I am not sure about the Raleigh area. There is an aquarium club there so you may want to do a search for it. Perhaps this one will get you there.
I live in Brunswick County in the SE corner of the state. The county does the sanitary district at this time and the water details are available on the county website. I did an e-mail the Brunswick County water district people and they responded right away when I was trying to figure out my pH questions.
