FAQs on Different Types of Geological Formations of Groundwater Video Lecture - Civil Engineering Optional Notes for UPSC

1. What are the different types of geological formations that can store groundwater?
Ans. Some of the common geological formations that can store groundwater include aquifers, fractured rock formations, alluvial deposits, and karst formations.
2. How does the porosity of geological formations affect the storage of groundwater?
Ans. The porosity of geological formations refers to the amount of empty space within the rock or sediment that can hold water. Formations with high porosity, such as sandstone, are able to store more groundwater compared to formations with low porosity, like clay.
3. What role do geological formations play in the replenishment of groundwater sources?
Ans. Geological formations act as natural reservoirs that can store and release groundwater. When precipitation infiltrates the ground, it percolates through these formations, replenishing underground water sources.
4. How do geological formations influence the quality of groundwater in a particular area?
Ans. Different geological formations have varying degrees of permeability and can affect the movement of contaminants through the groundwater. For example, porous formations may allow pollutants to easily seep into the groundwater, impacting its quality.
5. What are some examples of geological formations that are particularly important for groundwater storage in India?
Ans. In India, formations such as the Deccan Traps, Gondwana basins, and alluvial plains of major rivers like the Ganges and Brahmaputra play a crucial role in storing groundwater and supporting agriculture and drinking water supply.
