Hydrology, ground water, Mississippian, Iowa
The Mississippian of Iowa is a major bedrock aquifer underlying about two-thirds of the state. Water is found in secondary openings in carbonate rocks. Recharge is mainly from precipitation in the outcrop area. The water moves southeasterly through joints, fractures, and along bedding planes with the Des Moines River valley forming the principal line of discharge. The outcrop area of north-central Iowa has the most favorable conditions for obtaining large yields from wells. Only small supplies generally can be obtained from the aquifer in other parts of the state. Mineral analyses indicate the best quality water from the aquifer is found in north-central Iowa. High concentrations of sulfate and fluoride in the water restrict the use of the aquifer in southern Iowa and in parts of central and west-central Iowa.
