Private Well Testing Program

If you have a private well, then water quality testing should be important to you and your family. Some contaminants in drinking water have been linked to cancer and toxicity, posing a risk to human health. Many contaminants often have no taste, odor, or color. Their presence can only be determined by laboratory testing.

While there is no state requirement to have your well water tested (although there may be from your mortgage lender or town), NHDES recommends that all homeowners with private wells do so. Use the accredited laboratory search to find a laboratory near you.
