Do You Need to Test Your Drinking Water in Oregon?
Answers to the questions Oregon and Salem residents ask most about drinking water testing.
If you get your water from a private well, yes — Oregon does not regulate or monitor private wells, so testing is entirely the owner’s responsibility. Oregon Dept of Water Resources recommends testing private well water at least once a year for total coliform bacteria and nitrate, and every 2–3 years for arsenic and other contaminants common in Oregon aquifers. If you are on a public/city water system, your utility already tests the water, but you may still want to test at your own tap for lead, especially in older homes.
