The rapid industrial growth in Northeastern Indiana has lead to the demand for more complete geologic information for Steuben County, Indiana by the citizenry. The information would allow environmental scientists, geologists and engineers to more accurately predict the potential migration and impact of pollutants on the soil and groundwater. As part of ongoing environmental site investigations in Steuben County, well data were collected from Indiana Department of Environmental management (IDEM) and the State of Indiana Department of Natural Resources to determine local and regional groundwater flow directions. Of the 162 registered wells in the study area, only 67 of them, that is, 41% of the data could be used. The remaining well data could not be used because of poor, inaccurate or incomplete information on the forms (i.e., location description, well log, elevation, etc.). The regional groundwater flow direction was northwest as would be expected from the topography. A groundwater divide or ridge that was implied from the local groundwater flow directions could not be confirmed due to poor well data. The determination of groundwater flow direction was made more complicated due to incomplete well logs from drillers. Increased industrial activities in the region could lead to greater potential for surface and groundwater pollution problems. It is recommended that well data be collected by qualified personnel (field geologists) during well drilling.
