Private Well Water Safety & Testing – What You Need to Know

TESTING YOUR WELL WATER

Test your well water once a year for bacteria and nitrates and every 3 to 5 years for arsenic, fluoride, uranium, radon, lead, and manganese.
If you have never tested your well water, we recommend doing a comprehensive test. Other times to test your well include:

  • If you are expecting a baby
  • Your water changes in smell, taste, and color
  • Your well runs dry and comes back
  • When buying a new home
  • After installing a water treatment system or replacing parts of your treatment system
  • After any work is done on your well
