Bisphenol–A (BPA)

A primary benefit of glass packaging is that it is not plastic, and in particular, polycarbonate plastic, which is made from a very controversial chemical called bisphenol-A. For bottled water, most of the larger 5 and 3 gallon, plastic bottles that go on water coolers, are polycarbonate. You can identify polycarbonate bottles by the #7 recycle code on the bottom of the bottle.

Bisphenol-A is a known endocrine disruptor as it mimics the natural hormones, in particular estrogen, throughout our bodies. In hundreds of independent scientific studies, BPA has been linked to numerous diseases including breast cancer, prostate cancer, diabetes, and heart disease.

Many governments, including Suffolk County, NY and Canada, have taken action by banning all products with BPA intended for children under the age of three. In January 2010, the United States FDA, after years of stating BPA was safe, changed its position to say that the chemical is of “some concern”.

Limiting your exposure to BPA is very difficult as this chemical is in so many products. In addition to polycarbonate water bottles, BPA is used as a liner in metal cans, dental sealants, compact discs (CD’s), cell phones, computers, even on credit card receipt paper.

With the many choices you have for water, one choice that is simple is to choose a product that is not packaged with polycarbonate plastic, but in GLASS, Mountain Valley Spring Water!
