Purchased surface water means the system buys surface water from another public water system rather than drawing its own. 299 Oklahoma systems (24%) list purchased surface water as their primary source.

Does Ratliff City have drinking water violations?
Of the 12 most recent violations in EPA's records, 10 are health-based, and the most recent began in July 2023. The violations listed here began between May 1999 and July 2023. By type: 10 contaminant level above the legal limit and 2 monitoring and reporting. The contaminant or rule involved most often is Total trihalomethanes (TTHM) (9 of them). EPA lists 11 as resolved and 1 as archived. Resolved means at least one resolving action is on record: the system returned to compliance, the rule no longer applies, or no further action was needed. Archived means the violation was not marked resolved but is more than five years past the end of the noncompliance period, so it no longer counts toward current compliance status.
