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): SD4602301
System type: Community Water System
Population served: 45
Service connections: 14
Ownership: privately owned
Water source: groundwater (wells)

CEDAR GULCH 1 is one of 583 community water systems in South Dakota in the 500 or fewer people size category, serving 45 people from groundwater.

As of August 1, 2026, its federal record holds 34 entries between 2013 and 2019, all of which EPA lists as closed. Nothing has been added since 2019.

Of the 34, 30 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 Total Coliform Rules.
