Water fluoridation equipment has, on occasion, malfunctioned in the United States. Perhaps the worst incident in the United States occurred in Hooper Bay, Alaska in 1992. When fluoridation equipment failed, a large amount of fluoride was released into the drinking water supply and "296 people were poisoned; 1 person died,"[1] marking the "first reported death due to fluoride toxicity caused by drinking water from a community water system."[2]
