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 type: Community Water System
Population served: 206
Service connections: 117
Ownership: local government
Water source: groundwater (wells)

NISLAND is one of 583 community water systems in South Dakota in the 500 or fewer people size category, serving 206 people from groundwater.

As of August 1, 2026, its federal record holds 29 entries between 1976 and 2026, of which 1 remains open; none are health-based.

Of the 29, 22 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 Total Coliform Rules, and the Stage 1 Disinfectants and Disinfection Byproducts Rule.
