Having lived here for more than twenty years i can say that although the tap water in argentina is relatively safe, i would still avoid drinking it for a number of reasons.
If you live in an apartment your building probably has two water tanks, one in the basement with a pump and one on the roof and while maintence in some buildings is ok i will bet if you asked when the last times those two tanks have been sanitized or tested for safety would receive the answer i dont know.
If you live in a house the odds are the last time anyone ever even looked at your roof tank is the day someone installed it .
so even though the water coming out of the water company is safe your own house or apartment is probably at least one source of conatanimint so if you dont boil the water you receive in your house for human consumption you are asking for trouble. And alway drink bottled water or at least boil the tap water and then put it in fridge to cool
