I'm on a well and have been on one most of my life. Water from my tap is excellent.
With that said I don't find this surprising at all. Anytime someone pours me a glass of city water I can smell the chlorine, I don't even have to taste it. Even if I go out and eat, I barely drink the water because to me it taste like chemicals. I can even taste the plastic in bottled water. I imagine people whom have been on city water for most of their life get used to it and don't noticel it.
Excellent and informative video though.
