As a civil engineering major, you can add an environmental engineering concentration to your major and prepare for a career in this fast-growing engineering discipline. Take specialized courses in ecology, water and wastewater treatment, environmental systems, environmental ethics and more. Work side-by-side with an ONU engineering professor on environmental-related research. Engage in a summer research experience at a national lab for the Environmental Protection Agency or the National Park Service. You might even land a co-op or internship at one of the biggest players in the environmental industry, like CH2M, AECOM, or Hull & Associates, which may lead to an offer of full-time employment.
