Issue: The issue of water-resources planning is coming to the forefront in Indiana. Early reconnaissance studies have indicated that incomplete or inaccurate databases might inhibit studies that rely on those data. Therefore, examination of existing databases and creation of new, targeted, and relevant databases related to water resources are needed in Indiana.
Objective: This project will support the larger effort of improving the data accuracy in databases important to water resources planning in Indiana.
Approach: Accurate locations will be collected for approximately 9000 wells and intakes at facilities registered with IDNR. This will be accomplished by a combination of in-office location verification using GIS software, self-reported locations via a survey sent to registrants, and a field location program.
Products: Maps and tables, accompanied by a report outlining the results of the locational error assessment.
Benefits: In addition to having an assessment of the accuracy of water utility location information in Indiana, this study will also serve as a demonstration of the capabilities of the Center for Geospatial Data Analysis, Indiana Geological Survey for large-scale studies, and poise us for additional studies in the future.
