Water Quality Testing for Private (Domestic) Wells: NHDES recommends residents test their well water for all contaminants commonly found in New Hampshire's groundwater.

Private well owners are encouraged to test their water wells every three to five years for the complete set of contaminants referred to as the "Standard Analysis" Adobe Acrobat Reader Symbol. Contact an accredited laboratory to confirm the lab's capacity to complete all recommended tests and for pricing. It is not necessary to do all of these tests at one time.

NHDES Be Well Informed Private Well App – is an interactive web application for private well owners to interpret water quality test results and identify appropriate water treatment options.
