Technically a "rolling" boil for just over 5 minutes will make water potable.
If you are unable to boil the water, a capful of chlorine bleach to a gallon of water will give you approximately the same thing. There are also water purification tablets which can be added to water.
Bear in mind these things only kill giardia and viruses and most biological contaminents, they will not remove chemical or synthetic contaminants like fuel oil or petrol or pesticides and things like that if they are present.
Best thing to do is to use a water filter designed for camping, if one is available, like a PUR.

First the water should be filtered to remove sediment and gross contamination. Then it should be boiled in a clean container and stored in clean vessels. If complete sterility is desired, that involves a trained and experienced staff and an enclosed facility designed specifically for producing significant numbers of sealed vessels in which the water is stored. If the water is meant for cooking, washing and drinking, then this level of sterility is unnecessary.
