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.

DEER ISLAND WATERWORKS Water System

Consumer Confidence Report status

DEER ISLAND WATERWORKS 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 12 items for DEER ISLAND WATERWORKS 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): OR4101233
System type: Community Water System
Population served: 90
Service connections: 33
Ownership: privately owned
Water source: groundwater (wells)

DEER ISLAND WATERWORKS is one of 1,168 community water systems in Oregon in the 500 or fewer people size category, serving 90 people from groundwater.

As of August 1, 2026, its federal record holds 140 entries between 1994 and 2026, of which 12 remain open; none are health-based.

Of the 140, 123 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 Lead and Copper Rule, synthetic organic chemicals, and volatile organic chemicals.

Common questions

Is DEER ISLAND WATERWORKS required to publish a Consumer Confidence Report?: Yes. DEER ISLAND WATERWORKS 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 DEER ISLAND WATERWORKS’s next Consumer Confidence Report due?: DEER ISLAND WATERWORKS’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does DEER ISLAND WATERWORKS have any open drinking water violations on record?: As of August 1, 2026, EPA's federal records show 12 items for DEER ISLAND WATERWORKS 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.
