Environmental engineers strive to solve environmental problems such as water and air pollution, waste disposal, and public health issues. As engineers, they use advanced principles of biology, chemistry, and environmental science to protect wildlife and natural resources as well as human life. Environmental engineers are qualified to work on a variety of serious environmental issues. For example, they can design municipal water supply and industrial wastewater treatment systems; assess recycling and reclamation processes; conduct hazardous waste management studies; and consult on the environmental effects of various construction projects. They may be required to inspect and evaluate industrial and municipal facilities and programs to assess their compliance with environmental regulations. They may work with environmental scientists, planners, hazardous waste technicians, engineers, and other specialists to address environmental problems.
