I think one of the main reasons folks prefer bottled water is taste, or
lack thereof. Municipal sources can taste pretty bad. They are also quite
complex in their origins sometimes, as in Los Angeles, which has a number
of independent water companies and aquifer or riverine sources. Interesting
politics. We are not all so fortunate as to live in NY or Atlanta in terms
of what comes out of the tap.
