This is exactly opposite of what science says. New plastic actually leaches more compounds into water. As plastic gets old, its leaching capacity goes down. Old plastic is safer than newer plastic. However, most plastic bottles, including BPA-free are estrogenic. They are bad for men and women causing a variety of problems which are still poorly understood. The worse use-case is plastic filled bottles that have sat or have been transported in hot environments which is to say all of them. Ditto for hot takeout food served in plastic containers - soups, curries, etc. Do your research and don't fall to hoaxes that benefit vested industries that will profit from you not reusing water bottles.
