The short answer

2 results are above EPA’s legal limit, and 1 more is above the health goal. The worst: Haloacetic acids (HAA5), above the legal limit. 60 health-based violations since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2003 to 2025.

Haloacetic acids (HAA5), total trihalomethanes (TTHM), fluoride, arsenic, chromium (total) and nitrate: Washington’s own results, samples taken from March 16, 2020 to Aug. 20, 2026, with EPA’s 2012 to 2019 file for earlier years.

164ppb

Highest yearly average, 2020 to 2026

2026 average: 98.5 ppb

Averaged by year, the highest was 164 ppb, in 2022, about 2.7 times EPA’s legal limit of 60 ppb. Its highest single sample was 267 ppb. In 2026, the latest year on file, its three samples averaged 98.5 ppb, above the limit. EPA recorded violations for haloacetic acids (HAA5) at this utility in 2024, 2025 and 2026. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 196 ppb, in 2015, and EPA recorded a violation in 2018.

Above the health goal

5.0ppb

90th percentile, 2023 to 2025

In the latest period, 9 in 10 homes sampled were at or below 5.0 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.

0.027ppm

Highest yearly average, 2021 to 2022

Averaged by year, the highest was 0.027 ppm, in 2022, below EPA’s legal limit of 4.0 ppm. Its highest single sample was 0.11 ppm. 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: Trihalomethanes (TTHM) Reduction, Lead Reduction

    For: Total trihalomethanes (TTHM), Lead

    Other certifiers’ wording: VOC Reduction

  • NSF/ANSI 58

    Claims: Trihalomethanes (TTHM) Reduction, Lead Reduction

    For: Total trihalomethanes (TTHM), 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.

Hardness

Moderately hard, 77 mg/L (4.5 grains per gallon), at its one sampling point, in 2020.

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.

What this report can’t tell you

  • Everything else. Haloacetic acids (HAA5), total trihalomethanes (TTHM), fluoride, arsenic, chromium (total) and nitrate results here are Washington’s own from 2020 on, with EPA’s national file for 2012 to 2019. Orient Water Company’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 March 16, 2020 to Aug. 20, 2026.

Testing your own tap

Orient Water Company’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.

The lab Washington certifies closest to the area Orient Water Company serves, in a straight line. Call first: certification is test by test, and not every lab takes samples from homeowners.
