Industrial Engineering

Bachelor of Science in Environmental Engineering

The Environmental Engineering Program leads to the B.S. Degree in Environmental Engineering. The program offers basic knowledge in environmental engineering subjects that will allow students to understand and subsequently acquire additional knowledge in their specialized fields of interest, according to personal inclination and available opportunities. Courses are offered, among others, in the fields of water supply engineering, wastewater engineering, groundwater pollution and control, air pollution and control, solid waste and resource recovery engineering, hazardous waste management, occupational safety and health, environmental impact assessment, environmental toxicology, and pollution prevention engineering. Elective courses in the specialization component are offered. The students are encouraged to select their elective courses so that they best fit their interests, abilities and career opportunities.

Modern engineering is one of the great pillars of economic and social development. But development must not occur at the expense of environmental degradation. Therefore, the engineering design of urban, agricultural and industrial facilities must have environmental protection mechanisms or systems built in. The environmental engineer is the professional who is academically prepared to design these environmental protection mechanisms and systems; and to collaborate with other professionals in the creation of environmentally sound engineering works. Graduates from this program will have their place in government agencies with regulatory, construction or maintenance responsibilities; in design and consulting engineering firms; and in the industrial sector, especially in the type of industry that, because of its industrial operations, results in significant environmental impact. On the other hand, Environmental Engineering bachelors will be much better prepared to pursue successfully graduate degrees in this field if they so desire.
