To the Board of Directors of the McMichael County Department of Environmental Health and Safety,
The Danieley River in McMichael, North Carolina has recently become polluted due to the large amounts of industrial factories in the area surrounding the river. The Danieley River in the past has been polluted, causing fish to become sick in the salt water aquarium that had been installed on top of the river, using river water. The pollution in the river could have come from any number of potential industries, and we were tasked with finding out which industries were causing the pollution in the Danieley River.
Using our sample of the Danieley River, sample I, we tested for eight potential pollutants. Each cation, or pollutant was tested by adding a sample of the river water to other chemicals that would form a precipitate or solid when they reacted together. If a solid formed it would tell us that this pollutant was present in the Danieley River. In our sample we found that the ions of Ba2+, Ca2+, and K+ were present in the River Water. This narrowed down our search for who was polluting the River to three potential companies.

This is potentially why the Ba2+ ion would have been found in the Danieley River. The Harmony Restoration and Hardware Supply Company could be dumping their excess Ba2+ into the river. We determined that Ba2+ was in our sample because we added K2CrO4 to our sample and the CrO42- ion would have bonded with the Ba2+ ion to form a precipitate. A precipitate was formed and therefore we can believe that the Harmony Restoration and Hardware Supply Company may have something to do with the polluting of the

This case is about Star River and how the firm is in the middle of financial crisis that was induced by rapid growth. The CEO basically wants to improve the financial health of the company and ask for help to make some decisions. The CEO asks one of the analyst for help in reviewing the historical performance of the firm, forecast financing requirements for the next two years, exercise the forecasting model to identify the key drivers of the assumptions, estimate Star River’s weighted-average cost of capital and lastly to analyze the proposed investment in a packaging machine.

