[Answer] Why has groundwater use increased over time?

Answer: The principal reason for the increase of groundwater use is the increasing population. Urbanization and pollution have both contributed to an increase in the use of groundwater. Polluted rivers lakes and springs are no longer viable sources of groundwater. Urbanization has concentrated large populations in areas that might not have direct access to surface water or that might have a larger demand for freshwater than surface water can supply.
Why has groundwater use increased over time?

Direct effects. An irrigation scheme draws water from groundwater rivers lakes or overland flow and distributes it over an area. Hydrological or direct effects of doing this include reduction in downstream river flow increased evaporation in the irrigated area increased level in the water table as groundwater recharge in the area is increased and flow increased …

Groundwater is the main source of drinking water in many coastal areas of the United States and extraction has increased over time . Under baseline conditions the inland extent of saltwater is limited by higher pressure exerted by the freshwater column owing to its higher elevation.

Groundwater pollution (also called groundwater contamination) occurs when pollutants are released to the ground and make their way down into groundwater.This type of water pollution can also occur naturally due to the presence of a minor and unwanted constituent contaminant or impurity in the groundwater in which case it is more likely referred to as contamination rather than pollution.

Nitrate levels generally meet USGS water quality standards but continue to gradually increase over time . This trend can impact the future groundwater sustainability for portions of the aquifer. Aquifer water balance. An aquifer is a groundwater storage reservoir in the water cycle. While groundwater is a renewable source reserves replenish …

Such impacts include increased coastal erosion higher storm-surge flooding inhibition of primary production processes more extensive coastal inundation changes in surface water quality and groundwater characteristics increased loss of property and co…
