Rural groundwater throughout NC is unmonitored, so its up to you to protect yourself with testing and information. You can explore risks to your well-sourced water in three steps using the maps below.

Step 1. Find your well. You can do this three ways:

  • Click the eye icon for “Well Locations” and use the pan and zoom tools to find your well
  • Use the Search Bar to find your address, or search  by the well owners name
  • Using your pointer, click on a well location to view a pop up of well data

Step 2. In the map sidebar, click the eye icon to view maps of each contaminant tracked: Lead, Arsenic and Coliform bacteria.

  •  Each map is represented in three colors representing  the level of estimated impurities, with guidance where available. 

Step 3. Record you findings using the checkboxes on the back of your mailer, or make your own checklist.

The legend for each map varies due to the varying EPA and NC DHHS standards. Annual bacteria testing is encouraged, and Inorganic testing is recommended every three years. For more information on well water quality, please refer to the EPA’s National Primary Drinking Water Regulations, Secondary Drinking Water Standards, and NC DHHS’ Private Wells fact sheets.
