Monitoring & Treatment

Hampstead Area Water Company, Inc. (HAWC) is dedicated to providing our customers with safe drinking water; this is achieved through routine monitoring and treatment of the water supply.  


Water analyses and treatments are performed as required and directed by the United States Environmental Services Agency’s Safe Drinking Water Act (SDWA) and the New Hampshire Department of Environmental Services’s (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 Conference (NELAC) & the New Hampshire Environmental Laboratory Accreditation Program (NH ELAP).

Some of the contaminants we monitor for include:

  • Microbial contaminants from septic systems, agriculture & livestock operations, and wildlife.
  • Inorganic contaminants such as salts and metals that can naturally occur or result from storm water runoff, industrial & domestic waste water discharges, or farming.
  • Pesticides and herbicides from sources such as agriculture, storm water runoff, and residential uses
  • Organic chemical contaminants, including synthetic and volatile organic chemicals, which are by-products of industrial processes.
  • Radioactive contaminants that can naturally occur.

All of HAWC’s water sources originate from bedrock wells. Water from the wells is naturally filtered and is free of almost all regulated contaminants.

Water treatment includes the use of chlorine for disinfection to ensure the water is free of harmful bacteria. Fluoride is not added to your water supply.
