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.

Consumer Confidence Report status

MONTGOMERY WATER AUTHORITY 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 MONTGOMERY WATER AUTHORITY.

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

System facts

System ID (PWSID): PA4410161
System type: Community Water System
Population served: 2,700
Service connections: 813
Ownership: local government
Water source: groundwater (wells)

MONTGOMERY WATER AUTHORITY is one of 757 community water systems in Pennsylvania in the 501 to 3,300 people size category, serving 2,700 people from groundwater.

As of August 1, 2026, its federal record holds 138 entries between 1993 and 2026, all of which EPA lists as closed.

Of the 138, 119 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, volatile organic chemicals, and the Radionuclides and Revised Rad Rule.
