The short answer
Nothing in EPA’s and Washington’s records for this utility is above a health goal. That covers nitrate, arsenic and other regulated chemicals, plus lead and copper, not everything. No health-based violations on file since 2016.
What was found
Nitrate: Washington’s own results, samples taken from Aug. 30, 2021 to Oct. 24, 2025, with EPA’s 2012 to 2019 file for earlier years.
Fluoride, chromium (total) and arsenic: EPA’s compliance monitoring file, samples taken from June 19, 2013 to Aug. 8, 2019. Newer results are in the utility’s annual water quality report.

What this report can’t tell you
Everything else. Nitrate results here are Washington’s own from 2021 on, with EPA’s national file for 2012 to 2019. Fluoride, chromium (total) and arsenic come from EPA’s file alone, which ends in 2019. Spokane Hutterian Brethren’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.
