Question

Explain how groundwater overdraft occurs and its likely consequences.
short paragraph

Answer 1

Groundwater overdraft happens when pumping from an aquifer exceeds the natural recharge from rainfall, rivers, or infiltration, so the water table steadily drops. It is commonly driven by intensive irrigation, growing urban and industrial demand, prolonged drought, and reduced recharge from land-use change. Consequences include falling wells and higher pumping costs, reduced baseflow to streams and wetlands (harming ecosystems), deterioration of water quality (saltier water, mobilized contaminants, and coastal saltwater intrusion), and land subsidence that can damage buildings and permanently reduce aquifer storage — producing long-term socioeconomic and environmental impacts.
