The short answer

1 result is above EPA’s legal limit. The worst: Lead, above the action level. 1 health-based violation since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2005 to 2015.

Copper: EPA’s file records a utility’s copper only when it exceeds the action level. The last here was 5.1 ppm, for the period ending June 30, 1998. None since is on file, so it is not counted as a current finding.

Nitrate, total trihalomethanes (TTHM), arsenic, chromium (total), fluoride and haloacetic acids (HAA5): Washington’s own results, samples taken from July 1, 2020 to Aug. 19, 2026, with EPA’s 2012 to 2019 file for earlier years.

Above the legal limit1

Lead

Comes from pipes, often your own

Above the action level

274ppb

90th percentile, 2015

In the latest period, 9 in 10 homes sampled were at or below 274 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

Below EPA’s limits2

Nitrate

Comes from the source

Below EPA’s limits

4.5ppm

Highest sample; found in 15 of 15

2026, one sample: 4.1 ppm

The highest sample, in 2021, was 4.5 ppm, below EPA’s legal limit of 10 ppm. In 2026, the latest year on file, its one sample was 4.1 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 4.3 ppm, in 2016.

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

Total trihalomethanes (TTHM)

Forms or is added in treatment

Below EPA’s limits

0.81ppb

Highest yearly average, 2020 to 2023

2023, one sample: 0.61 ppb

Averaged by year, the highest was 0.81 ppb, in 2020, below EPA’s legal limit of 80 ppb. In 2023, the latest year on file, its one sample was 0.61 ppb.

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.”

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

Soft, typically 50 mg/L (2.9 grains per gallon), across 2 sampling points, 2021 to 2022.

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. Nitrate, total trihalomethanes (TTHM), arsenic, chromium (total), fluoride and haloacetic acids (HAA5) results here are Washington’s own from 2020 on, with EPA’s national file for 2012 to 2019. Kelley Crest’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 July 1, 2020 to Aug. 19, 2026.

Testing your own tap

Kelley Crest’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.

No lab Washington certifies is within 75 miles of the area Kelley Crest serves on the state’s list. Some take samples by mail; the state’s page lists them all.
