How do I get my well water tested? How often should I test my well water?

Be sure to use a N.H. accredited laboratory for private water testing and interpretation. You can call the Health Department for a current list of N.H. accredited private and municipal laboratories. If you are taking the samples yourself, complimentary bottles are available at the Health Department. The N.H. Department of Environmental Services (NHDES) recommends a standard analysis every 3-5 years. This analysis covers the most common contaminants such as bacteria, arsenic, iron, manganese. Additional tests are available for radon and VOC’s. Private well owners can utilize the interactive web application from NH DES, "Be Well Informed" to evaluate their well testing results and treatment guidance.