Most of the rivers are the one being used by large communities like drinking water supply and for the farmers in their produce. The State of Department put together a commission of knowledgeable people and carried out an investigation about the risk and consequences of this project. Some of the conclusion about the spills were, for example, that: “A million of gallons of tar soil war poured into the Kalamazoo River in Michigan… 40 miles of this river still are contaminated to this day”. Another example of spills affecting communities, is the one in 2013, caused by a twenty foot crack in a pipeline, causing a huge spill of oil, damaging the residential neighborhoods and the Lake Conway in Arkansas. This spills and oil “accidents” are affecting not only the lives of people but also the wildlife, the ecosystems and the quality of air and water
This is an important topic. It affects the overall health of the population surrounding the Chesapeake Bay, as we eat from it quite often and it can be used as a water source. The chemicals being released into the water are from coal-burning factories and runoff, which can be helped, but it’s almost impractical in this day and age to spend the amount of money required to do so without the technology that can guarantee a fix.
... the residual effects of pollution left behind by both mining in the Chesapeake Bay area around rivers, such as the Susquehanna River in Pennsylvania, that feed into the Chesapeake Bay. Lutz also had quoted John Dawes, now the executive director of the Foundation for Pennsylvania Watersheds, on the damage done to streams and to the aquatic life in the streams. Dawes told Lutz "'we're looking at 4,600 miles of dead streams in Pennsylvania'" in reference to the vitality in polluted regions. This can occur in several ways but the two generally accepted causes are the toxicity levels in the water are too high to support life and the contaminated water is slowly killing off members of the food chains for the aquatic life. In either theory, the death of fish and their food chain caused by AMD is impacting the billion dollar fishing industry that calls Chesapeake Bay home.
The environment and the health of the surrounding population go hand in hand. The Environmental Protection Agency takes on this ever so important mission of protecting them both. The mission statement of the EPA states, “The U.S. Environmental Protection Agency's Office of Small Business Programs is to support the protection of human health and the environment by advocating and advancing the business, regulatory, and environmental compliance concerns of small and socio-economically disadvantaged businesses, and minority academic institutions (US Enviromental Protection Agency, 2010).” The impact of its mission can be defined clearly as it examines the impact of contamination in the air, the water, and the land on human health.
On October 6th, our school went on a field trip to the Conodoguinet Creek. We were not there to mess around but, we were there to do an experiment. Acid rain and eutrophication are two big problems in our area, and we as scientists went to the creek to see what the levels are of the creek. My hypothesis going to the creek was, if we test the creek for signs of pollution, then we can figure out how polluted the water is. Before going I did some back research and I thought that the creek was polluted before going on the study. With all the research I gathered we can see if the creek is polluted or not.
The Cuyahoga River received its name from the Iroquois meaning “crooked water” or “place of the jawbone.”(Britannica). Running through about 80 miles of land the Cuyahoga River became a centre of commercial transportation (Britannica). Cleveland, Ohio which is located on the Cuyahoga River was one of America's major industrial centers (Website). Until about the mid 20th century when the lower portion of the river that ran through Cleveland, Ohio became polluted. From decades of uncontrolled dumping of industrial hazardous waste which turned the water toxic(Book) and some of the waste also came from a lack of sewer systems (Website). To make this water even more dangerous the hazardous waste was flammable because it was a mixture of oil and chemicals(Book).
On January 9th, 2014, it was reported that a chemical spill has occurred from a storage tank owned by Freedom Industries. The spill occurred on the banks of Elk River in West Virginia, leaving hundreds of thousands of people without tap water. The company first reported that 7500 gallons of the chemicals had spilled into the river through a one-inch whole but had found that two weeks later, there was an estimated 10000 gallons of the toxic chemical in the river. The chemicals released include 4-methylcyclohexane (MCHM) and PPH. Methylcyclohexane is a chemical that is used in coal to reduce the amount of ash it produces(Field & Catherine, 2014). The West Virginia Department of Environmental Protection are still calculating the exact amount of how much of the chemicals were spilled.
The pollution of Lake Macatawa has reached a point where both government entities as well as local people need to do their part to clean it up. Through my research it is clear that Lake Macatawa has a clear pollution problem. The pollution problem is an underrated issue because its lack of coverage and its potential significant impact. Lake Macatawa is connected to Lake Michigan, which is a massively valuable natural resource. Lake Macatawa’s pollution is an issue of which needs to be taken care. Even though there are city ordinances, state-wide laws, and federal laws in place, Lake Macatawa still manages to remain incredibly polluted. The proof of the pollution can be shown through the clean-up effort that is going on now. The research includes
Then the documentary tackles Puget Sound. The Duwamish River is the largest hot spot in the nation. In 2001, the Duwamish River was classified as a “Super Fund” site. This is given to a site that will receive federal assistance for clean up. But yet, it may be too late. Puget Sound in contaminated with PCP, lead and mercury. The threat comes from the giant industrial polluters of old and from chemicals in consumers’ face creams, deodorants, prescription medicines and household cleaners that find their way into sewers, storm drains, eventually into America’s waterways and drinking water.
To help counteract the bank erosion along the part of the river that cuts through the town, people have filled in parts of the river with rock, as well as leveling the banks of the river to make it more of a slope. The goal in this was to slow down the erosion rates and to try and control the river. When the town decided to build a dam, the sediment that the river will typically move, piled up behind the dam and was unable to go through. Now that the dam isn’t there anymore, the sediment is able to flow down the river to different areas. Due to the fact that there is human development in this area, there is silt and chemicals, along with other substances that are dumped into the river from the towns and farmers upstream, which can affect the plants and animals. These pollutants include pesticides and manure, as well as other wastes. According to Minnesota’s Pollution Control Agency, the main impairment of the Zumbro River near Mazeppa is turbidity (“Minnesota’s Impaired Waters and TMDLS”). All of these pollutants can cause health risks if they get into the drinking water, along with causing plants and animals to
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.
Water Pollution is a current issue that has serious consequences; it progresses everyday in our lakes, oceans, rivers and other bodies of water.
