PRESHO is one of 583 community water systems in South Dakota in the 500 or fewer people size category, serving 472 people from surface water.
As of August 1, 2026, its federal record holds 2 entries in 1976, all of which EPA lists as closed. Nothing has been added since 1976.
All 2 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 the Radionuclides and Revised Rad Rule.

What is a Consumer Confidence Report?

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.
