The short answer

1 result is above the health goal. The worst: Nitrate, above the health goal. No health-based violations on file since 2016.

What handles it

What was found

Nitrate, fluoride, arsenic and chromium (total): Washington’s own results, samples taken from Jan. 6, 2020 to Dec. 23, 2025, with EPA’s 2012 to 2019 file for earlier years.

Above the health goal1

Nitrate

Comes from the source

Above the health goal

16.3ppm

Highest sample; found in 3 of 9

2025: not found

From 2021 to 2023, two samples were above EPA’s legal limit of 10 ppm, the highest 16.3 ppm in 2021. Two have no follow-up sample on file within 30 days. 10 ppm is also EPA’s health goal. In 2025, the latest year on file, it wasn’t found in its one sample. EPA recorded no violation for nitrate at this utility since 2020. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 0.46 ppm, in 2018.

Below EPA’s limits

1.2ppm

Highest yearly average, 2021

Averaged by year, the highest was 1.2 ppm, in 2021, below EPA’s legal limit of 4.0 ppm. That is the only year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 0.15 ppm, in 2018.

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

    Claim: Nitrate/Nitrite (30 ppm challenge)

    For: Nitrate

  • NSF/ANSI 58

    Claim: Nitrate/Nitrite Reduction

    For: Nitrate

    Other certifiers’ wording: Nitrate

At the tap, or for the whole house?

These come with the water itself, so a whole-house system certified for the same claims treats every tap and shower. A filter at the tap treats drinking water for much less. How whole-house systems compare.

Hardness

Soft, 40 mg/L (2.3 grains per gallon), at its one sampling point, in 2021.

Hardness is calcium and magnesium. EPA sets no limit for it: it shows up as scale on fixtures and in water heaters, and as soap that won’t lather. USGS calls water above 60 mg/L moderately hard, above 120 hard and above 180 very hard.

Violations since 2016

No health-based violations on file with EPA since 2016. There are 32 monitoring or reporting violations: a sample missed, late or not reported.

What this report can’t tell you

  • Everything else. Nitrate, fluoride, arsenic and chromium (total) results here are Washington’s own from 2020 on, with EPA’s national file for 2012 to 2019. Marlin Hutterian’s own annual report, which it must send you every year, has 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; Washington’s results run from Jan. 6, 2020 to Dec. 23, 2025.

Testing your own tap

Marlin Hutterian’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 Washington certifies.
