Yes. All PET food containers such as water bottles contain trace (parts per million) amounts of acetaldehyde and lesser amounts of formaldehyde. These aldehydes are unavoidable byproducts or decomposition products of PET manufacture and bottle fabrication. Proper manufacturing conditions minimize the formation of these aldehydes.
