MVD’s water quality and sampling is regulated by the New Hampshire Department of Environmental Services (NHDES). In order to ensure that tap water is safe to drink the United States Environmental Protection Agency (EPA) prescribes regulations which limit the amount of certain contaminants in water provided by public water systems.
To comply with the required regulations, MVD tests for various contaminants, including inorganic contaminants (salts, metals), organic chemical contaminants (synthetic and volatile chemicals), and radioactive contaminants as well as some additional unregulated contaminants/chemicals. Water analyses and treatments are performed as required and directed by the EPA’s Safe Drinking Water Act (SDWA) and the NHDES Drinking Water and Groundwater Bureau (DWGB).
All water tests are performed by an independent laboratory that is accredited in accordance with the National Environmental Laboratory Accreditation Program (NELAP) & the New Hampshire Environmental Laboratory Accreditation Program (NHELAP).
All testing is reported to and monitored by the NHDES. Results from these tests are provided on MVD’s Annual
