Drinking Water in Your Home

Clean and safe drinking water is an important part of a healthy home environment. Although most drinking water in Minnesota is safe, it is possible for water to be contaminated by bacteria, nitrate, lead, arsenic or other chemicals. It is important to know the source of your water and whether it needs to be tested.

Private Water Wells

Properly constructed and maintained private water wells can provide a plentiful and safe supply of water. However, some private wells may be vulnerable to contamination, particularly if poorly constructed, damaged (e.g. lawnmower or snowplow running into the well casing), or located near a contamination source. If you have a private well, you should test it periodically to determine if your water is safe for drinking. For more information, see: Wells that are no longer in use should be properly sealed. You may contact a licensed well contractor to evaluate, repair, or seal an existing well or construct a new well. For further information:

Public Water Systems

Public water systems (such as municipal water utilities, rural water systems, and manufactured home parks) are required by law to test their water regularly and must supply safe drinking water. Testing results are available from your public water system in the form of an annual Consumer Confidence Report. For more information, see:

Lead in Water

Whether your water comes from a private well or public water system, it is recommended that you run the water for 30 to 60 seconds before using it for drinking. If water has been in contact with lead-containing plumbing materials for an extended period of time, this will help reduce lead levels by flusing it out. For more information, see:
