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
