We don't drink the BWSL water. We drink from the old faithful 5 gallons. Many have told me that it is potable, but I smell a distinct chlorine aroma whenever showering or washing my hands (not quite pool strength, but there). We treat it as if it were rain water. We generally don't use it for drip coffee although we do use it for boiling water for pasta/rice. Everybody I meet has different guiledines. I also have been told that the Crystal 5 gallon water and the BWSL water are purified in a very similar way...
