Explain the process by which surface water becomes groundwater. Use the terms 'infiltration' and 'percolation' in your answer.

Surface water infiltrates the soil and percolates through the unsaturated zone to become groundwater.

Describe the difference between an aquifer and an aquitard. How do these layers affect the movement of groundwater?

An aquifer is a permeable layer that allows groundwater to flow easily. An aquitard is an impermeable layer that restricts groundwater flow.

Imagine you are designing a well for a community. What factors would you consider to ensure a sustainable supply of groundwater?

Factors include the depth of the aquifer, the recharge rate, potential sources of contamination, and the rate of water withdrawal.

Explain how human activities can impact the quality and quantity of groundwater resources. Provide at least two specific examples.

Human activities like excessive pumping can deplete groundwater levels. Pollution from industrial waste or agricultural runoff can contaminate groundwater.
