Anyway.. read on..

This may be very true.Do you know chemical released by plastic water bottles can cause cancer ?
It is not the water that will affect you but the chemical released from the bottle.
The next time you get a bottle of mineral water, do check for a triangular sign on the base. You will see a number in the triangle. If the number is higher than or equal to 5, then this bottle is safe for more than one-time use.
Whatever number under 5 will release the chemical. Most mineral / drinking water bottles are made for one-time use and you will notice they are marked 1.
So, do check and do not reuse such bottles marked 1.

But then.. when i went to search for it...

Reusing Plastic Water Bottles

Rumor:This email begins by saying “Many are unaware of poisoning caused by re-using plastic bottles,” and says “bottles are safe for one-time use only; if you must keep them longer, it should be or no more than a few days, a week max, and keep them away from heat as well.” The email says the bottles contain DEHA, which it calls a potential carcinogen.

Fact:This email apparently relies on a student’s college thesis to make scary claims about water bottles. In fact, DEHA is not inherent in the plastic used to make these bottles, and even if it was the U.S. Environmental Protection Agency (EPA) says DEHA "cannot reasonably be anticipated to cause cancer, teratogenic effects, immunotoxicity, neurotoxicity, gene mutations, liver, kidney, reproductive, or developmental toxicity or other serious or irreversible chronic health effects." Meanwhile, the International Agency for Research on Cancer (IARC), says diethylhexyl adipate "is not classifiable as to its carcinogenicity to humans."
