Help Celebrate National Protect Your Groundwater Day by Protecting New Hampshire’s Main Source of Drinking Water

Concord, NH - The New Hampshire Department of Environmental Services wants New Hampshire residents to join the Department in celebrating National Protect Your Groundwater Day. In New Hampshire, groundwater serves as the main source of drinking water for 60 percent of the state’s population, or 800,000 residents. Residents and businesses use 94 million gallons of groundwater per day. Protecting this resource is important and involves preventing contamination and using water efficiently. Contaminants include hazardous substances found in a variety of household products, such as pesticides, paint thinners, and most petroleum-based products. Once in groundwater, contaminants often require expensive and complex treatment to remove them.

Preventing contamination and implementing water conservation measures together are a foundation for a cleaner and more sustainable resource. New Hampshire residents can do this by adopting some simple measures to protect and conserve groundwater.

1. Prevent groundwater contamination

  • Hazardous substances are in many household products. Read the labels to determine whether the contents are hazardous or contact the manufacturer for more information.
  • Store, transfer and use them properly and ensure they are not spilled, flushed or otherwise released to the ground.
  • Dispose of hazardous substances safely through a local household hazardous waste collection or at your local recycling/transfer station.
  • Make sure your home heating oil tank and connections to oil burners are regularly inspected for rust or leaks.

2. Protect your well and test your water

  • Check the area around your private well to keep it free from contaminants
  • Is there an abandoned well on your property? If so, properly decommission the abandoned well to keep from becoming a route for contaminants at the surface to reach groundwater.
  • DES recommends regular testing of residential wells for certain natural and man-made containments.

3. Conserve water at home

  • Figure out where you and your family use the most water and find ways to use it more efficiently. You will be saving money while you protect groundwater. To find out more about water conservation tips and practices, visit DES’s water conservation program website ( and look under “A to Z List”).
