Introduction Environmental engineering is the development of processes and infrastructure for the supply of water, the disposal of waste, and the control of pollution of all kinds. These endeavours protect public health by preventing disease transmission, and they preserve the quality of the environment by averting the contamination and degradation of air, water, and land resources.
It was traditionally a specialized field within civil engineering and was called sanitary engineering until the mid-1960s, when the more accurate name environmental engineering was adopted. Projects in environmental engineering involve the treatment and distribution of drinking water; the collection, treatment, and disposal of wastewater; the control of air pollution and noise pollution; municipal solid-waste management and hazardous-waste management; the cleanup of hazardous-waste sites; and the preparation of environmental assessments, audits, and impact studies.
Mathematical modeling and computer analysis are widely used to evaluate and design the systems required for such tasks. Chemical and mechanical engineers may also be involved in the process. Environmental engineering functions include applied research and teaching; project planning and management; the design, construction, and operation of facilities; the sale and marketing of environmental-control equipment; and the enforcement of environmental standards and regulations.
The education of environmental engineers usually involves graduate-level course work, though some colleges and universities allow undergraduates to specialize or take elective courses in the environmental field. Programs offering associate (two-year) degrees are available for training environmental technicians. In the public sector, environmental engineers are employed by national and regional environmental agencies, local health departments, and municipal engineering and public works departments.
The Term Paper on An Introduction to skills involving Knowledge Management
What if I were to tell you that I could give you a process or methodology that would allow those that don't know what they don't know to determine what they really needed? If I had a tool that supported a process of gathering required information, providing information to those that need it, when they need it, and in a form they understood, would people really be interested in such a tool? Well if ...
In the private sector, they are employed by consulting engineering firms, construction contractors, water and sewerage utility companies, and manufacturing industries. Ever since people first recognized that their health and well-being were related to the quality of their environment, they have applied thoughtful principles to attempt to improve the quality of their environment. The ancient Harappan civilization utilized early sewers in some cities. The Romans constructed aqueducts to prevent drought and to create a clean, healthful water supply for the metropolis of Rome.
In the 15th century, Bavaria created laws restricting the development and degradation of alpine country that constituted the region’s water supply. The field emerged as a separate environmental discipline during the middle third of the 20th century in response to widespread public concern about water and pollution and increasingly extensive environmental quality degradation. However, its roots extend back to early efforts in public health engineering.
Modern environmental engineering began in London in the mid-19th century when 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.
One example is the widespread application of the pesticide DDT to control agricultural pests in the years following World War II. 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 Carson’s “Silent Spring” (1962) is considered to be the birth of the modern environmental movement and the development of the modern field of “environmental engineering.
The Essay on Water Pollution 16
Water Pollution People keep on throwing trash and industrial wastes into our clean water. If this continues, the quality of our water will deteriorate, and without it everything dies, including us. Water pollution is destroying our world, but fortunately we can count on special treatments for this kind of problem. What is water pollution? "It is the contamination of water by foreign matter such as ...
The sewage is usually treated in the treatments plants and then dumped back into the sea. Industrial waste the industrial business uses the fresh water that has to carry all their waste away. So then that means that all chemical get into the fish water and polluting the water. Oceans get polluted daily by oil and runoff. The ocean is probably the worse for getting polluted from oil because it happens really often by ships and boats. The sewage water goes off into different rivers without it even having any treatment done to it. And oil doesn’t dissolve when it’s been in the water for a while. What pollution also comes from people?
Like when they throw all their garbage like out on the streets or instead of throwing it away they just like throw it out of the car and they say other people will pick it up. So that’s where a lot of pollution comes from. Some of it also comes from buildings and boats like oil and chemicals and that pollutes the water to. water pollution affects plants and organisms living in these bodies of water. In almost all cases the effect is damaging not only to individual species and populations, but also to the natural biological communities. In the Philippines one of the major environmental problems is water pollution.
