Iowa's Groundwater Basics
A Geological Guide to the Occurrence, Use, and Vulnerability of Iowa's Aquifers

While 80 % of Iowans rely on groundwater for their drinking water supplies, few are aware of the underground conditions that supply water to wells or affect its vulnerability to contamination. This new 83-page, full-color book published by the Iowa Department of Natural Resources takes a statewide, in-depth look at the geological basics of Iowa's groundwater resources - what they are; where they occur; how they behave; where they are vulnerable; and how they are used. The book is illustrated with numerous photographs, maps, and illustrations and is designed to meet the need for increased public understanding of the state's vital but largely unseen groundwater resources. Iowa's Groundwater Basics is free, $2 charge for shipping and handling. [click here for order form]
