The Department of Civil and Environmental Engineering and the Environmental Engineering and Science Program are pleased to acknowledge the contributions that we have received from many alumni and friends. Resources provided by these gifts support graduate student fellowships, graduate student travel to professional conferences, our very successful Graduate Student Spring Symposium, a professorship, special seminars that invite distinguished professionals to our department, large equipment purchases, extensive laboratory renovations, student writing competitions, and other educational activities. Such support allows us to maintain our high quality program and continue to attract and educate some of the best environmental engineering students in the world. Our quality has been recognized by U.S. News and World Report with consistent rankings of our program as one of the best in the country, with a recent ranking at #3.  Students in our program recognize these contributions as one of the key reasons why we are able to offer high quality and high profile educational experiences during their studies at the University of Illinois.
