The short answer

1 result is above EPA’s legal limit. The worst: Lead, above the action level. No health-based violations on file since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 1996 to 2024.

Total trihalomethanes (TTHM), haloacetic acids (HAA5) and nitrate: Oregon’s yearly averages per water system, as CDC’s Environmental Public Health Tracking Network publishes them, 2020 to 2023, with EPA’s 2012 to 2019 file for earlier years.

Fluoride, arsenic, chromium (total) and uranium: EPA’s compliance monitoring file, samples taken from July 11, 2012 to May 22, 2019. Newer results are in the utility’s annual water quality report.

Above the legal limit1

Lead

Comes from pipes, often your own

Above the action level

15.3ppb

90th percentile, 2022 to 2024

In the latest period, 9 in 10 homes sampled were at or below 15.3 ppb, above EPA’s action level of 15 ppb. The action level drops to 10 ppb on Nov. 1, 2027, and this result is at or above that. EPA’s health goal for lead is zero.

What handles it

Below EPA’s limits2

Total trihalomethanes (TTHM)

Forms or is added in treatment

Below EPA’s limits

7.0ppb

Highest yearly average, 2022

Averaged by year, the highest was 7.0 ppb, in 2022, below EPA’s legal limit of 80 ppb. That is the only year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 1.6 ppb, in 2013.

What handles it

  • NSF/ANSI 53 look for “Trihalomethanes (TTHM) Reduction”
  • NSF/ANSI 58 look for “Trihalomethanes (TTHM) Reduction”

Fluoride

Forms or is added in treatment

Below EPA’s limits

0.11ppm

Highest yearly average, 2019

Averaged by year, the highest was 0.11 ppm, in 2019, below EPA’s legal limit of 4.0 ppm. That is the only year on file.

What handles it

5 compounds tested and not foundBelow the reporting level in every sample. Not found is not the same as zero.

  • Nitrate
  • Uranium

What handles it

A certification covers specific claims, not a whole standard. Look for these claims on the certifier’s listing, not the box. Wording varies a little: NSF writes “Lead Reduction,” WQA just “Lead.”

At the tap, or for the whole house?

Lead and copper usually come from pipes and fixtures inside or near your home. A whole-house system sits where water enters, so it cannot catch what your own plumbing adds after it. For those, the filter that counts is the one at the tap. How whole-house systems compare.

What this report can’t tell you

  • Everything else. Total trihalomethanes (TTHM), haloacetic acids (HAA5) and nitrate results here are Oregon’s yearly averages as CDC publishes them, from 2020 on, with EPA’s national file for 2012 to 2019. Fluoride, arsenic, chromium (total) and uranium come from EPA’s file alone, which ends in 2019. Kozy Acres Water System’s own annual report, which it must send you every year, has newer results for those and the contaminants this page does not show.

  • Your own plumbing. Lead results are the 90th percentile across homes the utility samples. Your home’s service line, solder and fixtures decide yours. A certified lab test is the only way to know.

  • What it means for your health. This page reports what the records show and EPA’s limits and goals; it is not medical advice. If you are worried about a health effect, talk to a doctor or your local health department.

  • Anything after the latest data. SDWIS data is from 2026 Q3; UCMR 5 didn’t sample this utility; CDC’s yearly averages for Oregon cover 2020 to 2023; EPA’s compliance samples are from July 11, 2012 to May 22, 2019.

Testing your own tap

Kozy Acres Water System’s results are for the water it sends out. What your own service line, solder and fixtures add shows up only in a test of your tap, by a lab Oregon certifies.

No lab Oregon certifies is within 75 miles of the area Kozy Acres Water System serves on the state’s list. Some take samples by mail; the state’s page lists them all.
