Environmental engineering Wikipedia. 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. Environmental engineering can also be described as a branch of applied science and technology that addresses the issues of energy preservation, protection of assets and control of waste from human and animal activities. Furthermore, it is concerned with finding plausible solutions in the field of public health, such as waterborne diseases, implementing laws which promote adequate sanitation in urban, rural and recreational areas. It involves waste water management, air pollution control, recycling, waste disposal, radiation protection, industrial hygiene, animal agriculture, environmental sustainability, public health and environmental engineering law. It also includes studies on the environmental impact of proposed construction projects. Environmental engineers study the effect of technological advances on the environment. To do so, they conduct studies on hazardous waste management to evaluate the significance of such hazards, advise on treatment and containment, and develop regulations to prevent mishaps.

Lancasters Engineering Department is internationally recognised as being at the forefront of research and innovation. Conducts research and development programs in environmental science and technology. Environmental engineers design municipal water supply and industrial wastewater treatment systems. They address local and worldwide environmental issues such as the effects of acid rain, global warming, ozone depletion, water pollution and air pollution from automobile exhausts and industrial sources. At many universities environmental engineering programs are offered at either the department of civil engineering or the department of chemical engineering at engineering faculties. Environmental civil engineers focus on hydrology, water resources management, bioremediation, 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. Additionally, engineers are more frequently obtaining specialized training in law J. D. and are utilizing their technical expertise in the practices of environmental engineering law. Most jurisdictions also impose licensing and registration requirements. DevelopmenteditEver since people first recognized that their health is related to the quality of their environment, they have applied principles to attempt to improve the quality of their environment. The ancient Indian Harappan civilization utilized early sewers in some cities more than 5.

While our foundation has held firm, we pride ourselves on continuing to modernize the curriculum and our teaching practices. The prestigious 2016 Bernard M. Gordon. The Romans constructed aqueducts to prevent drought and to create a clean, healthful water supply for the metropolis of Rome. In the 1. 5th century, Bavaria created laws restricting the development and degradation of alpine country that constituted the regions water supply. The field emerged as a separate environmental discipline during the middle third of the 2. However, its roots extend back to early efforts in public health engineering. Modern environmental engineering began in London in the mid 1. Joseph Bazalgette designed the first major sewerage system that reduced the incidence of waterborne diseases such as cholera. The introduction of drinking water treatment and sewage treatment in industrialized countries reduced waterborne diseases from leading causes of death to rarities. In many cases, as societies grew, actions that were intended to achieve benefits for those societies had longer term impacts which reduced other environmental qualities.

While the agricultural benefits were outstanding and crop yields increased dramatically thus reducing world hunger substantially, and malaria was controlled better than it ever had been, numerous species were brought to the verge of extinction due to the impact of the DDT on their reproductive cycles. The story of DDT as vividly told in Rachel Carsons Silent Spring 1. Conservation movements and laws restricting public actions that would harm the environment have been developed by various societies for millennia. Notable examples are the laws decreeing the construction of sewers in London and Paris in the 1. U. S. national park system in the early 2. Solid waste managementeditEnvironmental impact assessment and mitigationeditScientists 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 fauna, agricultural 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. In the United States, the practice of environmental assessment was formally initiated on January 1, 1. National Environmental Policy Act NEPA. Since that time, more than 1. NEPA is applicable to all federal agencies in the United States. Water supply and treatmenteditThey evaluate the water balance within a watershed and determine the available water supply, the water needed for various needs in that watershed, the seasonal cycles of water movement through the watershed and they develop systems to store, treat, and convey water for various uses. 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 treatmenteditThere 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 aeration basinactivated sludge system removes organic material by growing bacteria activated sludge. 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.
