If you are a private well owner, you are responsible for the quality of your drinking water and maintaining your well system. Regular water testing and well inspection are imperative in order to keep your water well operating properly and to ensure there are no contaminants so you always have a safe supply of drinking water. At a minimum, your well water should be tested every year for bacteria, the most common water quality problem. Other tests may be required or recommended, depending on where you live and what is located near your water well system.
