MUNI WATER WORKS is one of 175 community water systems in Pennsylvania in the 10,001 to 100,000 people size category, serving 40,900 people from surface water.

As of August 1, 2026, its federal record holds 112 entries between 1990 and 2024, all of which EPA lists as closed.

Of the 112, 102 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 Surface Water Treatment Rules, and synthetic organic chemicals.
