Environmental Health provides a variety of water testing services for citizens who are served by well water. Click this link to request samples Here.
Radon, Uranium, and Radium
Recent news from neighboring counties has increased the awareness of these naturally occurring substances in ground water. Wake County found wells with unsafe levels of uranium, radon and radium in the water. These substances occur naturally in the rock located underground. They sent out notice to inform residents about the naturally-occurring groundwater contaminants found in the eastern area of Wake County so that well owners could decide what actions to take about water treatment.
The State Laboratory of Public Health has an Environmental Radiochemistry unit that can analyze the gross alpha, gross beta, and uranium. This office is working with the state lab to make those sample kits available to us to assist well owners in Orange County who want this specialized sampling.
Well owners may also contract with a certified laboratory for retail testing that may be more comprehensive. These are some companies that we are aware can provide those services.

Hexavalent Chromium is a carcinogen caused by the natural leaching of mostly volcanic rocks in aquifers across the Piedmont region of North Carolina. Contamination stems from water-rock interactions that are common across the region. This is not limited only to wells near coal ash ponds.
Testing for Hexavalent Chromium
Hexavalent Chromium and Coal Ash panel are special order kits. Hexavalent Chromium is a time sensitive kit because it contains a preservative. We only order the kit when a sample is requested. We send all of our samples to the state lab. Health Department staff have to collect the samples using the kit and ship to lab to maintain chain of custody.

NOTICE **If you reside in the American Stone Company area or within 3000 miles of the former Orange County Landfill near Rogers, well assistance may be available.
