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

PARKER WSD must publish a Consumer Confidence Report — the annual drinking water quality report covering calendar year 2026 — by July 1, 2027.

System facts

System ID (PWSID): CO0118040
System type: Community Water System
Population served: 75,949
Service connections: 20,005
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

PARKER WSD is among the 19 largest community water systems in Colorado, serving 75,949 people from surface water.

As of August 1, 2026, its federal record holds 96 entries between 1996 and 2024, all of which EPA lists as closed.

Of the 96, 94 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, the Stage 1 Disinfectants and Disinfection Byproducts Rule, and the Surface Water Treatment Rules.

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.
