Safe Drinking Water Bottles

I left the pack of bottled water in my dorm for the holidays and the room was very hot during this time because I had to leave the heating. Is it safe to drink ever?

If the bottles are still sealed then yes, they are beautiful. If they were open or they are not sealed bottles (like a sports bottle that you completed yourself) and not refrigerated, and then I throw them and make more.

OR IS IT DRINKING WATER treaties or PAKAGED (IE mineral water), it is very good. If it's just regular water, so why the doubt and drink. Using water for other purposes and freshwater use. VISTA
