Jordan Aquifer

[edit]

The Jordan Aquifer is the third largest source of groundwater in Iowa.[1] It extends from northeast Iowa to south central Iowa, and is ultimately the source of much of Iowa's agricultural and industrial water. In addition to pollution threats, the aquifer is threatened by overuse in well-source irrigation, ethanol production[2] and the diminishment of resupply caused by extensive field tilling. The aquifer has dropped by as much as 300 feet since the 19th century, resulting in dry wells, the disappearance of natural surface springs, and the diminishment of water quality.[3][4]
