Environmental Engineering is the integration of science and engineering principles to improve the natural environment, to provide healthy water, air, and environments for habitation of many types of organisms, and to remediate pollution sites. It involves waste water management and air pollution control, recycling, waste disposal, radiation protection, industrial hygiene, environmental sustainability, and public health issues as well as a knowledge of environmental engineering law. It also includes studies on the environmental impact of proposed construction projects.
Environmental engineers study the effect of technological advances on the environment. To do so, they conduct hazardous-waste management studies to evaluate the significance of such hazards, advise on treatment and containment, and develop regulations to prevent mishaps. Environmental engineers also design water supply and industrial wastewater treatment systems, life support systems, temperature controllers, and atmosphere processors.
