A drastic increase in environmental pollution across the globe has led to various research and development works in an effort to contain this menace and a relatively new discipline called environmental engineering has emerged which is providing excellent career opportunities. Environmental Engineering is the integration of sciences and engineering principles to improve the natural environment, to provide healthy water, air, and land for human habitation and for other organisms, and to clean up pollution sites. Environmental engineering can also be described as a branch of applied science and technology that addresses the issue of energy preservation, production asset and control of waste from human and animal activities. Furthermore, it is concerned with finding plausible solutions in the field of public health, such as waterborne diseases, implementing laws which promote adequate sanitation in urban, rural and recreational areas. 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 apply combined methods of science and engineering to improve the environment so that people have access to healthy water, air and land suitable for human existence. Overtime, opportunities in environmental engineering have increased in last couple of decades and the professionals are recruited by companies working in chemical, geological, petroleum and mining sectors.
