Groundwater mining has had a significant impact on the Ogallala Aquifer. Over-pumping of the aquifer has caused water levels to drop drastically in some areas, leading to a decrease in water availability and an increase in the cost of pumping water. In addition, the decrease in water levels has caused a decrease in water quality, as the water that remains is often more saline and contains higher concentrations of dissolved solids. This has caused a decrease in crop yields and has had a negative impact on the environment.
