"Here in Sweden we decided against fluoride for this reason and the fact that it is in fact toxic."
All water collected from natural sources contains some level of fluoride and other salts (which varies greatly from place to place). Does then your local water authority remove these naturally-acquired chemicals?
Generally not, but we choose where we take our from water from.
If there's too much fluoride in the rock water we take soil or surface water instead, for example. If there's too much fluoride in the water we do not supply it to people's taps, but this is for values like 4 mg/L.
So we mostly don't take any measures. In Stockholm it's apparently less than 0.2 mg/L though.
Is 0.2 mg/L the upper limit in Stockholm?
