Environmental Engineering (MS) 
Program Description

The Environmental Engineering Program is one of the top ranked graduate engineering programs at UA, and highly ranked nationally. The program has long-standing strengths in water and wastewater treatment science and technology as well as technology transfer, hazardous waste treatment, development of environmentally-friendly technologies for industry, and atmospheric research. Owing to the multidisciplinary strengths of Environmental Engineering, students participate in research collaborations with numerous other programs such as Chemical Engineering, Hydrology and Atmospheric Sciences, Civil Engineering, Mining and Geological Engineering, and Environmental Science.

This department’s environmental research contributes to the UA being one of the top ranked world programs in environmental science research.

Departmental research takes advantage of state-of-the-art facilities such as the Water & Energy Sustainable Technology (WEST) Center (, the BIO5 Institute (, the Micro/Nano Fabrication Center (, and various facilities associated with the Institute for Energy Solutions (

Students in this program have a good track record of receiving financial aid from both university and federal fellowships. Environmental Engineering is a rapidly-growing field with promising job prospects in public and private sectors. Graduates of this program most commonly obtain jobs in industry, government organizations, consulting, and continue on to advanced education to enter academia.
