Question

In which layers is a leaky aquifer typically bounded by

• A. Impermeable layers
• B. Semi-permeable layers
• C. Clay layers
• D. Rock layers

Hint:

Aquifer types: \[ \boxed{ \begin{aligned} \text{Confined aquifer} &\rightarrow \text{Impermeable layers}\\ \text{Leaky aquifer} &\rightarrow \text{Semi-permeable layers}\\ \text{Unconfined aquifer} &\rightarrow \text{Free water table} \end{aligned} } \]

Answer 1

The Correct Option is B

A leaky (semi-confined) aquifer is bounded by one or more semi-permeable layers (aquitards). These layers allow a limited amount of water to pass through them. Hence, \[ \boxed{\text{Semi-permeable layers}} \] is the correct answer. Therefore, \[ \boxed{(B)} \]
