IGS - Geology and Groundwater Studies

Geology and Groundwater Studies Section

This section analyzes all parameters of geologic and hydrogeologic conditions, water resources budget relationships between supply and demand, economic mineral resources, geologic hazards, and defines the extent, recurrence interval, and impact of local and/or regional water development. Comprehensive data collection and investigative programs are developed and implemented to enhance the state's geologic and water resources databases. Site specific and areal information services are provided to well contractors, engineering firms, municipalities, and the private sector for water supply development and management, mineral extraction, construction projects, and other aspects of resource management . Data review and interpretation are provided to DNR's Environmental Services Division to assist in regulatory decisions relative to water withdrawal permits, well-interference problems, waste disposal sites, and other permitted facilities.  Research and applied studies are planned and implemented to investigate and monitor water quality degradation related to agricultural and industrial chemicals, leaking underground tanks, sanitary landfills, and waste-water lagoons.
