The short answer

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

What handles it

What was found

Nitrate: Washington’s own results, samples taken from July 26, 2021 to Aug. 17, 2026, with EPA’s 2012 to 2019 file for earlier years.

Arsenic, chromium (total), fluoride and uranium: EPA’s compliance monitoring file, samples taken from July 20, 2016 to June 21, 2018. Newer results are in the utility’s annual water quality report.

Above the health goal1

Arsenic

Comes from the source

Above the health goal

2.0ppb

Highest yearly average, 2018

Averaged by year, the highest was 2.0 ppb, in 2018: below EPA’s legal limit of 10 ppb, but above its health goal of zero. That is the only year on file.

What handles it

  • NSF/ANSI 58 look for “Arsenic (Pentavalent)<=50 ppb Reduction”
  • NSF/ANSI 53 look for “Arsenic (Pentavalent)<=50 ppb Reduction”

Below EPA’s limits2

Nitrate

Comes from the source

Below EPA’s limits

1.3ppm

Highest sample; found in 3 of 8

2026 average: 0.66 ppm

The highest sample, in 2026, was 1.3 ppm, below EPA’s legal limit of 10 ppm. That was also the latest year on file, and its two samples averaged 0.66 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 1.3 ppm, in 2016.

What handles it

  • NSF/ANSI 58 look for “Nitrate/Nitrite Reduction”
  • NSF/ANSI 53 look for “Nitrate/Nitrite (30 ppm challenge)”

Chromium (total)

Comes from the source

Below EPA’s limits

5.0ppb

Highest yearly average, 2018

Averaged by year, the highest was 5.0 ppb, in 2018, below EPA’s legal limit of 100 ppb. Its highest single sample was 10 ppb. That is the only year on file.

What handles it

3 compounds tested and not foundBelow the reporting level in every sample. Not found is not the same as zero.
  • Fluoride
  • Lead
  • 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.”

  • NSF/ANSI 53

    Claim: Arsenic (Pentavalent)<=50 ppb Reduction

    For: Arsenic

    Other certifiers’ wording: Arsenic (III) (50 ppb influent level)

  • NSF/ANSI 58

    Claim: Arsenic (Pentavalent)<=50 ppb Reduction

    For: Arsenic

    Other certifiers’ wording: Arsenic (Pentavalent)<=300 ppb Reduction; Arsenic (V) (300 ppb influent level)

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.

What this report can’t tell you

  • Everything else. Nitrate results here are Washington’s own from 2021 on, with EPA’s national file for 2012 to 2019. Arsenic, chromium (total), fluoride and uranium come from EPA’s file alone, which ends in 2019. Olympus Beach Tracts’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; Washington’s results run from July 26, 2021 to Aug. 17, 2026; EPA’s compliance samples are from July 20, 2016 to June 21, 2018.

Testing your own tap

Olympus Beach Tracts’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.
