Tailing Breach Case Study

When I think about the different realms of science and engineering, it is difficult to think of a domain that is going to change the world as much as environmental engineering will, in the decades ahead.

River water near the spill showed elevated levels of lead and thallium, Mercury and arsenic cadmium and lead exceeding Clean Water Act standards designed to protect aquatic life as well as humans who come in contact with the water. Which can cause birth defects and nervous and reproductive system disorders?

While nitrates are one of the major contaminants in the area, San Joaquin Valley residents face drinking water pollution from many other sources including arsenic, coliform bacteria, and pesticides. Arsenic is a naturally occurring semi-metal element that is found in different types of rocks. While arsenic primarily occurs naturally, human activities impact the amount of arsenic in groundwater. Arsenic is not only toxic at high concentrations, but also harmful after prolonged exposure at moderately elevated levels. California recognizes arsenic as a human carcinogen and believes prolonged exposure to the element to be associated with various cancers, including skin, bladder, kidney, lung, and liver cancers. A study in Maine found a connection between water contaminated

Environmental sustainability is the ability to be able to continue a certain process or use a certain resource indefinitely (Mason). For example, if you’re using a certain resource and you know it’s going to run out one day, that resource is unsustainable. Sustainability is important because a lot of the practices that we do in modern society from agriculture, to energy source, and even development, are completely depleting our resources. This practices were also made to accommodate our fast pace lifestyle, everything is built and made to be fast and cheap, nothing is made to last anymore. Many people are realizing the importance of being sustainable and the world is slowly changing to sustainable practices like Renewable energy and sustainable agriculture, while also changing the fast and easy mind set to a more “reusable” one. Brevard College has boarded the sustainable train of the world by making several additions to the school like solar panels, alternative transportation options, a Fair trade and organic Coffee shop, and several environmental based clubs. Although they are heading in the right direction, many changes still need to be made in order to achieve a well-developed sustainable campus.

The amended remedy is cost-effective because the costs are proportional to its overall effectiveness (see 40 CFR§ 300.430[f][l][ii][D]). Overall effectiveness was evaluated by assessing three of the five balancing criteria: long-term effectiveness and permanence; reduction in TMV through treatment; and short-term effectiveness. The overall effectiveness was compared to the alternative's costs to determine cost effectiveness. Even though the alternative remedy does not meet one of the balancing criteria (reduction in TMV through treatment), site contaminants, consisting of relatively low concentrations of TCE and cis-1,2-DCE in groundwater, are present only within the groundwater use restriction boundary. Concentrations of these contaminants are expected to naturally attenuate below their respective remedial goals before reaching the groundwater use restriction boundary. Overall, the relationship of the overall effectiveness was determined to be proportional to the costs and, therefore, represents a reasonable value for the money to be spent.

This test went on to test this impurities on lab rates and found that the damaged the genitals, kidneys, liver and lungs, and know they are starting to find these same symptoms in humans.

In excessive concentration, cyanide is very toxic to the aquatic life and fishes are 1000 times more sensitive to cyanide than humans. Cyanide poisoning are one of the risks that birds and other wildlife are exposed, if they are using tailing ponds for drinking or swimming. Only few hundred birds are killed from cyanide each year. When cyanide is used in mining, some of this chemical gets spilled and some is in left within mine waste which often buried underground which is sadly close to ground water, leaving communities and public health officials worried about the side effects om drinking water, pollution and surrounding of ecosystem and wildlife. In 2000, a breach in a tailing (mining waste) dam at a gold mine in Baia Mare in Romania, resulted in the release of 100,000 cubic meters of cyanide waste into the surrounding watershed. Roughly all aquatic life in nearby waters died, while drinking water supplies were cut off for 2.5 million people. These similar cases took place in Japan, Canada and

Environmental engineering is a topic that I have only been introduced to this year, as I decided to take an online course in Environmental Science. Throughout my class, I learned the various positions offered in this field of science, and this particular one caught my attention. I particularly liked the fact that it used the principles of various sciences such as biology and chemistry and the engineering aspect of being innovative appealed to me as well. Throughout my shadowing experience, I had trouble taking pictures on my own due to an extensive photo release form; however, the woman I shadowed was kind enough to work around that by taking pictures for me and then filling out the release form after. The only other issue that I had with

In the groundwater samples (rural, city, and well samples), there were acidic contaminants, coliform bacteria contaminants, pesticide and herbicide contaminants, and metal contaminants. More specifically, the rural water sample had pesticide and herbicide contaminants, the city water sample had acidic and coliform bacteria contaminants, and the well water sample had metal contaminants.

I have always been fascinated by the complex relationship between humanity and their environment. Our home, planet earth, faces future consequences because of our actions, or lack thereof. After discovering my passion for environmental stewardship, I have decided to commit to a conscious lifestyle. Because of this decision, I plan to study environmental science in college where I hope to develop my knowledge of our planet and catalyze my passion into action for the environmental movement. At college, I hope to gain a distinguished education and catalyzed passion. The most important reason why I wish to attend college is to gain a greater understanding of our home and how human activities affect it. Therefore, I can achieve a strong foundation to support my efforts towards a sustainable environment. Additionally, I hope to catalyze my passion for the environment through student organizations and events. One of the

They devote themselves to people who will learn and transform how things are done and together, with the entire organization, this will drive change and address the root causes of inequity (EWB Vision 2020). The organization also works to transform how future engineers are taught and how practicing engineers can use their skills to conduct a positive change as global citizens (EWB-uk.org). EWB looks at turning ideas into actions. They join together compromised areas, that in turn brings different cultures together, this allows an understanding of the systems ready for development and a recognition of the deeper reason for the existing problems. EWB focuses on supporting great ideas, innovations to prepare the environment for change

From my experience of working on a farm, I have developed a true understanding of what it means to live sustainably. In my undergraduate years, I have chosen to pursue a major in environmental engineering. The main reason why I have picked this program of study is due to my inquiry and concern into why people continually damage our environment. After graduation, I plan to work as an environmental engineer and apply my experiences to improve and expand conservation efforts in order to protect and preserve our environment. I am interested in studying this topic because living sustainably and preserving our environment for future generations is extremely important to me.

Moreover, I am more passionate about the environment because I am getting more aware of the destruction of the earth we live in. I can see the natural environment and resources in my country were being ravaged and torn apart. Massive landfills are keep piling up with trashes, loggings are uncontrolled and forests are cleared, more rivers are dying and polluted, the air is dirty, filled with chemicals and dusts, and the climate is getting hotter as each day passes. These sights make me realize that I want to take action and stop these unending fate while helping the world advance toward a better future. This is why I decide to choose environmental engineering as my major, and I believe University of Washington is the perfect choice for me because the university’s top-ranked environmental engineering program in the US will definitely help to make my ambition become reality. I am confident that the University of Washington can be the place where I can get the opportunity to contribute ideas and perform various research projects to help with the advancement of the field’s

For WM the fuel, environmental charge included on a customer’s invoice is determined by first putting in the percentage of the WM Collection Fuel Surcharge Table or WM Disposal Fuel Surcharge Table into the overall invoice charges (excluding taxes). Next the environmental percentage is put in the sum of the total invoice charges and fuel surcharge calculation (excluding tax). Landfills produce harmful gases that if breathed in by people can cause serious health issues. The gases they let off also can ignite huge fires. If the water gets contaminated, then there is a long process to get to clean again and it cost 10 million dollars. Landfills also create a toxic soup of industrial and home-cleaning chemicals. These are just some of the impacts that solid waste management has on people and environments. My group has come up with different ways to solve these
