Wake County has found wells with unsafe levels of uranium, radon and radium in the water. These substances occur naturally in the rock located underground in the areas highlighted on the map below. Drinking well water contaminated with them may cause significant health problems, including kidney toxicity and cancer.

Private well owners are responsible for the regular maintenance and testing of their water supply.

This notice is to inform residents about the naturally-occurring groundwater contaminants found in the highlighted area on the map below, so they can decide what actions to take to determine whether their wells are impacted. In this area, we expect one in five wells to have unsafe levels of contamination.

This notice only applies to people who get water from a private well. If you currently pay a water bill, you may disregard this notice, because your water system is already being tested.

What are the health risks?

All drinking water may contain small amounts of contaminants. At higher levels, these contaminants may cause health risks.

In the short term, drinking water with too much uranium can cause kidney toxicity. In the long term, drinking water with too much uranium or radium – and drinking or bathing in water with too much radon – can increase the risk of certain cancers.

In general, the people most at risk of becoming sick are infants, young children, pregnant women, the elderly, and people whose immune systems are compromised because of AIDS, chemotherapy or transplant medications.

If you have concerns about possible health effects, contact your medical provider.
