What do you do if your water is unsafe to drink and you live in an apartment?

Don't trust the tap like you used to, boiling is your best friend. I use Brita to prefilter the water, and then boil it, just to make sure. It sure beats drinking bottled water all the time, and the energy cost for boiling is nothing compare to the impact made through making of those bottled water. If you want to prepare for the emergency situation where tap is not available, but there are rivers and other raw water sources around, you can consider buying purification tablets. The tablets can kill most viruses and bacterias in the water, but it won't do anything to chemicals, so make sure the water source is free of pollutions. There are other options like a portal water filter, company like Katadyn, MSR are very good at making filters that can produce clean drinking water from a mud pool. Those filters are reusable, you can clean them many times before replacing. Overall many options are better than bottled water, and they have less impact on the environment. Bottled water might be good for the short term, but the wastes they created are not a sustainable solution.

they do the same herer in Vegas have for years and I think of every thing that goes into the toilet not just poo and p but people throw their neds down there even cig. butts I have a fiter on my tap so dont worry about it much. if in an apartment I would invest in that pitcher with a filter thing on it

i dont really drink tap water directly from the fusset. i only buy mineral water and have it deliver at home since im not sure about the tap water if its safe or not though i know its still a water but unlike mineral water. if theres no mineral water around then maybe i will just boiled the water and let it cool then put it in the fridge.

Just boil the water. That should remove the filth. U can wait for the water to cool to drink it. Or u could get a filter. But still...ex sewerage water 0_o ewww...
