GEOSAM contains information about water wells, their construction design and geologic framework, along with other geological sites from around Iowa. The long-term systematic collection and retention of earth science data continues to be of immeasurable value to the State of Iowa. Refinements in data collection and interpretation have evolved with improved technology, and these refinements have permitted improved capabilities in problem-solving and service functions for the Iowa Geological Survey to the general public. Access to this data is instrumental in the production of most of the Survey's geologic and hydrologic maps, reports, and responses to information requests. Now that this information has been made available to everyone via the internet, drillers, consultants, engineers, etc. can utilize this information to aid in estimating the depth, well construction concepts, and water yield of specific aquifers and other site specific design needs.
