Hoax. Urban Legend. I don't know why some idiots send those messages around.

it's legit. it has something to do with the plastics.

don't drink it especially at this time with the extreme heat drink cold water

It is ok to drink water that has been left in a car in hot weather!

In the United States, plastic water bottles are regulated by the FDA as "food contact substances" and held to the same safety standards as food additives.

This means, among other things, that the FDA has reviewed test data on the safety of the plastics used in water bottles -- including the potential for hazardous chemicals leaching or "migrating" from the plastic into the water -- and established that they pose no significant risk to human health. The water itself is also tested and must meet basic quality standards similar to those set by the Environmental Protection Agency for public drinking water.

That is not to say that bottled water is absolutely free of contaminants, nor that chemical leaching never takes place. Studies done on water bottled in FDA-approved polyethylene terephthalate (PET), for example, did find trace amounts of potentially hazardous substances believed to have migrated from the plastic. The important point to take away, however, is that these amounts were very small and well within the safety limits set by FDA and EPA regulators.

According to Dr. Rolf Halden of the Johns Hopkins Bloomberg School of Public Health, consumers face a much greater risk from potential exposure to microbial contaminants in bottled water -- germs, to you and me -- than from chemical ones.

Note: Some versions of this message contain the additional false claim that pop singer Sheryl Crow claims she developed breast cancer as a result of drinking bottled water.

hoax. think about it. people get their drinking water that is sitting in "lakes" where the sun is shining on it all the time.
