People don't die from lack of fluoride but their teeth aren't too pretty.

People do die from typhoic and cholera though.

Lough Mask isn't contaminated - it's one of the few pristine lakes left in Europe and all of Castlebar is supplied from Lough Mask - most of Mayo too nowadays. They have to add enough chlorine so that it doesn't evaporate by the time it gets to your tap. There are series of staging posts along the way to keep the levels just right. There's way less chlorine in Castlebar tap water compared with say New York - (which is also fed from a large pristine water source much more carefully managed than Lough Mask). But a lot more chlorine in New York water than Castlebar water.
