If So, you may have noted it is somewhat costly, but there are reasons why Its clarity and taste probably pleased you: Natural chemistry, rather than mere coincidence, accounts for the fact that virtually all of Americas fine bottled waters come from limestone springs. As they course through under­ ground limestone channels, they leach out and absorb C a 0 0 3 or calcium carbonate.
