I wonder why people in the USA have worry so much with water. You are USA and have water in your home with government inspection. You are fortunate to be born in the USA country.
Not all water utilities are government controlled, rather privately controlled. They're free to buy our elected officials who appoint government inspectors and look the other way.
Those that are publicly controlled may be rife with incompetence and/or be internally sabotaged by corporate interests that cripple them to push for privatization. See Flint Michigan.
