When camping, travelling overseas, or even following some malfunction at your local water rehabilitation plant, you are urged to boil water before drinking it. How efficient is boiling - does it assuredly make the water safe to drink? And how long do you boil the water for?
Why Boil Water?

The main infer boiling is recommended as a water rehabilitation is because it can be done plainly and because the disease causing organisms are destroyed by heat. Holding the water at a high adequate climatic characteristic for long adequate will destroy pathogens. The organisms of interest are cysts such as cryptosporidia and giardia, and bacteria such as E.coli, typhoid etc. Although the boiling does not take off them from the water, it does kill them and thus they will cause no illness.
How Long Should Water Be Boiled?
There are many times suggested: 1 minute, 3 minutes, 5 minutes, 10 minutes etc. Some advocates even advise adding a tiny to the boiling time for each 1000 feet of altitude. So which of these times is correct? After all, the whole of time the water needs to boil determines the whole of fuel needed (to boil 1 litre of water requires about a kilogram of wood). As it turns out, none of them. You do not even need to boil it for one tiny - you just need to bring it to the point of boiling. Let's reconsider why.
According to the Wilderness healing Society, water temperatures above 70° C (160° F) kill all pathogens within 30 minutes and above 85° C (185° F) within a few minutes. So the higher the temperature, the less time is needed to kill the micro-organisms. Bringing the water to boiling point raises it well over the 85°C mark. Not only that, but the water must then be allowed to cool (unless you are production a cuppa). So the total time the water spends above 85°C is considerable and adequate to kill pathogens.
If it is adequate just to bring water to 85°C for a few minutes, why are you told to boil it? Basically because that is a foolproof way of guaranteeing the water will be the right temperature. Most people, do not carry thermometers with them when camping so it would be difficult to rule when the right climatic characteristic was met - once it reaches boiling you know what climatic characteristic it's at within a join of degrees.
How efficient is Boiling Water?
Boiling water is an efficient method for destroying bacteria and other pathogens. If the water is turbid, filter it straight through a clean cloth, or coffee filter to take off particulate matter before boiling as that will heighten its appearance.
Boiling will not contribute any safeguard against other things such as heavy metals, pesticides, herbicides, pharmaceuticals etc that may contaminate a water supply. It may take off chemicals which have a lower boiling point than water but what about the others? Neither does it take off turbidity, foul tastes and odours.
In short, boiling water does not purify your water. It is assuredly efficient at eliminating the target pathogens but will not be efficient against other contaminants - you assuredly need a decent water purifier for that. However, drinking boiled water is assuredly better than dehydration.
