Is HOLLIS required to publish a Consumer Confidence Report?

Yes. HOLLIS 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 HOLLIS’s next Consumer Confidence Report due?

HOLLIS’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.

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.

Consumer Confidence Report status

System facts

System ID (PWSID): OK2002901
System type: Community Water System
Population served: 2,264
Service connections: 957
Ownership: local government
Water source: groundwater (wells)

HOLLIS is one of 511 community water systems in Oklahoma in the 501 to 3,300 people size category, serving 2,264 people from groundwater.

As of August 1, 2026, its federal record holds 64 entries between 1994 and 2022, all of which EPA lists as closed. Nothing has been added since 2022.

Of the 64, 6 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 inorganic chemicals, the Total Coliform Rules, and the Stage 1 Disinfectants and Disinfection Byproducts Rule.

Common questions

Is HOLLIS required to publish a Consumer Confidence Report?: Yes. HOLLIS 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 HOLLIS’s next Consumer Confidence Report due?: HOLLIS’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does HOLLIS have any open drinking water violations on record?: As of August 1, 2026, EPA's federal records show no open violations for HOLLIS.
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.
