COOKSON HILLS CHRISTIAN SCHOOL Water System

Inactive system

This water system is marked inactive in EPA’s federal records as of July 29, 2019. 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 Adair County, OK.

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 Oklahoma’s official records. Always confirm current status with Oklahoma before making decisions based on this information.

System facts

System ID (PWSID): OK2000118
System type: Community Water System
Population served: 150
Service connections: 65
Ownership: privately owned
Water source: groundwater (wells)

COOKSON HILLS CHRISTIAN SCHOOL is one of 1,277 community water systems in Oklahoma in the 500 or fewer people size category, formerly serving 150 people from groundwater.

EPA's federal records list this system as inactive in 2019; the record below is historical.

As of August 1, 2026, its federal record holds 96 entries between 1997 and 2019, all of which EPA lists as closed. Nothing has been added since 2019.

Of the 96, 54 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, volatile organic chemicals, and the Consumer Confidence Rule.
