Environmental engineering is a study of science and engineering principles to improve the environment, to provide healthy water, air and land for humans and other organisms, and to remediate polluted 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 knowledge about environmental engineering law.
Scope of Environmental Engineering:
The main task of environmental engineers is to protect public health by protecting, preserving, and enhancing the environment. Also, they develop new forms of energy and ways to increase the efficiency of generating and using energy. They try to convert the people to an environmental friendly energy and products.
There are various categories of the field in environmental engineering.
Environmental impact assessment and mitigation:
A systematic approach and evaluation process to assess the potential impacts of a proposed project, plans, programs, policies, or legislative actions upon the physical-chemical, biological, cultural, and socioeconomic components on environmental conditions.
Water supply and treatment:
Engineers and scientists work to secure water supplies for potable and agricultural use. Water is treated to achieve water quality objectives for the end uses. In the case of potable water supply, water is treated to minimize the risk of infectious disease transmission, the risk of non-infectious illness, and to create a palatable water flavor.
Wastewater conveyance and treatment:
Engineers and scientists have developed the collection and treatment systems to carry this waste material away from where people live and produce the waste and discharge it into the environment. Developing nations are striving to obtain the resources to develop such systems so that they can improve water quality in their surface waters and reduce the risk of water-borne infectious disease.
Air quality management:
Engineers imply scientific and engineering principles to the design of manufacturing and combustion processes to reduce air pollutant emissions to acceptable levels. Scientists developed many air pollution dispersion models to evaluate the concentration of a pollutant at a receptor or the impact on overall air quality from vehicle exhausts and industrial flue gas stack emissions.
