The U.S Military has been using hard plastic canteens (water bottles) for at least 40-50 years and I have never heard of an medical outbreak of any kind because of this. With millions of service men and women drinking out of these vessels over that amount of time, I would think that if there was a problem that it would have been announced.
We can only worry about so much stuff. This is one that I am not going to lose sleep over.
