MCCUDDYS LANDING Water System

Consumer Confidence Report status

MCCUDDYS LANDING 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 4 items for MCCUDDYS LANDING 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.

MCCUDDYS LANDING is one of 1,168 community water systems in Oregon in the 500 or fewer people size category, serving 70 people from groundwater.

As of August 1, 2026, its federal record holds 94 entries between 2002 and 2026, of which 4 remain open; none are health-based.

Of the 94, 90 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 Lead and Copper Rule.

Common questions

Is MCCUDDYS LANDING required to publish a Consumer Confidence Report?

Yes. MCCUDDYS LANDING 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 MCCUDDYS LANDING’s next Consumer Confidence Report due?

MCCUDDYS LANDING’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.

Does MCCUDDYS LANDING have any open drinking water violations on record?

As of August 1, 2026, EPA's federal records show 4 items for MCCUDDYS LANDING 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.
