The short answer

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

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2005 to 2024.

Nitrate, arsenic, chromium (total) and fluoride: Washington’s own results, samples taken from Jan. 7, 2020 to May 5, 2026.

Haloacetic acids (HAA5): EPA’s compliance monitoring file, samples taken from July 24, 2014 to Oct. 16, 2018. Newer results are in the utility’s annual water quality report.

Above the health goal1

Lead

Comes from pipes, often your own

Above the health goal

2.5ppb

90th percentile, 2022 to 2024

In the latest period, 9 in 10 homes sampled were at or below 2.5 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

Nitrate

Comes from the source

Below EPA’s limits

0.35ppm

Highest sample; found in 2 of 8

2026: not found

The highest sample, in 2022, was 0.35 ppm, below EPA’s legal limit of 10 ppm. In 2026, the latest year on file, it wasn’t found in its one sample.

What handles it

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

Haloacetic acids (HAA5)

Below EPA’s limits

1.7ppb

Highest yearly average, 2014 to 2018

2018: not found

Averaged by year, the highest was 1.7 ppb, in 2014, below EPA’s legal limit of 60 ppb. In 2018, the latest year on file, it wasn’t found in its one sample.

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, 42 mg/L (2.5 grains per gallon), at its one sampling point, in 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.

Violations since 2016

No health-based violations on file with EPA since 2016. There are 4 monitoring or reporting violations: a sample missed, late or not reported.

What this report can’t tell you

  • Everything else. Nitrate, arsenic, chromium (total) and fluoride results here are Washington’s own from 2020 on, with EPA’s national file for 2012 to 2019. Haloacetic acids (HAA5) comes from EPA’s file alone, which ends in 2019. Neilton Meadowland WD 8 A’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. 7, 2020 to May 5, 2026; EPA’s compliance samples are from July 24, 2014 to Oct. 16, 2018.

Testing your own tap

Neilton Meadowland WD 8 A’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 Neilton Meadowland WD 8 A serves on the state’s list. Some take samples by mail; the state’s page lists them all.
