Partnering with the Iowa Department of Natural Resources IGS WORKS COLLABORATIVELY with the Iowa Department of Natural Resources (IDNR) on many issues related to Iowa’s water and natural resources. The organizations share data and expertise across several different platforms, with information related to well records, geologic samples, pump test data, and other geospatial data. During the 2019–20 fiscal year, IGS provided IDNR the following services: • Keith Schilling assisted the DNR by leading a New Year’s Day “First Day Hike” at Cedar Rock State Park. • Updated GeoSam with records from over 2,600 wells. Twenty-two of the records were specifically for the DNR’s Water Use and Public Water Supply program well. Eighty-four were specifically for the DNR’s Animal Feeding Operation program. • Provided lithologic strip logs for one well and part of another, totaling 1,385 feet. • Analyzed and entered 23 pump tests to IGS PumpTest database for DNR to access. • Evaluated shallow groundwater levels on a monthly basis for inclusion in the DNR’s Drought Summary update. • Provided technical assistance on a geophysical investigation of the Amana wellfield to the DNR’s Water Supply group. • Updated the statewide Cambrian-Ordovician groundwater flow model to local conditions found in the Des Moines Metropolitan Area.
