Geology, also known as geoscience or earth science, is the study of the Earth — how it was formed, its structure and composition, and the processes that shape that structure. Integrated earth resource evaluation that incorporates sustainable economic vitality and environmental and public health protection is accomplished through geologic mapping and investigations, groundwater protection, energy and mineral resource characterization, identification and response to geologic hazards, and by providing geologic information and online services. 

Our team members investigate the state’s geology, providing geologic and hydrologic information and expertise to aid economic development, infrastructure considerations, and environmental decision-making regarding site remediation, contaminant migration, subsurface investigations, and geologic hazards. 

We oversee the proper construction of all wells, including water, oil, gas, exploration, heat pumps and monitoring. Team members determine the character and availability of the state’s energy and mineral resources. 

Land reclamation duties include developing regulations, permitting, inspection, complaint investigation, bonding and enforcement, as well as human health and environmental hazard assessment, reclamation plan designs, contracting, budgeting, public relations, landowner education, construction oversight, and maintenance of reclaimed abandoned mine lands.
