The responsibilities of an environmental geologist include evaluating and analyzing data related to groundwater, soil, and the mineral and geological components of industrial operations. This involves conducting field investigations to collect samples of site contaminants and analyzing their composition in the lab. Based on their research, environmental geologists develop assessments of contamination and implement strategies to manage or remove pollution in the soil or groundwater. This role requires a balance of fieldwork and laboratory analysis to address environmental concerns and protect natural resources.
