Earth Science uses an integrated approach to the study of the problems of the earth environment through a synthesis of geology, hydrology, and geochemistry. The B.S. program emphasizes a foundation in geology with a focus on environmental geosciences.

Strong emphasis is placed on experimental and field studies across the curriculum. Internship opportunities are available for advanced students. An independent study option exists for students who wish to complete individualized research under the direction of a faculty member.

Curricula are individually planned to provide a broad basic training in earth science and, more specifically, to prepare students for further graduate study or for careers in the hydrogeological, geotechnical, and environmental fields, as well as areas related to geologic resources, soils, and other careers related to environmental geosciences. Programs have the flexibility to meet individual student needs for career preparation or for graduate studies.

Areas of concentration of coursework represent an emphasis in environmental geology, including mineralogy-petrology and mineral resources, hydrogeology, soil science and geotechnical areas, and lake systems. Techniques of problem-solving in geology and environmental geoscience are emphasized.

Facilities and available equipment include instrumentation for water quality analysis, a prismless total station, apparatus for X-ray diffraction analysis, ground water flow models, hydrogeological laboratory and testing equipment, field equipment for water and soil sampling, equipment for rock and thin section preparation, and mineral separation. Also available are sedimentation tanks, centrifuge and size analysis apparatus, atomic absorption spectrophotometer, optical microscopy with image analysis capabilities, a student computer lab, a teaching seismograph, and facilities for petrographic, hydrogeologic, and aqueous geochemical analysis. The program maintains three monitoring wells on campus for student practice in hydrologic testing.

Earth Science offers a program leading to a degree of Bachelor of Science. An undergraduate minor is also available.

ESCI-109. First Year Experience:Chicago Rocks! Geology In The City. 3 Hours.

Chicago has been at the bottom of the sea, buried under a mile of ice, and set in a warm, tropical paradise. Such diverse changes have shaped Chicago and the surrounding region, including the lake, the rivers, the ground we walk on (and build on), and the decisions we make about land use, resources, and waste management. Explore Chicago Rocks - as well as water, weather, and land forms - in the context of current issues related to resource use and the environment. Field trips and hands-on experiences highlight the extent to which geology influences the character of the Chicago area.
