MVD’s water quality and sampling requirements are regulated by the New Hampshire Department of Environmental Services (NHDES) as well as the United States Environmental Protection Agency (EPA). In order to ensure that tap water is safe to drink, the EPA prescribes regulations that limit the quantity 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. In addition to routine sampling, MVD also complies with the EPA's Unregulated Contaminant Monitoring Rule (UCMR) Program, which requires public water systems to test for priority contaminants that may be present in drinking water but do not yet have established health-based standards. 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 Water Quality Report.
