Is MARBLE WC required to publish a Consumer Confidence Report?

Yes. MARBLE WC 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 MARBLE WC’s next Consumer Confidence Report due?

MARBLE WC’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.

MARBLE WC Water System

Consumer Confidence Report status

MARBLE WC 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 1 item for MARBLE WC that is 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 Colorado’s official records. Always confirm current status with Colorado before making decisions based on this information.

System facts

System ID (PWSID): CO0226500
System type: Community Water System
Population served: 113
Service connections: 48
Ownership: privately owned
Water source: groundwater (wells)

MARBLE WC is one of 1,060 community water systems in Colorado in the 500 or fewer people size category, serving 113 people from groundwater.

As of August 1, 2026, its federal record holds 148 entries between 1996 and 2025, of which 1 remains open; none are health-based.

Of the 148, 145 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, synthetic organic chemicals, and the Total Coliform Rules.

Common questions

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