1.	“Sometimes the water is sweet and sometimes salty.” Explain the reasons for this. (or) The groundwater in some areas is salty and in some areas it is sweet. Why?
Answer» This difference is because of the minerals which are dissolved in the groundwater which is usually mixed with many minerals. These minerals come from the rocks and soils underneath. Hence, depending upon the minerals which mix with the water, the taste and nature of water change. In our state many mandals in Prakasam, Kadapa, and Ananthapur there is an excess quantity of certain minerals like Sodium, Fluoride, Chloride, Iron, Nitrate, etc. Drinking such water is not good for our health and can cause diseases that affect our bones, teeth, etc. In such situations, the drinking water should be properly treated to remove the excess minerals.
