SIPHON HILL WATER ASSOCIATION Water System
Consumer Confidence Report status
SIPHON HILL WATER ASSOCIATION 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 SIPHON HILL WATER ASSOCIATION.
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.

SIPHON HILL WATER ASSOCIATION is one of 583 community water systems in South Dakota in the 500 or fewer people size category, serving 68 people from groundwater.
As of August 1, 2026, its federal record holds 77 entries between 1976 and 2001, all of which EPA lists as closed. Nothing has been added since 2001.
Of the 77, 66 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 synthetic organic chemicals.

When is SIPHON HILL WATER ASSOCIATION’s next Consumer Confidence Report due?
- SIPHON HILL WATER ASSOCIATION’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does SIPHON HILL WATER ASSOCIATION 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.
