Environmental engineering encompasses the scientific assessment and development of engineering solutions to environmental problems affecting land, water, and air (the biosphere). The field embraces broad environmental concerns, including the safety of drinking water, groundwater protection and remediation, wastewater treatment, indoor and outdoor air pollution, solid and hazardous waste disposal, cleanup of contaminated sites, the prevention of pollution through product and process design, and strategies for sustainable water and energy use and production.
Environmental engineers must balance competing technical, social, and legal issues concerning the use of environmental resources. Because of the complexity of these challenges, environmental engineers need a broad understanding not only of engineering disciplines but also of chemistry, biology, geology, and economics. Accordingly, the program allows students in the major to select an emphasis on environmental engineering technology, sustainability, global health, economics, or energy and climate change. The program prepares students for leadership positions in industry and government agencies or for further studies in engineering, science, business, law, and medicine.
Two degree programs are offered: the B.S. in Environmental Engineering, and the B.A. in Engineering Sciences (Environmental). The B.S. degree program in Environmental Engineering is designed for students who desire a strong background in environmental engineering leading to a career in the field. The B.A. degree program in Engineering Sciences (Environmental) is intended for students whose careers will involve, but not be dominated by, the skills of environmental engineering. The B.A. program is appropriate for those contemplating a career in which scientific and technological problems can play an important role, as is often the case in law, business, medicine, or public service.
B.S. degree program in Environmental Engineering The B.S. degree program has the following prerequisites in mathematics and basic sciences: MATH 112, 115; MATH 120 or ENAS 151; ENAS 194; a two-term lecture sequence in chemistry, with corresponding labs; PHYS 180, 181; and BIOL 101 and 102 or 103 and 104.
Requirements of the Major
B.A. degree program The B.A. degree program requires nine term courses beyond the prerequisites, including the senior requirement. Students take ENVE 120, 360, and either 373 or 377. Five electives must be chosen in consultation with the DUS.
B.S. degree program The B.S. degree program requires at least twelve term courses beyond the prerequisites, including the senior requirement. Students take CENG 300 or MENG 211, ENVE 120, 360, 373, 377, and either 315 or 448, EVST 344, and MENG 361 or F&ES 714. At least three electives must be chosen in consultation with the DUS, preferably within one of the following tracks: environmental engineering technology, sustainability, global health, economics, or energy and climate change.
Credit/D/Fail No course taken Credit/D/Fail may count toward the major, including prerequisites.

Environmental engineers are involved with many aspects of society’s interaction with the environment. The field embraces broad environmental concerns, including the safety of drinking water, groundwater protection and remediation, wastewater treatment, indoor and outdoor air pollution, solid and hazardous waste disposal, cleanup of contaminated sites, preservation of sensitive wetlands, energy and the environment, and prevention of pollution through product and process design. Environmental engineers must balance technical, social, economic, and legal issues concerning the use of environmental resources. Consequently, they need a broad understanding not only of engineering disciplines but also of chemistry, biology, geology, economics, and management.
Students majoring in Environmental Engineering select an emphasis on environmental engineering technology, sustainability, global health, energy and climate change, or economics. The major prepares students for leadership positions in industry and government agencies. Graduates may also continue with further studies in engineering, science, business, law, and medicine.
Students interested in the major should take the following course during the first year:
- ENVE 120 , Introduction to Environmental Engineering
One of the following math courses:
- MATH 112 , Calculus of Functions of One Variable I
- MATH 115 , Calculus of Functions of One Variable II
- MATH 120 , Calculus of Functions of Several Variables
One of the following chemistry sequences:
- CHEM 161 , General Chemistry I and CHEM 165 , General Chemistry II
- CHEM 163 /167 , Comprehensive University Chemistry I and II
There will be a meeting in the fall for students interested in the major; details will be published in the Calendar for the Opening Days. Additional information can be found on the Chemical and Environmental Engineering Website. The director of undergraduate studies (DUS) welcomes consultation with students about the program at any time.
