Consider the following statements regarding ground water : 1. Ground water is exhaustible and is evenly available. 2. Natural replenishment of the ground water resource is a very fast process. 3. Ground water is generally better than surface water in respect of biological characteristics. Which of the above statements is/are correct ?
- A1 and 3 only
- B2 and 3 only
- C3 onlyCorrect
- D1, 2 and 3
Solution
Concept
Features of groundwater
Step-by-step solution
1. Groundwater is not evenly distributed (statement false). 2. Natural recharge is slow (statement false). 3. It is usually free from pathogens because of natural filtration (statement true).
Explanation
Groundwater is generally biologically purer than surface water, but its availability is uneven and its replenishment is slow.
Why the other options are wrong
Options with statement 1 or 2 are wrong.
Shortcut
Groundwater: uneven, slow recharge, biologically safer.
Common mistake
Assuming even availability.
Correct answer: C) 3 only
