CLAY RURAL WATER SYSTEM is one of 30 community water systems in South Dakota in the 3,301 to 10,000 people size category, serving 4,780 people from groundwater.

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.
