Dangerous water bottles?

After listening to some zealot explain the dangers of plastic water bottles to me, I looked up some information here.

The net of this is that this is a problem with the expensive, Nalgene-type water bottles. These have a "7" in the recycling triangle.

I checked the water bottles cluttering up my bicycle area. I got them all free because they advertise Amlings Cycle, the North Shore Century, Evanston Northwestern Healthcare, REI, Village Cyclery and other similarly fine institutions. They are evidently free of harmful BPA as well. They have either "4" or "2" in the recycling triangle.

The BPA problem does not apply to all Nalgene bottles currently sold. I threw out the older Nalgene I used for foreign travel.
