The Iowa Geological Survey Serving Iowans for our Economy, Environment, & Quality of Life
Groundwater Resource ManagementIowans rely on groundwater for drinking water, agribusiness, and industry—interests that sometimes compete for a finite resource. The IGS provides communities with vital information they need to make informed choices on water-related concerns, including quality and quantity.
“Utilizing the tools and knowledge of the IGS staff … has paid off for us.”
• todd SteIGerwaldt City of Marion Water Department
Geologic ResourceCharacterizationThe IGS provides scientific data supporting the classification, management, and conservation of Iowa’s geologic resources, including sand, gravel, soil, and aggregate resources. These are vital for the state’s stability and growth.
“The Iowa Geological Survey is an important resource for our ILPA members and Iowa’s aggregates industry.”
• randy olSon Iowa Limestone Producers Association (ILPA)
Research and PublicationIGS expertise includes subsurface geologic and groundwater modeling, mapping of earth and mineral resources, innovative geophysical techniques, and more. The study of Iowa’s geologic and water resources by IGS researchers provides needed information to support industry and economic growth.
“IGS is … the ‘go-to-source’ we depend on to provide reliable information and direction.”
• Sherm lundy Upper Cedar Watershed Management Authority
Outreach and EducationIGS researchers travel the state each year, visiting classrooms, Stem festivals, and other events to educate Iowa students and raise awareness of the state’s geologic resources. The IGS also provides geologic information through interactive online maps on its website.
“I strongly advocate the importance of [IGS] outreach to the public and hope it continues for future generations.”

For 125 years, the Iowa Geological Survey (IGS) has been addressing the natural resource, environmental, and groundwater needs of Iowans.
IGS geoscientists focus on what’s beneath the Earth’s surface. These resources, though often out of sight, are essential to lives and livelihoods.
The IGS has expertise in Iowa’s earth and mineral resources, groundwater, geologic hazards, and more.
IGS staff provide important services to Iowans, supporting jobs and industries, a safe and sustainable environment, and even individual health.
What does the IGS do for Iowans?
The Iowa Geological Survey Serving Iowans for our Economy, Environment, & Quality of Life
