Kansas state Rep. Jim Minnix, R-Scott City, who farms in Scott County, says that issues contributing to the depletion of the Ogallala Aquifer should have been dealt with a long time ago.
In a new report, scientists say the U.S. is facing serious challenges as groundwater is depleted in many areas. They call for a national effort to safeguard aquifers.
The groundwater that supplies farms, homes, industries and cities is being depleted across the world, and in many places faster than in the past 40 years, according to a new study that calls for ...
Overdrafting in coastal regions can lead to the reduction of water pressure in an aquifer, allowing saltwater intrusion. If saltwater contaminates a freshwater aquifer, that aquifer can no longer be used as a reliable source of freshwater for settlements and cities. Artificial recharge may return fresh water pressure to halt saltwater intrusion.
The Division of Water Resources within the Kansas Department of Agriculture governs the use and allocation of the state's water resources; regulates the construction of dams, levees and other changes to streams; represents Kansas on its four interstate river compacts; and coordinates the National Flood Insurance Program in Kansas.

Aquifer compaction is a significant concern along with pumping-induced land subsidence. A large portion of the groundwater storage potential of many aquifers can be significantly reduced when longterm groundwater extraction, and the resulting groundwater level decline, causes permanent compaction of fine sediment layers (silts and clays).
Water levels in the Ogallala Aquifer continue to plummet as farm irrigation swallows an average of more than 2 billion gallons of groundwater per day statewide.
The first environmental effect is increased crop growth, such as in the Rubaksa gardens in Ethiopia The irrigation that grows crops, especially in dry countries, can also be responsible for taxing aquifers beyond their capacities. Groundwater depletion is embedded in the international food trade, with countries exporting crops grown from ...
