WHITE ROCK COLONY Water System
Consumer Confidence Report status
WHITE ROCK COLONY 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 WHITE ROCK COLONY.
Data sourced from the EPA ECHO database (SDWA bulk download), last refreshed August 1, 2026. This is a record-keeping and public-information tool — it does not replace South Dakota’s official records. Always confirm current status with South Dakota before making decisions based on this information.

WHITE ROCK COLONY is one of 583 community water systems in South Dakota in the 500 or fewer people size category, serving 108 people from groundwater.
As of August 1, 2026, its federal record holds 61 entries between 1990 and 2013, all of which EPA lists as closed. Nothing has been added since 2013.
Of the 61, 51 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.

Common questions
Is WHITE ROCK COLONY required to publish a Consumer Confidence Report?
- Yes. WHITE ROCK COLONY 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 WHITE ROCK COLONY’s next Consumer Confidence Report due?
- WHITE ROCK COLONY’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does WHITE ROCK COLONY have any open drinking water violations on record?
- As of August 1, 2026, EPA's federal records show no open violations for WHITE ROCK COLONY.
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.
