If there is any question about the purity of your own drinking water, you should boil it. Water is so easily contaminated. It soon becomes unfit for human use. Do not be deceived .Water that may look pure may be full of germs that you cannot see. If you have your own well, you should have the water tested by an expert from the public health department in your area.

City water supplies are not always safe, especially during the drier times of the year. Boiling the water for minute will destroy all harmful germs. That is why hot drinks are safer to use when you are away from home. But wherever you are, you must remember that the purest water can easily be polluted unless it is kept in clean vessels.

One of the best chemicals for purifying drinking water is known as calcium hypochlorite. This is now supplied in ampoules, one half gram ampoule being sufficient to purify thirty-six gallons of water. This is the process referred to as chlorination. Any good household bleaching solution will serve this purpose. They all contain sodium hypochlorite. Just add ten drops of bleaching solution to each gallon of water. This will destroy all the bacteria within half an hour. One quart of the bleaching solution will purify 1500 gallons of water. These bleaching solutions are simple and inexpensive. They are also quit safe.
