The environmental engineering program includes studying subjects in sciences such as chemistry, physics, biology, mathematics, and basic engineering, in addition to subjects in chemical engineering, fluids, hydraulics, thermodynamics, unit operations, all types of water treatment and wastewater, as well as materials engineering, soil engineering, erosion, and geology.

The study of environmental engineering, its scope of work, and its needs will continue as long as the environment exists, humans and living organisms live in it, and environmental changes continue. In addition, the more scientific and technological progress continues, the wider the circle of environmental problems and pollution and the more urgent the need to address them. It has been observed from the reality of technological progress that in the event of new environmental problems, these problems will be created by human-led technological advances on Earth.

Environmental problems include pollution. Whenever pollution occurs, it results in an environmental problem that needs addressing. And pollution means the presence of factors that cause the change of environmental characteristics and its departure from the natural qualities created by Allah - Exalted and Glorified by He - to achieve the healthy life of man. For example, if water or air is mixed with chemical or biological substances that change the characteristics of water and air, they become unfit for life, which causes diseases and death in some cases.

The goal is always to have a clean life and clean production and to try as much as possible to prevent pollution. This is achieved by having sound management in our institutions working to prevent pollution before it occurs. In the event of pollution, there is a need to create a sound program that includes an appropriate plan for dealing with pollution. That requires sequential steps, such as the handling and transport process, industrial recycling process, extraction of new materials and energy process, landfill operations in special pits and processing through analysis and monitoring procedures and appropriate unit operations.

A branch of engineering concerned with studying and treating all types of pollution impacting the environment and life, such as the pollution of water, air, and soil. It also includes noise pollution and other sources of pollution.

Environmental engineering includes the basic environmental sciences, in addition to the basic engineering sciences, and engineering sciences specialized in solving the environmental problems resulting from pollution and conducting the treatment process via analysis and unit operation and design. The environmental sciences are limited to studying the diverse environmental problems and pollution and its types, sources, and impact on life.

In each place where an environmental impact occurs, such as change, pollution, and risk to wildlife, we find application fields of environmental engineering to address the environmental impact. That is why we find environmental engineering applications in industry, agriculture, mines, oil fields, and geological fossils, in addition to air, seas, and other sources of water. That is to be added to governmental establishments, including civil and military institutions, cities, and rural areas.

Environmental engineering includes sciences derived from environmental sciences, biology, and the engineering sciences, particularly chemical engineering, which covers processes and units of treatment besides civil engineering, which covers the organization of cities and districts, the distribution of drinking water, channels and discharging of sewage outside the boarders of the city, collecting and managing solid waste, and processing and recycling it.
