Having your own water supply can be a very nice thing. You don’t have to worry about what is put in the municipal water system, any issues that could cause water to be shut off for people connected to the municipal system won’t affect you, but it is important that you are aware of your own water source and that you keep it running and protected.
You should avoid parking vehicles near where your well is located since chemicals could leak into the ground and contaminate your water.
To make sure that your water is high quality and stays that way, you should send in samples to a lab regularly to ensure that nothing has changed. While you usually will need to use less chemicals to treat your water than what is used in a municipal system, some treatment is usually necessary to remove anything that could be harmful to your health.
