Groundwater studies include flow systems, aquifer capacity, groundwater chemistry, and sensitivity to pollution. In some areas sand and gravel deposits, sinkholes, or other features are studied.GIS layers convey geologic and hydrogeologic information and interpretations to governmental units, businesses, and the general public. The information is used in planning and environmental protection efforts and to provide information for permit applications and plans and emergency response to contaminant releases.publication dates range from 1996 to present with the time period of the content ranging from 1995 to presentFilesgeos-geologic-atlas-part-bengPublicCounty Geologic Atlas, Part B [Minnesota]OtherMinnesotaMinnesota Geospatial Commons
