fluorine poisoning in water is well recorded
1)hooper bay Alaska 21 to 23 may 1992 level 100 ppm hundreds in hospital one dead reference Gessner et al 1994
2)los lunas new mexico 1980 at a school reference hoffison r 1980
3)Mississippi 1997 when the f content may have been as low as 40ppm reference penman 1997
4) Iceland 1700 about two thirds of the livestock and about a third of the population died of fluorine poisoning from an eruption
5) toothpaste about 500 ppm but it is not ingested it is also stabilized between 1990 and 1994 628 people were hospitalized for eating toothpaste

again the solubility of NaF in cold water is 4.22% or 42200 ppm of which about half will be fluorine
