Environmental and Ecological engineers apply technical understanding of environmental systems, systems engineering, biology, and chemistry to develop strategies to protect human and environmental health, and design sustainable systems and technologies. They can address issues at the local or global level, such as unsafe drinking water, air quality, and industrial sustainability. Projects may focus on improvement of materials cycling, resource recovery, public health, and water and air pollution control.<br><br>Environmental and Ecological Engineering (EEE) at Purdue is unique and cutting edge in that it educates students in a systems perspective that includes sustainability as it applies to natural and industrial processes. Rather than only considering conventional waste emission treatment, we train our students to approach problems from an integrated perspective that considers both environmental issues and ecological aspects. Our name highlights this modern approach of EEE relative to similar programs at peer institutions.
