You may want to contact Customer Service at the NC Department of Environment & Natural Resources (assuming you are in North Carolina.) Their number is: 1-877-623-6748. Their Web site is located at: http://www.envhelp.org/.

They are very knowledgeable and should be able to connect you with the appropriate resources, depending on where you are located and what kind of water it is you would like to test (tap, well water, pond water, stream, etc), etc.

I hope this helps! Good luck!
