Rain and snow are the original sources of all our drinking water. Raindrops are formed from the heavy vapor that arises from the sea. As the clouds pass over the land, they condense into drops of rain or flakes of snow. We are all familiar with the fact that a rainstorm clears the air, washing it clean and free from dust and smoke.

Raindrops are usually free from germs, although they may contain a little dust and perhaps a few harmless microbes. Trouble starts when the raindrops strike the surface of the earth. The rain that collects on cultivated fields, farmyards, and city streets may contain many different kinds of germs, some of which are harmful to man. Many of these germs found on the ground have come from the digestive organs of animals and human beings. These are the bacteria that often cause serious intestinal diseases.

But the trouble is not always with water that falls onto the ground. People who use tanks and cisterns must also be careful. Roof water may be almost as badly contaminated with germs that have found their way there by dust blowing up from the street. There is also the problem of germs from the droppings of birds. Tank or cistern water should always be boiled or sterilized. (more…)

Living in a large city is not always safe. Wherever large numbers of people are gathered together, there is always some risk of infection. During an epidemic it is easy for disease to spread quickly from one person to another. The more dense the population, the greater the danger.

Out in the country the risk of infection may be somewhat less. The protective forces of nature often help to prevent disease. Many germs are destroyed by the heat of the sun and by the drying effects of the wind. The cold days of winter may also help to eliminate some harmful bacteria. But a few germs may still be there after the snow has melted. This is more apt to be true where the winters are short and relatively mild. (more…)
