Where I live, the tap water is fine. Been drinking it for years and never had any problems with it.
Now one of my closest friends lives in Pittsburgh. Every so often, a boil water advisory is issued. Just had an advisory issued last week. The water system in the city is ancient, but the Democratic moonbat mayor would rather spend tax dollars on bike lanes than on upgrading the water system. Bike lanes are more important than the safety and well being of the residents.
