Right to safe water. It means that the water in your kitchen faucet is expected/guaranteed to be safe to drink.

It must not have: noxious bacteria causing diarrhea, or liver parasite eggs, or mud, or mercury/heavy metals, or remains of faeces, or fracking methane, or pesticides, or medicines, or obesogens [1].

It must had been professionally filtered and treated to assure that none of those reach your home.

If you pay for water classified as "drinking water", you should not receive grey water, soapy bubbles, oily mud or anything else. This is the standard in all first country nations and I assume that it should be the same in US.

[1] And if in your small town everybody is obese, before to blame everybody for eating too much, or being lazy couch potatos, look for chemicals in the drinking water, leading to a broken satiety system, causing people to eat huge amounts of food. This is why the right to have safe drinking water is so important.

I don't think there's any reason to assume that obesity is caused by any specific chemical found in some but not all drinking water, in such a way that explains differences in obesity rates. If that were the case we probably would've figured that out by now and would be systematically treating drinking water to remove that chemical.
