Water Bottles

On my own radar lately is what kind of water bottle to take to they gym, or to class, or in the car. 

A May 2008 Consumer Reports article warned against bottles that contain Bisphenol-A (or BPA).  A few months later, the FDA released its finding that BPA is safe.  But in 2009, an international group of scientists rejected the FDA's conclusions, and also questioned the EU's position on BPA safety. From a JSOnline article:

"It is becoming undeniable that BPA is dangerous," said Laura Vandenberg, a developmental biologist at Tufts University, one of 58 scientists from around the world invited to the conference in Germany. "The FDA's standard for safety is reasonable certainty. It is no longer reasonable to say that BPA is safe."

So this past January, the FDA changed its mind, at least a little, after a September 2008 National Toxicology Program report expressed "some concern" about BPA:Bpaconcern

The NTP has some concern for effects on the brain, behavior, and prostate gland in fetuses, infants, and children at current human exposures to bisphenol A.

The NTP has minimal concern for effects on the mammary gland and an earlier age for puberty for females in fetuses, infants, and children at current human exposures to bisphenol A.

The NTP has negligible concern that exposure of pregnant women to bisphenol A will result in fetal or neonatal mortality, birth defects, or reduced birth weight and growth in their offspring.

The NTP has negligible concern that exposure to bisphenol A will cause reproductive effects in non-occupationally exposed adults and minimal concern for workers exposed to higher levels in occupational settings.

Stainless bottle So . . . what water bottles do I use? 

Polycarbonate? Polycarbonate has been shown to leach BPA, so now there are clear plastic bottles that are BPA-Free.  According to an article on water bottles on the Natural Resource Defense Council website, however, only the manufacturers know what the replacement plastic is.  Stainless steel?  I'm going with that for now.  But I'm finding that the stainless steel bottles so far don't fit in my car cup carriers -- too wide for the coffee cup holder, and not quite wide enough for the other ones.  Time to get out the bicycle.
