Finding BPA Free Bottled Water Brands

By Marci Glover


People have embraced the convenience and perceived superior quality of bottled waters. However, the fact that most come in plastic concerns many consumers. Plastic is made of chemicals which can leach into food and beverages, especially when it is softened or degraded by heat. For this reason, many consumers are interested in knowing about BPA free bottled water brands.

BPA is an abbreviation for bisphenol A, a chemical component of polycarbonate plastics and epoxy resins. Many food containers are polycarbonate plastic, and epoxy resins are commonly used to line metal cans, bottle tops, and water pipes. Before bisphenol A began to be suspected of adverse effects on human health, both water and baby bottles were usually made of polycarbonate plastic.

The FDA, America's regulatory body for the food and pharmaceutical industry, says that the low levels of bisphenol A found in foods and beverages does not pose a significant health risk. For this reason, the chemical has not been restricted. However, consumer concerns over research that shows possible danger to children in the womb and up to three years of age have caused many manufacturers of infant and toddler products to produce BPA-free goods.

While the FDA continues its investigation of this chemical, it has published guidelines to limiting exposure to the chemical. Tips include warnings about putting plastic food containers in the microwave or in the dishwasher, since high heat can cause the plastic to break down. Another suggestion is to limit the use of canned goods.

This chemical mimics estrogen in the human body. It may interfere with proper development of the brain and the prostate gland in babies, and may cause behavior disorders. It is considered by some experts to be a carcinogen. Consumers have become increasingly wary, despite FDA assurances of safety. Europe has banned the use of BPA in all products for children under three.

Concerned consumers should look for pacifiers, infant formula bottles, 'sippy cups', and teething rings labeled 'BPA-free'. They may also want to avoid this chemical for their own use by carefully selecting foods and beverages packaged in plastic. Polycarbonate containers will have a '7' recycle code on the bottom.

It's relatively easy to find drinking bottles that are free of this chemical. These include glass or glass-lined bottles, metal ones, or plastic ones that aren't polycarbonates. However, getting information on particular brands of bottled water that comes in BPA-free bottles is more difficult. It does help to check the number on the bottom of the bottle. A number 2, 4, or 5 means that the container is made from a safer form of plastic.

If you want to make sure about a commercial brand, call the manufacturer directly and ask a customer service representative. The representative will be glad to tell you if the manufacturer's bottles are in fact BPA-free. Otherwise you can minimize exposure by using glass, stainless steel, or porcelain food and beverage containers.
