Maintain your well
Well owners should create a well maintenance log to keep track of the well's history, construction details, water testing results, inspections, and regular maintenance and repairs.
Well owners should inspect the wellhead several times a year to check the conditions of the well covering, casing, and cap.
The well should also be inspected every 10 years or so by a qualified well driller or pump installer.
Well owners should ensure that the water from the well is tested annually for bacteria and nitrates (at a minimum); more often if there has been a change in the taste, color, or smell of the water.
