Much of the tap water in developed countries is
harmful to a person's health in that there is
evidence of chlorine, heavy metals, pesticides, flouride,
and other health risks. Last I heard, tap water is legally
allowed to contain 11 contaminents and bottled water is
legally allowed to have 8. Maybe this has changed...
Either way, I feel safer with a little of both. Some tap
to build up resistence to impurities in my environment and
bottled for the pure stuff. I do like some of the eco-fleece
products made from recycled plastics....
