No county, city, town or village, including a county wherein a public authority owns both its public water system and the water supply for such system, that fluoridates a public water supply or causes a public water supply to be fluoridated, shall discontinue the addition of a fluoride compound to such public water supply unless it has first complied with the following requirements:
