Our tap water is drawn from a river and treated. It is undoubtedly
safe and wholesome, but the flavor is slightly sour and tainted with
chlorine. I fill a Brita pitcher from a sink-tap filter, and keep it
in the refrigerator. The result is perfectly drinkable, so I use it
to refill the bottled-water bottles I still occasionally buy.

Are these bottles made from bisphenol A?
