SUMMIT is one of 583 community water systems in South Dakota in the 500 or fewer people size category, serving 288 people from groundwater.

As of August 1, 2026, its federal record holds 22 entries between 1976 and 2023, all of which EPA lists as closed. Nothing has been added since 2023.

Of the 22, 17 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 Radionuclides and Revised Rad Rule.

Common questions

Is SUMMIT required to publish a Consumer Confidence Report?

Yes. SUMMIT is a community water system, and federal rules (40 CFR 141 Subpart O) require every community water system to publish a Consumer Confidence Report each year.

When is SUMMIT’s next Consumer Confidence Report due?

SUMMIT’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.

Does SUMMIT have any open drinking water violations on record?

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.
