The Departments of Civil Engineering, Biological Systems Engineering, and Chemical Engineering jointly administer an interdisciplinary program leading to a Master of Science in environmental engineering. The program is closely coupled to other areas, particularly in the water environment and natural resources areas. Faculty members in the three departments offer a balance of expertise covering the four major areas of environmental engineering, as sanctioned by the American Academy of Environmental Engineers. These include: water supply engineering, wastewater engineering, hazardous waste management engineering, and solid waste management engineering. A fifth area of emphasis in diffuse (nonpoint) and agricultural waste management engineering is also available.
