Environmental engineering is the application of science and engineering principles to improve the environment to provide healthy water, air and land for human habitation and for other organisms, and to remediate polluted sites. Environmental engineering involves water and air pollution control, recycling, waste disposal and public health issues as well as knowledge of environmental engineering law. It also includes studies on the environmental impact of proposed construction projects.
Environmental engineering is the planning, design, construction, operation and maintenance of constructed facilities for the protection of human health and safety and the preservation of wildlife and the environment. It includes water supply and resources, modelling of environmental systems, environmental chemistry, wastewater management, solid waste management, hazardous-waste management and remediation, atmospheric systems and air pollution control and environmental and occupational health.
Environmental engineers conduct hazardous-waste management studies to evaluate the significance of any hazards, advise on treatment and containment and develop regulations to prevent mishaps. Environmental engineers also design municipal water supply and industrial wastewater treatment systems and are also concerned with local and worldwide environmental issues such as the effects of acid rain, ozone depletion and water and air pollution from automobile exhausts and industrial sources.
At many universities, environmental engineering programmes are offered by either the Department of Civil Engineering or the Department of Chemical Engineering. Environmental civil engineers focus on hydrology, water resources management and water treatment plant design. Environmental chemical engineers, on the other hand, focus on environmental chemistry, advanced air and water treatment technologies and separation processes.
