This ABET supporting course introduces cadets to the study of environmental engineering from a unit process and a materials balance approach. The focus is design-oriented problem solving to protect human health and the health of ecosystems using fundamental physical, chemical, and biological processes. The concept and calculation of risk is introduced as a key factor in environmental decision-making. Through the study of contaminant removal from water and air to integrated management techniques for solid/hazardous wastes and ionizing radiation, cadets are exposed to the breadth of the discipline. In the laboratory the science behind physical, chemical, and biological processes are applied to the engineering discipline. A course design problem allows application of engineered solutions to timely water and air quality issues.
