Question

which of the following would reduce water tables?
water pollution
snowmelt
overpopulation
flood

Explanation:

• Water pollution contaminates water but does not lower water tables.
• Snowmelt adds water to groundwater, raising water tables.
• Overpopulation increases demand for groundwater; excessive pumping depletes aquifers, reducing water tables.
• Floods add surface water that replenishes groundwater, raising water tables.

Answer:

overpopulation
