Is ROCK CREEK WATER DISTRICT required to publish a Consumer Confidence Report?

Yes. ROCK CREEK WATER DISTRICT 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 ROCK CREEK WATER DISTRICT’s next Consumer Confidence Report due?

ROCK CREEK WATER DISTRICT’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.

ROCK CREEK WATER DISTRICT Water System

Consumer Confidence Report status

ROCK CREEK WATER DISTRICT 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 5 items for ROCK CREEK WATER DISTRICT 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 Oregon’s official records. Always confirm current status with Oregon before making decisions based on this information.

System facts

System ID (PWSID): OR4100337
System type: Community Water System
Population served: 300
Service connections: 108
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

ROCK CREEK WATER DISTRICT is one of 1,168 community water systems in Oregon in the 500 or fewer people size category, serving 300 people from surface water.

As of August 1, 2026, its federal record holds 125 entries between 1976 and 2025, of which 5 remain open; none are health-based.

Of the 125, 114 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 Surface Water Treatment Rules, volatile organic chemicals, and inorganic chemicals.

Common questions

Is ROCK CREEK WATER DISTRICT required to publish a Consumer Confidence Report?: Yes. ROCK CREEK WATER DISTRICT 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 ROCK CREEK WATER DISTRICT’s next Consumer Confidence Report due?: ROCK CREEK WATER DISTRICT’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does ROCK CREEK WATER DISTRICT have any open drinking water violations on record?: As of August 1, 2026, EPA's federal records show 5 items for ROCK CREEK WATER DISTRICT 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.
