It's funny though how the sell-by date is like one year into the future, yet on the bottle labels it says "Water that has seeped through glaciers into pure rock deposits for 5000 years" bla bla.

I guess the plastic they bottle the water in has something to do with it...

It's because after around two years the Carcinogens start to seep out of many thermosoftening plastics.

Perhaps even the same carcinogens that found their way into the extracted groundwater.

I heard an "expert" on radio last night say you should not heat food in a microwave in contact with plastic; as the chemicals in the plastic will get into the food.

Would acid soft drinks like Coke leach out chemicals from plastic bottles?
Would water?
Where do PCBs come from?

I can't really answer any of those questions directly with sources, but for a good primer on PCBs, check out the wiki.
Polychlorinated biphenyl - Wikipedia, the free encyclopedia

I think the most common cause of PCB pollution is old electrical parts and manufacturing. The biggest danger is dioxin as it is one of the major environmental pollutants found nearly everywhere.

My *guess* with coke in a plastic bottle is that you are polluting your body more with the coke than with any plastic residues that are leached. Plastic is a by-product of petro production and as it is used in "consumable" plastics it is very stable.
