I called Orange County Utilities, Water Division, and got answers to some of my questions. For the remaining questions, they gave me the e-mail address of one of their water quality people who hopefully will be able to answer them.
Basically, Orlando area water is considered "moderately hard", with measurements of 7.7 "grains/gallon" (I don't know what that means). I live in south Orange and the water there measures 7.8 grains/gallon and/or 133.2 ppm.
The OCU water quality web page has a link to the 2010 Water Quality report in PDF format, which contains an analysis of the water provided by each processing plant. For the report itself, click

One key piece of information that is, strangely, missing from the report is water pH. That's one of the questions I've asked via e-mail.
So far for brewing I've been using Crystal Springs Natural Spring Water, which I can get quite inexpesively from Costco. I got a copy of their water analysis. To get it, click

I don't do all grain yet. I've been doing partial mashing. However, I'm going all grain with my next batch, so mash pH will be of more importance. And, quite frankly, while it's quite convenient and inexpensive to use bottled water, I'd like to use the local water instead. Call me crazy...
