Is MASON WATER DEPT required to publish a Consumer Confidence Report?

Yes. MASON WATER DEPT 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 MASON WATER DEPT’s next Consumer Confidence Report due?

MASON WATER DEPT’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.

MASON WATER DEPT Water System

Consumer Confidence Report status

MASON WATER DEPT 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 11 items for MASON WATER DEPT 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 West Virginia’s official records. Always confirm current status with West Virginia before making decisions based on this information.

System facts

System ID (PWSID): WV3302708
System type: Community Water System
Population served: 1,679
Service connections: 769
Ownership: local government
Water source: groundwater (wells)

MASON WATER DEPT is one of 335 community water systems in West Virginia in the 501 to 3,300 people size category, serving 1,679 people from groundwater.

As of August 1, 2026, its federal record holds 123 entries between 2002 and 2025, of which 11 remain open; none are health-based.

Of the 123, 96 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 synthetic organic chemicals, volatile organic chemicals, and the Public Notice Rule and Revised PN Rule.

Common questions

Is MASON WATER DEPT required to publish a Consumer Confidence Report?: Yes. MASON WATER DEPT 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 MASON WATER DEPT’s next Consumer Confidence Report due?: MASON WATER DEPT’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does MASON WATER DEPT have any open drinking water violations on record?: As of August 1, 2026, EPA's federal records show 11 items for MASON WATER DEPT 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.
