Boil Water Orders

NHDES may issue a boil water advisory to a water system in order to protect public health. The notice generally advises that all water that is used for consumption should be brought to and kept at a vigorous boil for not less than two minutes. Such advisories may be issued for the following reasons:

  • Detection of E. coli bacteria
  • Lapse in distribution system integrity
  • Failure of treatment process
  • Suspicion of other water-borne pathogens

For Additional Information

Please contact the Drinking Water and Groundwater Bureau at (603) 271-2513.
