The short answer

1 result is above the limit’s level with no violation recorded, and 1 more is above the health goal. The worst: Arsenic, above the limit’s level, no violation. No health-based violations on file since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2002 to 2022.

Arsenic, fluoride, nitrate, haloacetic acids (HAA5) and total trihalomethanes (TTHM): Washington’s own results, samples taken from Jan. 17, 2020 to Aug. 12, 2026, with EPA’s 2012 to 2019 file for earlier years.

Chromium (total): EPA’s compliance monitoring file, samples taken from Aug. 9, 2012 to Dec. 23, 2019. Newer results are in the utility’s annual water quality report.

Above the limit’s level, no violation recorded1

Arsenic

Comes from the source

Above the limit’s level, no violation

21.7ppb

Highest yearly average, 2020 to 2026

2026, one sample: 1.1 ppb

Averaged by year, the highest was 21.7 ppb, in 2024, about twice EPA’s legal limit of 10 ppb. Its highest single sample was 31.9 ppb. In 2026, the latest year on file, its one sample was 1.1 ppb. EPA judges this limit on running averages at each sampling point, and recorded no violation for arsenic at this utility since 2020. Results like these with no violation often include water sampled before treatment or blending; the utility’s annual report says what reaches the tap. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 22.5 ppb, in 2012.

Above the health goal1

Lead

Comes from pipes, often your own

Above the health goal

1.0ppb

90th percentile, 2022

In the latest period, 9 in 10 homes sampled were at or below 1.0 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.

What handles it

Below EPA’s limits2

Fluoride

Forms or is added in treatment

Below EPA’s limits

0.18ppm

Highest yearly average, 2023

Averaged by year, the highest was 0.18 ppm, in 2023, 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 2019.

What handles it

Nitrate

Comes from the source

Below EPA’s limits

0.1ppm

Highest sample; found in 1 of 3

2023 average: 0.05 ppm

The highest sample, in 2023, was 0.1 ppm, below EPA’s legal limit of 10 ppm. That was also the latest year on file, and its two samples averaged 0.05 ppm.

What handles it

  • NSF/ANSI 58 look for “Nitrate/Nitrite Reduction”
  • NSF/ANSI 53 look for “Nitrate/Nitrite (30 ppm challenge)”
3 compounds tested and not foundBelow the reporting level in every sample. Not found is not the same as zero.

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.

Violations since 2016

No health-based violations on file with EPA since 2016. There are 39 monitoring or reporting violations: a sample missed, late or not reported.

What this report can’t tell you

  • Everything else. Arsenic, fluoride, nitrate, haloacetic acids (HAA5) and total trihalomethanes (TTHM) results here are Washington’s own from 2020 on, with EPA’s national file for 2012 to 2019. Chromium (total) comes from EPA’s file alone, which ends in 2019. Hunters Water District’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 Jan. 17, 2020 to Aug. 12, 2026; EPA’s compliance samples are from Aug. 9, 2012 to Dec. 23, 2019.

Testing your own tap

Hunters Water District’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.
