- Reuse of water bottles
Reusing water bottles is the practice of refilling and
reuseof plastic or glass water bottles designed for one use, with tap water for multiple uses.
Reusing single-use bottles is a common domestic practice. Typically the bottle is washed out with warm soapy water after each use. Periodically a bleach solution may be employed to kill bacteria. Washing and re-using bottles cuts down on
wasteand landfill, and drinking tap water is much less resource-intensive than buying commercially bottled water.Fact|date=September 2008
DEHA and dioxin urban legends
In 2001, a non-peer-reviewed paper (later a master's thesis) published by a graduate student at the University of Idaho [http://www.riskworld.com/Abstract/2001/SRAam01/ab01aa189.htm] reported that carcinogenic levels of a chemical known as DEHA may leech from
polyethylene terephthalate(PET) bottles when they are reused or heated. By 2003, this claim was being repeated by the news mediaand a viral emailcirculating on the Internet. The student paper referred to bis(2-ethylhexyl) adipate(also known as di(2-ethylhexyl) adipate), but the email and media reports confused it with diethylhydroxylamine, which is also known as DEHA.
According to the International Bottled Water Association, the student's finding of DEHA was likely the result of "inadvertent lab contamination"; it does not believe DEHA is released by PET bottles. It also asserts that PET has been cleared for food contact by the FDA, and so would not be a human health hazard, even if present. The
U.S. Environmental Protection Agencyand International Agency for Research on Cancer do not consider DEHA to be a toxic or carcinogenic chemical. (It was once listed under Emergency Planning and Community Right-to-Know Act (EPCRA), but has since been removed.)Coverage of origin and refutation: [http://www.snopes.com/medical/toxins/petbottles.asp snopes.com:Reuse of Plastic Bottles] .

The biggest risk bottle users are warned of is regarding to the bacteria that may develop in the bottle between uses. It is recommended to wash the interior with warm soapy water and let 100% dry before re-filling. Because cases of reinfection caused by reusing water bottles is not more prevalent, it is likely that the risk is low. The American Cancer Society has commented on this issue with this opinion. The New Zealand government officially issued a similar statement in response to public hysteria over their bottled water. Both of these opinions are readily available on line.Fact|date=March 2008
Other chemicals of concern
Bisphenol A(BPA) is a chemical of concern for water bottles, especially those intended for reuse and made of polycarbonate(which shares resin identification code7 with other plastics). High temperatures and bleaching are believed to increase leeching of BPA. The health impact for humans is disputed.
phthalates from PVC( resin identification code3) is also a concern, but PVC is not typically used for water bottles.
