Question

Groundwater is usually mixed with many minerals. Sometimes, the water is salty and sometimes
it is sweet. This difference is because of the minerals which are dissolved in the groundwater.
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 changes. In many mandals of Telangana,
there is 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, which affect our bones,
teeth etc. (Fig 3.5). In such situations, the drinking water should be properly treated to remove the
excess minerals. Many times, water is polluted due to the excessive use of fertilisers, pesticides or
poor drainage. In our country this problem is increasing day by day. Unless we take the preventive
steps, most of the wells or river water soon will become unsafe for drinking or even for bathing.
