​Wake County encourages private well users living in the areas highlighted below to have their well water tested for Gross Alpha & Beta radioactivity and Radon. Wake County Environmental Services also recommends testing indoor air for radon in these areas.

You can easily order all of these tests by calling 919-856-7400 and asking for the "Rads Package." The cost of this test package is $100, plus a trip fee.

Within these two areas, naturally occurring radioactive elements are more common due to granite rock formations underground. The largest of these formations, called the Rolesville Granite, extends into neighboring Franklin and Johnston counties. A similar but smaller granite formation is also present southwest of Fuquay-Varina.

Well users in other parts of the county who have had problems with radon in their indoor air should consider having their well water tested for gross alpha radioactivity and radon.

The Rads Package is just one of many well testing services that Wake County Environmental Services offers for private well users. See Wake County’s Well Water Testing page for instructions and more information about well testing services.
