Although Iowa has abundant water supplies in general, recent demands for the state’s limited groundwater resources
Growing urban areas, ethanol production, large-scale livestock feeding operations, and industry are pumping groundwater out of the aquifer faster than it can recharge in some parts of Iowa.
IGS hydrologists have decades of experience using predictive models for potential research related to drought resiliency, aquifer storage and recovery, water sustainability, and nitrate. IGS researchers have developed groundwater flow models for four of Iowa’s regional bedrock aquifers. These regional numerical models allow researchers to forecast the future impact of changes in water usage and infrastructure.
