The ZIP code it serves
The short answer
1 result is above EPA’s legal limit, and 1 more is above the health goal. The worst: Arsenic, above the legal limit. 33 health-based violations since 2016.
What handles itWhat was found
Lead and copper: EPA SDWIS monitoring periods ending 2003 to 2023.
Arsenic, total trihalomethanes (TTHM), haloacetic acids (HAA5), nitrate and uranium: 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 and chromium (total): EPA’s compliance monitoring file, samples taken from Nov. 21, 2018 to Nov. 21, 2018. Newer results are in the utility’s annual water quality report.
Above the legal limit1
Arsenic
Comes from the source
17.8ppb
Highest yearly average, 2020 to 2023
2023 average: 5.9 ppb
Averaged by year, the highest was 17.8 ppb, in 2022, above EPA’s legal limit of 10 ppb. In 2023, the latest year on file, it averaged 5.9 ppb. EPA recorded violations for arsenic at this utility in 2022, 2023, 2025 and 2026. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 9.3 ppb, in 2015, and EPA recorded violations in 2012, 2015 and 2016.

Above the health goal1
Lead
Comes from pipes, often your own
3.5ppb
90th percentile, 2021 to 2023
In the latest period, 9 in 10 homes sampled were at or below 3.5 ppb, below EPA’s action level of 15 ppb. The action level drops to 10 ppb on Nov. 1, 2027. EPA’s health goal for lead is zero.

Fluoride
Forms or is added in treatment
1.5ppm
Highest yearly average, 2018
Averaged by year, the highest was 1.5 ppm, in 2018, below EPA’s legal limit of 4.0 ppm. That is the only year on file.

10.7ppb
Highest yearly average, 2020 to 2023
Averaged by year, the highest was 10.7 ppb, in 2023, below EPA’s legal limit of 80 ppb. That was also the latest year on file.

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.”
- NSF/ANSI 53
Claims: Arsenic (Pentavalent)<=50 ppb Reduction, Lead Reduction
For: Arsenic, Lead
Other certifiers’ wording: Arsenic (III) (50 ppb influent level)
- NSF/ANSI 58
Claims: Arsenic (Pentavalent)<=50 ppb Reduction, Lead Reduction
For: Arsenic, Lead
Other certifiers’ wording: Arsenic (Pentavalent)<=300 ppb Reduction; Arsenic (V) (300 ppb influent level)
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. Arsenic, total trihalomethanes (TTHM), haloacetic acids (HAA5), nitrate and uranium results here are Oregon’s yearly averages as CDC publishes them, from 2020 on, with EPA’s national file for 2012 to 2019. Fluoride and chromium (total) come from EPA’s file alone, which ends in 2019. McKee Bridge Mobile Home Park’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 Nov. 21, 2018 to Nov. 21, 2018.
