Not sure what you mean by drinkable tap water. All tap water is drinkable. Some is definitely better than others. Hawaii consistently ranks #1 for the cleanest water based on EPA safety and purity. Believe it or not, New York has the best-tasting tap water! A filter on your faucet is best. Or you can get a tabletop filter. These work amazing!! https://a.co/d/08x8BRYf
