An excellent info resource about fluoride in drinking water is Fluoride Action Network http://fluoridealert.org/

There is plastic in most water around the world: https://www.theguardian.com/environment/2017/sep/06/plastic-fibres-found-tap-water-around-world-study-reveals
Surprise, susprise, some plastics are flouropolymers and DuPont is involved:
“In 1938, polytetrafluoroethylene (DuPont brand name Teflon) was discovered by accident by a recently hired DuPont Ph.D., Roy J. Plunkett. While working with tetrafluoroethylene gas, he noticed that a previously-pressurized cylinder had no pressure remaining. In dissecting the cylinder, he found a mass of white solid in a quant i ty similar to that of the tetrafluoroethylene gas. It was determined that this material was a new-to-the-world polymer. Tests showed the substance was resistant to corrosion from most substances and had better high temperature stability than any other plastic.” (from: https://en.m.wikipedia.org/wiki/Fluoropolymer)
How much of the plastic in the water (which municipal water treatment facilities do not filter out) is flouropolymer?
