According to this page:
"The fact of the matter is by the time your water has reached boiling point (212°F / 100°C) all pathogens have already been killed! As a precautionary measure you may wish to boil for a full minute just to be safe. The time it takes for your water to reach a boil and then cool down is more than enough time to kill all harmful organisms that could make you sick.
To be safe you may wish to follow the advice of the US Environmental Protection Agency which recommends boiling for 1 full minute, or 3 minutes if you are 2000 meters above ground level"
According to this page:
If your well tests positive for E. coli, you should boil the water for at least one minute at a rolling boil before drinking it.
According to this page:
After the boil water advisory is lifted, will the water heater be contaminated?
A possibility exists, albeit small, that a pathogen may contaminate a water heater and survive (in a few cases, even grow), if the hot water temperature is maintained at 120°F or lower. However, because hot water directly from the water heater is usually not ingested, this should not be a safety concern. A water temperature of 140°F for a half hour should kill virtually any pathogens (including Legionella) in the water heater.

According to this page:
boiling does not kill ALL the bacteria, just MOST of them. Some bacteria are actually resistant to the temperature of boiling water (100 degrees C.). To kill all the bacteria, you need to raise the temperature to about 121 degrees C. To get water to this temperature, you must heat it under pressure. (You cannot heat boiling water in an open pot to anything over 100 degrees C.). In science labs, we use something called an autoclave to do this; at home you might have a pressure cooker in the kitchen.
