Question

The characteristics of aquitards differ from aquifers mainly by

• A. Zero porosity
• B. Low permeability
• C. No storage
• D. High compressibility

Hint:

Groundwater formations: \[ \boxed{ \begin{aligned} \text{Aquifer} &\rightarrow \text{High permeability}\\ \text{Aquitard} &\rightarrow \text{Low permeability}\\ \text{Aquiclude} &\rightarrow \text{Nearly impermeable} \end{aligned} } \]

Answer 1

The Correct Option is B

An aquitard is a geological formation that stores groundwater but transmits it only very slowly because of its low permeability. Unlike aquifers, aquitards do not readily yield water to wells. Hence, \[ \boxed{\text{Low permeability}} \] is the correct answer. Therefore, \[ \boxed{(B)} \]
