Heck if I know! Most people don't discuss water parameters in daily conversation.
I'm in eastern Montana, USA. Lots of cows, not many people. Rolling hills, soft water with apparently a very high KH in well water. My neighbors' well is in a coal vein and it's super sulphur-y. Mine tastes great and seems to not have any issues.
