Day 115: Bottled Water: Refreshing Drink or Deadly Poison?

We have all seen it by now either via email from a friend or family member or in a posting on Facebook or Twitter alluding to the dangers that bottle water poses especially if frozen or left in a hot car.  Like everything we see on the internet it must be true, or is it?

First off these rumors are stacked like an answer in Boulderdash. Ever play that game? You are given a word and you have to provide the definition for the word. For each person who votes for your answer you move up the game board and whoever gets to the top first wins. 

Example: Acalculia

My Definition:  hormone that triggers the fall of autumn leaves in trees
Actual Definition:  inability to work with numbers

Get the idea.  The object is to sound authoritarian even if you have no idea what you are talking about.  So we read something impressive like, “The plastic in these bottles called polyethylene terephthalate or PET contains a carcinogen called diethyl hydroxylamine or DEHA.”  Now that sounds scary and it is followed by a warning, “This cancer causing chemical can leach into the water you are drinking especially when extreme heat or cold is applied.” Indeed we are warned that DEHA is so dangerous it can leach into your water simply by you reusing the bottle. 

Let’s apply a little common sense to the above implied situation.  Anyone who has ever worked in a warehouse or shipping environment can tell you that your bottled water, whether its Kroger brand or Fiji in the square bottle, is exposed to heat and cold many times before it even hits the store shelf.  It’s shipped in train cars and big trailers that I can assure you are in no way temperature controlled.  It’s stored in warehouses that are always hot in the summer and cold in the winter.  That means that if it were true you are drinking poison from the moment you crack the top on that bottle you just pulled out of your refrigerator. 

What We Know

The American Cancer Society has stated that DEHA is not found in the plastic used to make PET bottles.

The Environmental Protection Agency states that DEHA “cannot reasonably be anticipated to cause cancer…or other serious irreversible chronic health effects.”

The International Agency for Research on Cancer put out a statement explaining that diethylhexyl adipate “is not classifiable as to it carcinogenicity to humans.”

The American Chemical Council stated that “There is simply on scientific basis to support the claim that PET bottles will release dioxin (DEHA) when frozen,” and that dioxins “can only be formed at temperatures well above 700 degrees Fahrenheit; they cannot be formed at room temperature or in freezing temperatures.”

Lastly don’t take my word for it take the word of John Hopkins researcher Dr. Rolf Halden who said about the PET bottle controversy, “This is an urban legend.  There are no dioxins in plastics” and of the freezing myth that “freezing actually works against the release of chemicals,” since “chemicals do not diffuse as readily in cold temperatures.”

In Conclusion

I decided to tackle this health issue since it has popped up multiple times amongst friends I have on Facebook and among family.  Common sense and a little science go a long way in taking the scary out of something completely made up.  Bottom line, don’t be afraid of bottled water in the freezer or in the car.
