For those who are curious and don't know, the reason for a boil water notice after a pressure drop is as follows:
A drinking water pipe system is not necessarily water tight. As long as it is under 40 + psi internal pressure the flow of water will always be from inside the pipe to the outside if there is a leak. Once the pressure falls, ground water may begin leaking into the pipe. This can allow the introduction of disease causing organisms. The groundwater may be contaminated from many sources including septic tanks etc. There are even many instances when the drinking water pipe is buried in the same trench as the sewage pipes which are far from water tight. There are design specs for such cases but in areas where the groundwater is high seasonally this is a concern under low pressure scenarios. And then there is the Saturday afternoon sixpack plumber who has been to get a case of beer and then to Home Depot and some how manages to plumb his commode so it comes out the drinking water facet (true story). If you live next to this guy he has the potential of contaminating your house when pressure falls.
The reason boiled water tastes bad is two fold. First is that you are a lousy cook and can't even boil water
and secondly is that you drive off the dissolved air. You can use a mixer to froth the water back up after it cools and it will taste better. If you are going to keep some boiled water around for a few days then you should keep it in the refrigerator so bacteria do not grow in it.
The people most at risk from contaminated water are infants whose immune system is not fully active and other suppressed immune system people.
P.S. All hospitals are required to have a back up water supply just for cases such as this.
