When should you test your well?
Have your well tested if there are known well problems in your area, if you have experienced problems near your well, if you have replaced or repaired any part of your well, or if you noticed a change in the water quality. Check your well every spring for mechanical problems and total coliform bacteria, nitrates, and pH levels.
