In the past week a series of reports came out confirming that water bottles and such plastic products are not as safe as we would like them to be. Bisphenol-A (BPA), a chemical in the mix, is thought to mimic the effects of the hormone estrogen in cells and in more than 100 independent studies has been linked to increased incidence of cancer, obesity, and early onset of puberty in humans and developmental, neural, behavioral and reproductive harm in animals
... many people reuse disposable PETE plastic bottles, a study published in the Canadian Journal of Public Health in November 2002 confirms reused water bottles also make good breeding grounds for bacteria since thorough cleaning is difficult. Also, in one Italian study, the amount of DEHP, an endocrine-disrupting phthalate and a probable human carcinogen, in bottled spring water was found to increase after 9 months of storage in a PET bottle. However, it is unclear whether the levels detected could harm people drinking the water.
I have seen reports like this before, take a look at this part: In 1999, the Natural Resources Defense Council (NRDC) found that tap water is often better regulated than bottled water and has to meet more stringent standards at both the federal and local levels. In any case, among the thousand bottles tested by the NRDC, about one-fifth contained chemicals such as toluene, xylene, or styrene, known or possible carcinogens and neurotoxins ... One of the more surprising findings from the study is that a city's tap water cannot have any E. coli or fecal coliform bacteria, while bottled water is allowed a certain amount of these bacteria.
I've never been a big fan of bottled water but I do carry my water in a plastic bottle. I am going to go down to Mountain Co-op to see what they are suggesting to replace the plastic bottles now that they are pulling those off the shelves. I guess stainless steel would be the best solution ...
