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

Step 1. Find your well;

Step 2. Click the eye icon to view maps of each contaminant monitored; and

Step 3. Use the legend to understand risks (if any) and recommended testing.

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.

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 monitored: lead, arsenic and Coliform bacteria. 

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

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