I'm not a purchaser of bottled water, nor to I have a need to denigrate anyone who does. I.E. I have no bottle in this stream.
That said, does Different Drummer really imagine that water-bottling is not a closed system? Does (s)he imagine that company employees stand over open tanks of water or hand-fill bottles from manually operated taps?
The thread was posted ~12 hours ago, just 4 Replies, none pointing out the grossly obvious flaw in the OP claim. Did Coca-Cola (= Dasani) or Perrier do something to PO DU-Denizens?
