How can I be sure that my water is safe?

Ground water is for the most part very safe and dependable.  If there is cause for concern, it is best to have the water tested.  Water testing is always available to you from your local and state environmental health department.  The most common test is for Coliform bacteria, but there are a few other things that you may wish to test for like fluoride or nitrates.  Most people will not find a problem with their water, but testing will bring you peace of mind.  There are also certified private labs in most areas.
