SHELDON MOBILE HOME PARK Water System

Inactive system

This water system is marked inactive in EPA’s federal records as of December 1, 1997. It is no longer an operating public water system under this PWSID, and no compliance deadlines — including the 2027 Consumer Confidence Report rule — apply to it.

If you are a resident looking for your current water provider, see water systems in Brookings County, SD.

Data sourced from the EPA ECHO database (SDWA bulk download), last refreshed August 1, 2026.

System facts

System ID (PWSID): SD4607007
System type: Community Water System
Population served: 50
Service connections: 22
Ownership: privately owned
Water source: groundwater (wells)

SHELDON MOBILE HOME PARK is one of 583 community water systems in South Dakota in the 500 or fewer people size category, formerly serving 50 people from groundwater.

EPA's federal records list this system as inactive in 1997; the record below is historical.

As of August 1, 2026, its federal record holds 76 entries between 1976 and 1997, all of which EPA lists as closed. Nothing has been added since 1997.

Of the 76, 73 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, synthetic organic chemicals, and the Radionuclides and Revised Rad Rule.
