Environmental Engineering
The division of engineering concerned with the environment and management of natural resources. The environmental engineer places special attention on the biological, chemical, and physical reactions in the air, land, and water environments and on improved technology for integrated management systems, including reuse, recycling, and recovery measures.
Environmental Engineering
How did it began?
Definition: (ASCE) Environmental Engineering
...the proper disposal or recycle of wastewater and solid wastes; the adequate drainage of urban and rural areas for proper sanitation; and the control of water, soil and atmospheric pollution, and the social and environmental impact of these solutions.
Pollution
• • • • • • Air Water Land/Soil Noise pollution Thermal pollution Radiation pollution
Furthermore, It is concerned with engineering problems in the field of public health, such as control of arthropodborn diseases, the elimination of industrial health hazards, and the provision of adequate sanitation in both urban, rural and recreational areas, and the effect of technological advancement on the environment. (1977)

Operational terms in the definitions of Pollution
• The unnatural presence of a poison or hazardous material • …not naturally-occurring • Man-made (anthropogenic) • …changes the natural environment • Impairs the environment in performing its intended task • Leads to the destruction of the ability of the environment to perform its intended function in the future.
Conservation vs. Protection
• Two very different schools of thought • “Protection” was aimed towards the absolute nondisturbance/non-use of the environment • Conservation became acceptable when we realized that the human population was part of the ecological balance and that our survival depended heavily on our ability to maintain this
