Question

write a short note on the various sources of water​

Answer 1

Answer:Here are six sources of water:

Natural springs. In the olden days, one could just drink from a spring. Now, the water must be tested to be sure it is free of chemical toxins and purified of biological organisms.. To purify the water without adding anything, ozone is used. Ozone reduces to ordinary oxygen, which is normally suspended in water or released into the atmosphere. It is then bottled to make bottled spring water. If the water is naturally carbonated, then it is sparkling water.

Lakes and rivers. These days, these are quite polluted. But they are the source of tap water. Tap water is purified and disinfected, usually with chlorine. Sometimes fluoride is added. Some see this as preventing cavities, others believe it has health risks.

The ocean. Salt ocean water can be made drinkable through desalinization.

Streams, filtered or chemically decontaminated. This is how many campers get drinkable water when camping. Drinking water from streams without decontaminating it risks giardia and other illnesses.

Wells. Wells can be either near the surface or they can draw up water from very deep. They need to be tested for purity. But some wells offer pure, drinkable water.

Rainwater. Rainwater is actually pure. Of course, it may get dirty and contaminated by the roof or surface where it is caught, gutters or pipes, and storage. So, to drink it, either purify it, or stand in the rain, tilt your head up, and open your mouth.

Worldwide, 900 million people lack sufficient fresh, drinkable water.
