The short answer

1 result is above EPA’s legal limit, and 1 more is above the health goal. The worst: Nitrate, above the legal limit. 10 health-based violations since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2013 to 2024.

Nitrate, arsenic 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.

Haloacetic acids (HAA5), total trihalomethanes (TTHM), fluoride and chromium (total): EPA’s compliance monitoring file, samples taken from Sept. 7, 2012 to Oct. 5, 2018. Newer results are in the utility’s annual water quality report.

Above the legal limit1

Nitrate

Comes from the source

Above the legal limit

1.1ppm

Highest yearly average, 2020 to 2023

2023: not found

Averaged by year, the highest was 1.1 ppm, in 2021, below EPA’s legal limit of 10 ppm. In 2023, the latest year on file, it wasn’t found. EPA judges this limit at each sampling point, and recorded a violation for nitrate at this utility in 2020. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 13.3 ppm, in 2017, and EPA recorded violations in 2017 and 2019.

Lead

Above the health goal

0.28ppb

90th percentile, 2022 to 2024

In the latest period, 9 in 10 homes sampled were at or below 0.28 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.

0.83ppm

Highest yearly average, 2015 to 2018

Averaged by year, the highest was 0.83 ppm, in 2018, below EPA’s legal limit of 4.0 ppm. That was also the latest year on file.

What handles it

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: Nitrate/Nitrite (30 ppm challenge), Lead Reduction

    For: Nitrate, Lead

  • NSF/ANSI 58

    Claims: Nitrate/Nitrite Reduction, Lead Reduction

    For: Nitrate, Lead

    Other certifiers’ wording: Nitrate

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. Nitrate, arsenic 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. Haloacetic acids (HAA5), total trihalomethanes (TTHM), fluoride and chromium (total) come from EPA’s file alone, which ends in 2019. Pinewood Mobile Manor’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 Sept. 7, 2012 to Oct. 5, 2018.

Testing your own tap

Pinewood Mobile Manor’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.
