What tests should I have?

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 costs $175 and includes testing for: 

  • Coliform Bacteria
  • Inorganics
  • Volatile Organic Compounds, and 
  • Pesticides.

In addition to these tests, if you live in certain parts of the county, Wake County recommends testing for radiological contaminants. The "Rads Package" includes uranium, radon in water, and gross alpha activity and a kit for testing your indoor air for radon. This package costs $140. 

What if I can't afford testing?

Wake County offers discounted testing for households with incomes less than 2.5 times the federal poverty guideline - about $65,500 for a family of four. Find out if you qualify and apply here.

How do I get my well tested?

To submit your request for well testing, visit the Wake County Permit Portal.
Read instructions here for requesting well water testing using the Permit Portal. 

You can also have your water tested by a lab that is certified by the N.C. Division of Public Health.  

What if testing finds a problem?

While discovering a problem in your drinking water can be scary, the good news is that nearly all well water problems can be fixed. Fixing the problem could mean disinfecting the well, repairing the well, installing a filter to remove contaminants, or another solution. After you get your test results, Wake County Environmental Services will work with you to help you understand your options and will help connect you to resources to address the problem.

My well water tastes, smells, and looks fine!

While tastes, odors, discoloration, or cloudiness are obvious signs of problems with your water, water that is perfectly clear and tastes fine can still have unhealthy levels of contamination. Testing by a certified laboratory is the only reliable way to be sure you have safe drinking water.

I already had my well water tested.

Do you know what it was tested for? Was it tested by a certified drinking water laboratory? Most free test kits do not check for chemicals that can affect your health. Without a complete test by a certified laboratory, you may be drinking water with contaminants that you cannot see, taste, or smell.

My well water tastes, smells, or looks bad.

If you are having any of these problems, now is a perfect time to find out exactly what is in your water. A complete water test will help you get the most out of the money you invest in your well or a water treatment system by ensuring that you have addressed all of the problems – visible and invisible – with your water.

Can I collect my own water samples?

You can collect your own water samples for bacteria and inorganic tests, but water samples for most other tests must be collected by Wake County staff. If you would like to collect your own samples for bacteria or inorganics testing, you may do so by obtaining sample containers and instructions at the following locations:
