What might cause a well to hold less water each year?

Question

1. An earthquake shifted the aquifer to a new spot.
2. The aquifer has slowly become dry over time.
3. The rocks in the well became harder.
4. The groundwater reaches freezing temperatures.

Answer 1

2. The aquifer has slowly become dry over time.

Over time, the water levels in an aquifer can decline due to various reasons such as overuse, excessive pumping, or changes in precipitation patterns. This can decrease the amount of water available to a well each year and eventually lead to the well running dry.