Upon a glance, you could say that the bodies of water in the Philippines are polluted, slowly dying, not being cared for. The current state of the aquatic ecosystem in the Philippines is dismal, and the ever increasing population of the country isn’t helping this problem. Only about 10% of sewage in the Philippines is treated or disposed of in an environmentally sound manner. The rest goes back to nature – usually the sea. In this context of poor waste treatment and high population growth, water pollution is a growing problem for the country’s groundwater, rivers, lakes, and coastal areas.
The Essay on Water Pollution 6
Water is a necessity to life on earth. All organisms contain it, some drink it, and others inhabit it. Plants and animals require water that is moderately pure, and they cannot survive if their water is affluent with toxic chemicals and/or harmful microorganisms. If severe, water pollution can kill large numbers of fish, birds, and other animals, in some cases killing all members of a species in ...
Polluting industrial material is also found in abandoned mining areas, with mercury pollution affecting water bodies in these areas. These problems are unfolding in a context of poor planning, and weak management and enforcement of regulations. There are effects of water pollution to us and some effects are as follows: Water Pollution Effects Waterborne diseases caused by polluted drinking water: Typhoid Amoebiasis Giardiasis Ascariasis Hookworm Waterborne diseases caused by polluted beach water: Rashes, ear ache, pink eye Respiratory infections Hepatitis, encephalitis, gastroenteritis, diarrhea , vomiting, and stomach aches
Conditions related to water polluted by chemicals (such as pesticides, hydrocarbons, persistent organic pollutants, heavy metals etc): Cancer, incl. prostate cancer and non-Hodgkin’s lymphoma Hormonal problems that can disrupt reproductive and developmental processes Damage to the nervous system Liver and kidney damage Damage to the DNA Exposure to mercury (heavy metal): In the womb: may cause neurological problems including slower reflexes, learning deficits, delayed or incomplete mental development, autism and brain damage In adults: Parkinson’s disease, multiple sclerosis, Alzheimer’s disease, heart disease, and even death
As discussed in the paper, water pollution has not ceased to exist. In fact, it is safe to say that water contamination has increased over the years. Population growth, industrialization, urban sewage, human waste, point and non- point sources, chemical run- off, the unmonitored discharge of pesticides and fertilizers into our rivers, lakes and streams, as well as, the man- made changes to freshwater systems are many of the factors which have contributed to the gradual increase of water contamination.
Since water pollution results from such wide variety factors, it is not surprising, that the issue has not yet been solved or at least efficiently managed. Water pollution is bad for the environment and for people that drink it. The topic is about all the water pollution and trash and toxic chemicals that get dumped into the water. It’s also not good for all the living organisms that are in the lake or rivers because of water pollution. Water pollution is bad because it’s not good if people drink it and for all living things in the water that drink it also and get really sick.
The Essay on Water Pollution 5
With the development of modern agriculture and industry, water pollution has been a major problem. The reason why this issue became so important these years is that the water pollution can not only poison the creatures in the water but also affect the quality of our drinking water. Causes The main cause of water pollution is human activities, which means the human being pollute the water by ...
Aren’t we aware of the different problems occurring in our nature, especially in different bodies of water? Water pollution is the cause of our undisciplined actions and irresponsibility. We, humans are only creating problems that consequently we will also carry the burden of these problems. We all know that water pollution can affect our health badly and seriously. It can cause such sicknesses and diseases that will badly affect our health. We all know how important water is. Water is essential to our body. Neither we nor every living thing can’t survive without water.
And so therefore, we should keep, protect, save, and help prevent our waters from being polluted, we should act as early as now, we should save rivers, seas and oceans, and other bodies of water because we will also bear the burden of this problem. We should not wait for the time until people are competing just to get sufficient, fresh and clean water, the time where clean water is insufficient to the people and animals, and the time where in our sources of water are diminishing or until the time where there are totally no sources of water.
And so, let us be disciplined and responsible enough to save, protect and conserve not only sources of water but also our mother nature because our nature provides and helps us in our daily lives. Let’s just realize how important our mother nature is. It is our only source of living. Let us not destroy it nor pollute it. Let us act for a change. We need and we should help save and conserve our mother nature, especially the different bodies of water. Absolutely, there are many simple ways in how we can help. Change ourselves before we construct changes in our nature.
