So I used some Montreal municipal tap water to clear my sinuses out on Monday (it's Friday now) and am now completely preoccupied with worrying about whether I have Naegleria fowleri or not. So, is it possible that there would be any in Montreal tap water? The temperature at this time of year is around -5 degrees C most of the time, but it does get a bit hot in the summer (I'm not sure what the water temperature of the surrounding water usually is). I can taste that the water is chlorinated also, but I read somewhere that this doesn't necessarily stop them. Anyway, I know it is unreasonable to be worried about this, but if anyone could let me know, that would be great!
