What is a Consumer Confidence Report?

A Consumer Confidence Report (CCR) is the annual drinking water quality report that community water systems must provide to the people they serve. 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.

MAYSVILLE Water System

Consumer Confidence Report status

MAYSVILLE must publish a Consumer Confidence Report — the annual drinking water quality report covering calendar year 2026 — by July 1, 2027.

As of August 1, 2026, EPA's federal records show 2 items for MAYSVILLE that are open and awaiting resolution. None are health-based violations — open items of this kind are most often monitoring or reporting requirements, not water-safety findings.

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): OK1010807
System type: Community Water System
Population served: 1,212
Service connections: 603
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

MAYSVILLE is one of 511 community water systems in Oklahoma in the 501 to 3,300 people size category, serving 1,212 people from surface water.

As of August 1, 2026, its federal record holds 200 entries between 1999 and 2026, of which 2 remain open; none are health-based.

Of the 200, 60 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 Stage 2 Disinfectants and Disinfection Byproducts Rule, the Stage 1 Disinfectants and Disinfection Byproducts Rule, and the Surface Water Treatment Rules.

Common questions

Is MAYSVILLE required to publish a Consumer Confidence Report?: Yes. MAYSVILLE is a community water system, and federal rules (40 CFR 141 Subpart O) require every community water system to publish a Consumer Confidence Report each year.
When is MAYSVILLE’s next Consumer Confidence Report due?: MAYSVILLE’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does MAYSVILLE have any open drinking water violations on record?: As of August 1, 2026, EPA's federal records show 2 items for MAYSVILLE that are open and awaiting resolution. None are health-based violations — open items of this kind are most often monitoring or reporting requirements, not water-safety findings.
What is a Consumer Confidence Report?: A Consumer Confidence Report (CCR) is the annual drinking water quality report that community water systems must provide to the people they serve. 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.
