I contacted my water company and they said they'd be happy to send me a report and asked me to specify what I'd like to know specifically. This kind of threw me cause I'd really like to know *everything*, but I'm trying to come up with a list...been searching various posts and this is what I've come up with. If you have anything to add, I'd appreciate it!
Alkalinity as CaCO3
Hardness as CaCO3
Total Dissolved Solids
Some of these are probably not necessarily related to brewing...but I'm also just curious how much lead and arsenic is my water.
