Wake County encourages all private well users to have their water tested regularly to ensure that it is safe for drinking. Wake County Environmental Services is pleased to offer private well users a wide range of drinking water testing services to help them ensure their water is safe.

If you have never had your well water tested, or it has been more than five years since your last test, Wake County recommends the “first-timer’s package,” which includes testing for Coliform Bacteria, Inorganics, Volatile Organic Compounds, Pesticides and Herbicides. The total cost of this package, including the trip fee, is $275. Discounted fees are available for lower-income residents.

If you live in the eastern third of the county, or if your indoor air has been found to have greater than 4 pCi/L of radon (before mitigation), Wake County also recommends Gross Alpha testing for radiological contaminants.

To schedule your well tests, or if you have questions about which tests you need, call Wake County Environmental Services at 919-856-7400 and select option 8 to speak to someone in customer service.

The following tables list prices and recommendations for common individual well water tests. Discounted well testing fees are available for lower-income residents. Ask for more information when you call to schedule your tests.

Tests for overall levels of alpha particle radiation from uranium, radium 226 or radium 228.
