The short answer

2 results are above EPA’s legal limit. The worst: Lead, above the action level. 13 health-based violations since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2003 to 2022.

Copper: EPA’s file records a utility’s copper only when it exceeds the action level. The last here was 2.3 ppm, for the period ending Dec. 31, 2005. None since is on file, so it is not counted as a current finding.

Arsenic, total trihalomethanes (TTHM), nitrate, haloacetic acids (HAA5), fluoride and chromium (total): Washington’s own results, samples taken from Jan. 30, 2020 to Sept. 8, 2026, with EPA’s 2012 to 2019 file for earlier years.

Above the legal limit2

Lead

Comes from pipes, often your own

Above the action level

19.5ppb

90th percentile, 2020 to 2022

In the latest period, 9 in 10 homes sampled were at or below 19.5 ppb, above EPA’s action level of 15 ppb. The action level drops to 10 ppb on Nov. 1, 2027, and this result is at or above that. EPA’s health goal for lead is zero.

What handles it

Arsenic

Comes from the source

Above the legal limit

11.9ppb

Highest yearly average, 2020 to 2026

2026 average: 5.5 ppb

Averaged by year, the highest was 11.9 ppb, in 2023, above EPA’s legal limit of 10 ppb. Its highest single sample was 12.8 ppb. In 2026, the latest year on file, its 16 samples averaged 5.5 ppb. EPA recorded violations for arsenic at this utility in 2020, 2021, 2023 and 2024. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 9.8 ppb, in 2017, and EPA recorded violations in 2018 and 2019.

0.25ppm

Highest yearly average, 2025

Averaged by year, the highest was 0.25 ppm, in 2025, below EPA’s legal limit of 4.0 ppm. That is the only 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: Lead Reduction, Arsenic (Pentavalent)<=50 ppb Reduction

    For: Lead, Arsenic

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

  • NSF/ANSI 58

    Claims: Lead Reduction, Arsenic (Pentavalent)<=50 ppb Reduction

    For: Lead, Arsenic

    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.

Hardness

Very hard, typically 207 mg/L (12.1 grains per gallon), across 2 sampling points, in 2025.

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. Arsenic, total trihalomethanes (TTHM), nitrate, haloacetic acids (HAA5), fluoride and chromium (total) results here are Washington’s own from 2020 on, with EPA’s national file for 2012 to 2019. Bonnie View Water’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. 30, 2020 to Sept. 8, 2026.

Testing your own tap

Bonnie View Water’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.
