Test of water

Generally, we find two types of water, such as sweet and saline (salty). The taste of the water of oceans and most of the natural lakes are salty. The groundwater is sweet, and it is drinkable water. Most of the water is saline only a few percentages of water are sweet. The 75 percent area of planet earth is covered with the water.
           But our of 75 percent only 2.5 percent of water is drinking water. Most of the drinking water is in the form of groundwater. The taste of water is originally sweet. It becomes saltish when it contacts the mineral salts while flowing and passing through the land.

Source of water

          To be specific water is only obtained from two main sources such as rain and ice. Most of the drinking water present on the earth is in the form of ice. During the rainy season, clouds rain a lot of water, this is the process of condensation. This is a cyclic process. During the months of the summer season, ice melts on the mountain and flows downward.

Reservoirs and carriers of water

          There are two types of reservoirs. One is natural reservoirs and the other is artificial reservoirs. The artificial reservoirs are men made reservoirs. This mane mad reservoir is made for the purpose of storage and conservation of water. The Lakes, seas, ponds, and oceans are the natural reservoirs of water.
         There is a constant flow of water in the streams and rivers. These are the natural carrier of water. The water of streams and rivers is clean and fresh. People get water generally from ponds, wells, rivers, and canals. Well, and ponds are also made to procure water for the need.
