Instead of getting the Ward test, I called the water authority in my county (Anne Arundel) and was directed to "Water Operations" and spoke with a very knowledgeable gentleman in charge of "water quality issues."
From him I got all the data I was looking for (Bru'n water spreadsheet) and the nitty gritty on where my tap water is actually sourced from. Plus he guarantee no chloramines are being used, and none of the county's water comes from open reservoirs (like Baltimore City/County), only deep local wells.
It could still leave a few question marks as to any change of water composition by the time it gets to
my faucets, such as where iron or lead pipes are used. I don't think that's an issue here, the water is soft and tastes fine, except for chlorine, and it's worse during the summer. So Campden tablets take easy care of that.
The water companies don't have to report the mineral composition beyond what is federally required (EPA), but they have the analysis data, and I'm sure they test it more than once a year.
