Which side effect is directly caused by draining the groundwater from a region?

Ground water pumping is the side effect that is directly caused by draining the groundwater from a region.

Explanation:

The ground water depletion is caused by the sustained ground water pumping, deterioration of water quality, reduction of water in streams and lakes or land subsidence.

The negative effects of ground water depletion are Lowering of water table, increased costs, reduced surface water supplies, land subsidence and water quality concerns.

Pollution is the main causes of groundwater depletion. For example pesticides and fertilizers move to the groundwater supplies over time. Road salt, toxic substances from mining sites, and used motor oil also drain into groundwater.
