Well water testing: frequently asked questions
- What should I test my well water for?
- At minimum, test private well water for total coliform bacteria and E. coli every year, plus nitrate if you live near farmland or have an infant in the home. A broader Level 1 or Level 2 panel adds the metals, minerals, and chemistry that affect both safety and plumbing. If you are not sure, the Annual Well Safety Check covers the common essentials in one kit.
- How often should I test my private well?
- Most state health departments recommend testing a private well at least once a year for bacteria and nitrate, and any time after flooding, well repairs, a noticeable change in taste, color, or odor, or before buying or selling a home.
- How does at-home well water testing work?
- Order a kit and it ships to your door. You collect a sample at your tap or wellhead in a few minutes, then mail it back in the prepaid package to the certified lab. You receive an easy-to-read report explaining what was found, how it compares to drinking-water guidelines, and what to do next.
- Are these water tests done by a certified lab?
- Yes. Samples are analyzed by SimpleLab and its Tap Score certified laboratory network. DrillerDB helps you choose the right test for your well; the certified lab performs the analysis and reporting.
- Which water test kit should I choose?
- If you have never tested, or it has been more than a year, start with the Annual Well Safety Check. Choose the Basic Bacteria Check for a quick safety screen, the Nitrate Check if you are near agriculture or have an infant, or the New Well / Real Estate Baseline for a comprehensive record on a new well or a home sale.
