Which condition is required for rapid replenishment of an aquifer?

• A. Permeable soil
• B. Impermeable rock
• C. Heavy clay layers
• D. Constant droughts

Answer: (A)

Rapid replenishment of an aquifer depends on how easily water can move from the surface down into the groundwater. Permeable soil lets water infiltrate quickly, so rain and surface water can seep down and refill the aquifer faster. When the surface is covered by impermeable rock or thick clay, water can’t pass through easily, which slows recharge. Droughts reduce the amount of water available to recharge, but they don’t improve the soil’s ability to let water through. So, the key condition for rapid recharge is having a permeable layer that allows water to infiltrate efficiently.
