On my property I have both a well and a spring so that's what I generally use. Recent outing in the city reminded me of the chlorine they use. It was kind of an amusing episode as drinking the water at the restaurant I had sworn maybe the glasses weren't fully rinsed so the waitress brought out another and made sure it was clean.. still tasted of chlorine. So I had her fill my canister up thinking it was just a detergent they were using.. still tasted of chlorine so I presumed it must be the water and remembered that indeed chlorine/chloramine is added to public supplies. I don't know if that will prove to be a problem in the future and most things that claim to be are a bit on the tin foil hat tent that said a recent study does seem to show minimal impact on gut biome (https://doi.org/10.1038/s41564-022-01101-3) .. whether there is a compounding effect down line who knows.. but could explain some of the issues that differentiate between farm communities and urban dwellings (https://www.reuters.com/article/us-kidsallergies/amish-farm-...)
