Here is what I want to know, were the bottled water company getting the water they put in the bottles? Is this the tap water run thru a filter? I use tap water to brush my teeth, and wash dishes with it. I have not noticed any adverse health conditions as of yet. The water that comes out of my tap is clear, free of debris, and has no bad smell. I think it would be safe to drink and cook with, but I would like it to be cold, but that’s asking too much. I will continue to experiment with this. Maybe I will get Brita Pitcher type filter and try drinking it, after I chill it in the Ref.
