Geologic Studies and Water Programs Drinking Water Protection Economic Geology Environmental Geology Hydrogeology Mapping Paleontology Stratigraphy Structural Geology Iowa's geology includes materials left by rivers, wind, glaciers, and marine environments, as well as the groundwater and mineral resources they contain. Investigations into the distribution and characteristics of these materials improve the quality and reliability of information and service provided statewide by the Geological Survey Bureau. These studies reflect both the practical application of geology to the environmental and economic issues of our time as well as the scientific research needed to close gaps in our basic knowledge of the state's geology. This information is essential to all who are concerned about resource availability, development, and protection in Iowa. Below, you will find these specific topics: (1) Drinking Water Protection Programs (2) Economic Geology (3) Environmental Geology and Hydrogeology (4) Mapping (5) Paleontology (6) Stratigraphy (7) Structural Geology The following information includes abstracts of technical reports.
