Environmental impact assessment Scientists have 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. To some extent, this field overlaps the desire to decrease carbon dioxide and other greenhouse gas emissions from combustion processes.
They apply scientific and engineering principles to evaluate if there are likely to be any adverse impacts to water quality, air quality, habitat quality, flora and faunaagricultural capacity, traffic impacts, social impacts, ecological impacts, noise impacts, visual landscape impacts, etc.
If impacts are expected, they then develop mitigation measures to limit or prevent such impacts. An example of a mitigation measure would be the creation of wetlands in a nearby location to mitigate the filling in of wetlands necessary for a road development if it is not possible to reroute the road.

Since that time, more than developing and developed nations either have planned specific analogous laws or have adopted procedure used elsewhere. Water is treated to achieve water quality objectives for the end uses. In the case of a 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.
Water distribution systems are designed and built to provide adequate water pressure and flow rates to meet various end-user needs such as domestic use, fire suppression, and irrigation.
Wastewater treatment[ edit ] Water pollution There are numerous wastewater treatment technologies. A wastewater treatment train can consist of a primary clarifier system to remove solid and floating materials, a secondary treatment system consisting of an aeration basin followed by flocculation and sedimentation or an activated sludge system and a secondary clarifier, a tertiary biological nitrogen removal system, and a final disinfection process.
The secondary clarifier removes the activated sludge from the water.
The tertiary system, although not always included due to costs, is becoming more prevalent to remove nitrogen and phosphorus and to disinfect the water before discharge to a surface water stream or ocean outfall. Environmental Protection Agency[ edit ] The U.

Environmental Protection Agency EPA is one of the many agencies that work with environmental engineers to solve key issues. An important component of EPA's mission is to protect and improve air, water, and overall environmental quality in order to avoid or mitigate the consequences of harmful effects.
Ecological engineering for sustainable agriculture in arid and semiarid West African regions  [ edit ] Ecological engineering offers new alternatives for the management of agricultural systems that are more tailored to the ever-changing social and environmental necessities in these regions.
This requires managing the complexity of agrosystems, while striving to mimic the functioning of natural ecosystems of West African drylands and taking advantage of traditional practices and local know-how resulting from a long process of adaptation to environmental constraints. Biodiversity is essential to the productivity of ecosystems and their temporal stability under the impact of external disturbances.
Several ecological processes related to biodiversity may be intensified for the benefit of agrosilvopastoral systems: The productivity of agrosystems with low chemical input use in dryland regions is primarily based on efficient organic resource management, and in turn on the nutrient and energy flows they induce.
It is thus possible to intervene at several levels: Enhancing available water use.
Water supplies are limited and irregular in dryland areas. Current management of these supplies—which involves capturing rainwater and surface runoff—could be improved in several ways: Managing landscapes and associated ecological processes.
Ecological crop pest regulation by their natural enemies is one ecosystem service provided by biodiversity. Better pest management could be considered in association with promoting biodiversity at different scales, e.
Education[ edit ] Courses aimed at developing graduates with specific skills in environmental systems or environmental technology are becoming more common and fall into broad classes: Mechanical engineering courses oriented towards designing machines and mechanical systems for environmental use such as water treatment facilities, pumping stations, garbage segregation plants and other mechanical facilities; Environmental engineering or environmental systems courses oriented towards a civil engineering approach in which structures and the landscape are constructed to blend with or protect the environment; Environmental chemistrysustainable chemistry or environmental chemical engineering courses oriented towards understanding the effects good and bad of chemicals in the environment.
Focus on mining processes, pollutants and commonly also cover biochemical processes; Environmental technology courses oriented towards producing electronic or electrical graduates capable of developing devices and artifacts able to monitor, measure, model and control environmental impact, including monitoring and managing energy generation from renewable sources.

A number of solutions have been proposed to mitigate the potential harm of a nuclear winter if one appears inevitable; with the problem being attacked at both ends, from those focusing on preventing the growth of fires and therefore limiting the amount of smoke that reaches the stratosphere in the first place, and those focusing on food.
There is concern about the "Final Keport of the Study Group on Mission and Organization of the Public Health Service," dated June 7, , which recommends inclusion of the water pollution control functions in a Division of Water Supply and Pollution in a new Bureau of Environmental Health.

Environmental engineering is the branch of engineering concerned with the application of scientific and engineering principles for protection of human populations from the effects of adverse environmental factors; protection of environments, both local and global, from potentially deleterious effects of natural and human activities; and improvement of environmental quality.
