matter are made useful to mankind in the form of structures, machines, and other products or processes at a reasonable cost
of money and time. An engineer is a person trained or skilled in designing and planning the performance of such equipment
as machines and structures and in supervising their performance.
An Environmental (or sanitary) Engineer is concerned with the water and sewage treatment as well as the resi-
dential and industrial wastes. Environmental engineers are trained in preventing, evaluating, and solving environmental
problems. To be successful, environmental engineers must combine technical knowledge with effective communication
skills in day-to-day work and be able to communicate effictively with people of all types if they are to succeed in solving all
of the problems facing them. The protection of rivers and lakes is part of their responsibility. In this profession, a know-
ledge of chemistry and biology must be added to the engineering base. There are many different jobs that the enviorn-
mental engineers have to do. First, there is Water Quality. Protecting the quality of water required for human use and
environmental protection is an important role for environmental engineers. Increasingly severe quality standards for drink-
ing water, wastewater, pollutant, and groundwater require engineers and scientists trained in the theory and practice of
water and wastewater treatment. In addition, environmental engineers must be able to predict the fate of contaminants in
multimedia enironments in order to measure the effects of pollution on humans and ecosystems. Water quality engineering
involves the application of environmental chemistry, microbiology and physics together with modeling and process engin-
eering to address these areas.
Second, there is Hazardous Waste Management. Many industrial societies produce and dispose of significant
amounts of hazardous materials. In sufficient treatment, storage and disposal have resulted in many uncontrolled contami-
nant releases to the environment. Innovative engineering solutions are needed for liquid, gaseous and solid hazardous waste
streams as well as for contaminated site remediation. It is the job of environmental engineers to understand and solve
these waste problems.
Third, there is Air Quality. Air pollution is a big problem in society today. Environmental engineers solve air pol-
lution problems across a range of scales, with particular focus on indoor environments and urban air basins. They also have
to understand the physical and chemical processes that determine the concentrations, fates, and effects of air pollutants; they
also consider the social context in which engineered solutions must be developed. Environmental engineers also have to
study water and land because air pollution problems cannot be solved without considering impacts on water and land. To
effectively mark resources for the protection of public health and the environment, and to develop effective waste treatment
systems, environmental engineers are often asked to predict the fate and transport of pollutants in air, water, sediments, and
Last, is Contaminants prediction. To effectively dedicate resources for the protection of public health and the en-
vironment, and to develop effective waste treatment systems, engineers often are asked to predict the destiny and transport
of pollutants in air, water, sediments and soil. Emphasis is placed on the prediction of a pollutants destiny, and transport in
natural systems and the development of concepts that can be used in the design of innovative treatment systems.
