Engineering is defined as the science based profession by which the physical forces of nature and the properties of
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 Managment. 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
Everyone knows what the word poverty means. It means poor, unable to buy the necessities to survive in today's world. We do not realize how easy it is for a person to fall into poverty: A lost job, a sudden illness, a death in the family or the endless cycle of being born into poverty and not knowing how to overcome it. There are so many children in poverty and a family's structure can effect the outcome. Most of the people who are at the poverty level need some type of help to overcome the obstacles. There are mane issues that deal with poverty and many things that can be done to stop it.
America has always been a country known for their great integrity, diversity, financial prosperity and great pop culture. It has been a place many people have flocked to from many different parts of the world in order to escape their very own poverty struck countries in their quest to build a new life in America and hopefully become financially stable. In this article written by M. Harrington he pointed out some key factors discussing how America has not really changed from over a hundred years ago. In specifics he tells how many years have gone by and still yet there is still a very large amount of a poverty class of people. Although our nation takes great pride on its classlessness there is still a one quarter percent of our country’s population that still lives in a poverty level. Some of these areas also included some inner city blacks, farmworkers, Appalachian whites and elderly people. Harrington’s book “The Other America” also tells us how as a country we have managed to hide the poverty level class from being seen while our country screams we are the wealthiest country in the world! America has done just that. Encourage the wealthy to become wealthier and poor to be poorer. It was also pointed out that the poverty class tends to have a poor language, poor mentality and just a poor outlook of the entire world view as a whole. He stated that the poverty people in this country are identified by a unique way of what is called “Culture Of Poverty”. What he was saying was that the mind of a poverty struck person will not ever surmount to doing things that will benefit them or change the course of their direction. In other words you may give a poor man a million dollars but he will not know wha...

Laws and procedures are the most common basis for officers choosing not to allow offenders to remain free based on their discretion, a study by Mendias and Kehoe (2006) has found. The study found that laws or responsibilities were the main reason for a decision to suspend discretion in eighty-two percent of cases involving an arrest. The study also found that keeping the peace and procedural implications were the primary justifications for ex...
Several citizens in America may not empathize with many social conflicts which transpire in America. Unfortunately, when poverty is mentioned people of diverse gender, race/ethnic, and age can relate to poverty in America. Although several societies have not experienced the undesirable measures of relative or absolute poverty; several people know poverty exist through many channels, such as the media, social networking, history and charities.
Many reforms in the UnitedStates have been passed to help fight against the “War on Poverty”; but it has not been effective in eradicating poverty in the U.S. There are about 46 million people who are living in impoverished conditions and poverty continues to be a social issue in this country (Heritage Foundation, 2011) In the beginning, our country was formed under the belief that “this land is the land of opportunity and if we worked hard enough the American Dream can be gained” (Schwarz, 1997). People immigrate to this country today in hopes of becoming rich so they could gain a better life. In spite of coming to this country for a better life, many are faced with the lack of skills and money to succeed. In the end, most will end up in unskilled labor jobs that can barely support their families. Poverty continues to be a growing social issue because people have the “ inability to provide necessities like clothes, healthcare, and shelter” (Heritage Foundation, 2011) to help themselves and their family; therefore, many sacrifices have to be made to insure their survival. Yet many reforms made to help people living in poverty are based “off of outdated statistics” (Henslin, 2014, p.276) and are not enough to help the lower class maintain a sufficient standard of living. Poverty relates to conflict theory since the poor are struggling just to get by. Government programs such as Women, Infants, and Children (WIC), Supplemental Nutrition Assistance Program (SNAP), housing assistance, and food stamps provided by the government are not enough to help the poor gain social mobility.
A single water drop traveling from any river to any ocean is influenced with more than one hundred toxic chemicals and thousands of industrial pollutants. This is what people call water pollution, occurring in any state, country or continent. Unfortunately, throughout the centuries, water pollution has been an ongoing problem, mainly caused by the release of industrial toxins and chemicals. People around the world believe that plastic and metal make up the vast majority of this issue, but as years have come and gone, the quantity of chemicals released by small and large facilities are now the leading cause of water pollution. Although industries need to release waste somewhere, they should avoid putting it in waterways because it impacts the
Generally speaking, we face two major issues in trying to get rid of toxic chemicals in our freshwater. The first issue is the fact that we don’t know how to stop the chemicals from getting into our groundwater, as the contamination of groundwater cannot be seen, heard, or felt. If we know how to stop the chemicals from contaminating freshwater, we would be able to prevent water pollution before it gets out of hand.
During the summer and winter, the wastewater treatment plant in Alfred has to bring water to the facility if there is not enough flow into the system so bacteria can continue to grow during secondary treatment. The best time to work at the treatment plant is when flow is at a maximum during the fall and spring when college is in session. However, many pollutants are not removed from wastewater by treatment or by the environment. The most effective way to ensure everyone in the Village of Alfred is receiving clean potable water is to not pollute in the first place. Because we live in a materialistic world, another way to improve water quality is by increasing wastewater treatment plant efficiency by conserving water. Simply by reducing water use, life expectancy of treatment systems increases, prevent system failures, and minimize system costs, potentially saving hundreds of dollars. Some ways Alfred State College can reduce water use around campus
EPA developed the toxicity characteristic to identify wastes likely to leach dangerous concentrations of toxic chemicals into ground water .In order to predict whether The reactivity any particular waste is likely characteristic identifies wastes to leach chemicals into ground that readily water at dangerous levels, EPA explode or designed a lab procedure to undergo violent estimate the leaching potential reactions of waste when disposed in a municipal solid waste landfill. This lab procedure is known as the toxicity Characteristic Leaching
Hydrogeochemistry is a sub discipline of hydrogeology, which referred to as Chemical hydrogeology in some references (Domenico and Schwartz, 1990), and Groundwater geochemistry in some others (Merkel and Planer-Friedrich, 2005). One may also points to "Contaminant hydrogeology" used by Fetter, (1998) as another term that carries the same syllabus as Hydrogeochemistry. In all fields of science and engineering, sub-disciplines are develop to accomplish some missions, fulfill some requirements, and supplement the base subject. The same is true with Hydrogeochemistry. This sub-discipline is developing to deal with quality, contamination, chemistry, chemical processes, and reactions that take place in

Water quality can be described as the measurement of the condition of water relative to the requirements of humans, animals and plant’s need. When we talk about water quality testing, we are highlighting a critical piece of natural observing for civil engineers in order to create a specific structure or decision. At the point when water quality is poor, it influences almost every single form of life in our planet; going from plants to animals and thereon. Hydrology, in the other hand, is the study of water. It is important to state that hydrology is a critical part for civil engineers to determine and predicting decisions that will affect our biological environment.
...l forms of life, and the continued observance and regulation of water treatment by the government and independent companies to help create safer techniques for waste water treatment.
Engineering Mechanics deals with the rigorous study of mechanics, applied mathematics and related fields. This leads to an understanding of advanced analysis and leads to study in structural engineering, hydraulics, mechanics of solids and fluids, or properties of materials.
