Problems caused by overpumping are declining water levels and subsidence.

• A. True
• B. False
• C. Not sure
• D. Not applicable

Answer: (A)

Overpumping creates a cone of depression that pulls water from the surrounding aquifer, causing the water level to fall. When pumping exceeds how quickly the aquifer can refill, the water table drops, which is the “declining water levels” part. In confined or compressible aquifers, long-term overpumping can force the sediment grains to compact, leading to permanent land subsidence. These outcomes—lower water levels and subsidence—are classic, well-documented consequences of extracting groundwater too quickly. So the statement is true. In practice, managing pumping and boosting recharge can help prevent or lessen these problems, but their occurrence under excessive pumping is the standard expectation.
