Private Well Water

Most of us get our drinking water from municipal water treatment plants. This water is treated to kill germs and tested to make sure that it is safe to drink.

You should regularly check your well to make sure that the cap is fitting tightly and that pipes, pumps, valves, storage tanks, meters and fittings are in good condition. Remember, it’s always best to stop a problem before it starts.

Getting Your Water Tested

If you get your water from a private well, you should have it tested at least 3 to 4 times a year. The most important time to test your well water is in the spring.

Making Sure Your Well is Secure

Wells don’t last for ever. Over time, they may become damaged or wear down. That’s why it is important to regularly check your well for structural issues. Some things to consider:

  • Is there a cap on the well and is it secure?
  • Are there cracks or damage to the well? 
  • Does the top of the well extend at least 40 cm (16 inches) above the ground?

If you notice damage to your well, contact a licensed well contractor for repairs.

It’s also important to be aware of potential sources of pollution that could cause your well water to become unsafe. Do these things to keep your well water safe:

  • Prevent water from pooling around your well
  • Keep grass around the well cut short
  • Do not plant gardens or crops near your well
  • Remove animal feces near your well
  • Keep fertilizer, paint, pesticides and motor oil away from your well
