Is MCNULTY WATER PUD required to publish a Consumer Confidence Report?

Yes. MCNULTY WATER PUD 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 MCNULTY WATER PUD’s next Consumer Confidence Report due?

MCNULTY WATER PUD’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.

MCNULTY WATER PUD Water System

Consumer Confidence Report status

MCNULTY WATER PUD 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 no open violations for MCNULTY WATER PUD.

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

System facts

System ID (PWSID): OR4100725
System type: Community Water System
Population served: 2,500
Service connections: 949
Ownership: privately owned
Water source: groundwater (wells)

MCNULTY WATER PUD is one of 203 community water systems in Oregon in the 501 to 3,300 people size category, serving 2,500 people from groundwater.

As of August 1, 2026, its federal record holds 119 entries between 1991 and 2025, all of which EPA lists as closed.

Of the 119, 106 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, inorganic chemicals, and the Total Coliform Rules.

When is MCNULTY WATER PUD’s next Consumer Confidence Report due?: MCNULTY WATER PUD’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does MCNULTY WATER PUD have any open drinking water violations on record?: As of August 1, 2026, EPA's federal records show no open violations for MCNULTY WATER PUD.
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.
