The state of the environment has only become worse within the last few decades. Pollution of all kinds, deforestation that destroys the natural habitats of animals and thus endangers them are only a few instances of how the ecological balance is being disrupted. So what is environmental engineering? It mainly deals with environment based subjects like pollution control, industrial hygiene, hazardous waste management, radiation protection, toxic materials control, waste disposal and water supply related problems. The eligibility criteria for doing a Bachelor of Technology (B.Tech.) in Environmental Engineering is generally that you should pass the higher secondary exam from a board that is recognized in India with physics, chemistry and mathematics with at least fifty percent in aggregate. Competitive engineering exams such as the Joint Entrance Exam (JEE) or Birla Institute of Technology and Science Admission Test (BITSAT) have to be cleared as well by those who seek admission. Graduates in this course can find work in the Central and State Pollution Control Boards, in distilleries, water treatment industries, food processing industries, in state forest departments, Department of Agriculture and Cooperation, state water authorities and urban departments. They might also find work in research institutes as technical assistants, project assistants or research associates.
