Properly constructed wells have an average lifespan of approximately 40 years, depending on use. Although properly constructed wells require little maintenance, there are a few things that you can do to ensure the health and safety of your well.
• Have the water tested by a certified laboratory regularly and keep records. The Minnesota Department of Health has a listing of certified laboratories at www.health.state.mn.us/divs/eh/wells.
• Make sure that the cap of the well is securely fastened. If the well cover becomes unfastened, have the water tested for coliform bacteria and nitrates.
• Make sure that the cap of the well is clearly marked to prevent cars or snowplows from hitting it.
• Make sure that surface water runs away from the cap of the well to prevent pooling.
• Keep hazardous products, such as paint, pesticides and motor oil, away from your well.
• If you suspect that you have an old or faulty well, have a well contractor analyze the well to decide what remedies are needed. The Minnesota Department of Health maintains a listing of certified well contractors on their website.
