For 12 hours, excess hydrofluorosilicic acid was diverted to a 127-home community water supply. Fluoride levels peaked at 51 parts per million (ppm). Water acidification caused copper to leach from the domestic plumbing; raising copper levels to 25-41 ppm. Fifty-two (33 per cent) of those who drank hyperfluoridated water developed mild gastroenteritis. Vomiting was uncommon and symptom onsets usually occurred greater than 30 minutes after drinking water; suggesting that fluoride, rather than copper, caused illness. Skin contact with hyperfluoridated water caused itching and skin rashes.
长达12个小时，过量的氟硅酸被引入了一个有127户居民的社区供水系统。氟化物含量峰值达到百万分之51（ppm）。水体酸化导致铜从家用管道中渗出，使铜含量升至25 - 41 ppm。饮用了高氟水的人群中有52人（33%）出现了轻度肠胃炎。呕吐情况并不常见，症状通常在饮水后30分钟以上出现，这表明致病的是氟化物而非铜。皮肤接触高氟水会引起瘙痒和皮疹。
