Assessment Of Bod, Cod As Organic Pollution Indicator Levels Of Varhala Lake Essay

Introduction: The purpose of this research is to determine whether there has been a change in the overall water quality of the Lake Tarpon Basin, and if so, whether the quality has improved or worsened. The variables that will determine whether the quality has changed are: nutrients (phosphates and nitrates) and dissolved oxygen (DO). The expected changes are lower dissolved oxygen levels (from the already low levels), higher nitrogen levels (from the already high nitrogen levels), and the state qualifications still are not met for nutrients and dissolved oxygen (Levy, Flock, Burnes, Myers, Weed, River 2010). This topic relates to environmental management because the changes in water quality would be due to pollution, which relates to the question “How does human activity lead to the pollution of water stores?” The hypothesis that will be tested is that Lake Tarpon’s water quality will have worsened since the last measurements by Levy, Flock, Burnes, Myers, Weed, and Rivera in 2010.

Pollution is the presence of dangerous and unwanted substances in the ecosystem that causes imbalance and health hazards to the living. Water pollution is the presence of unwanted substances or particles in water, which causes imbalance in water systems. Lake Huron is among the largest fresh water sources in the States located in North America.

First a background on the problem with water pollution must be given. Both oceans and freshwater

Many contaminants settle out of the atmosphere, such as acid rain, the pollutants and nutrients will transport from distant places by air depositing into the lake as the form of rain. The first pollutants as atmospheric deposition on the Great Lakes were phosphorus. It is found that about 20 percent phosphorus entering Lake Michigan comes from the atmosphere by determination of rain, snow and dust. Since phosphorus pollution generated by this approach cannot be controlled, so it is more urgent to reduce the phosphorus content of detergent, sewer and effluent fertilizers. People found fish in a lake of Lake Superior in a remote island containing PCBs and toxaphene, and this place isolated with no direct way to pollution. This determines the long-range transport of pollutants through the atmosphere and settlement in the lake. In fact the processes of material transport through atmospheric was very complex. For instance PCBs was insoluble in water, so as to re-enter the atmosphere during evaporation or connected together into small particles. A lot of PCBs volatilize from the lake, meanwhile, PCBs coming from various parts of the air mass experience the sedimentation on the lake. Other than that the contaminated sediment is another way to cause pollution of the lake. This is problems of the most urban industrial areas. Even if there is likely to remove severely contaminated sediments in

To analyze the environmental monitoring policy and its resulting measurements in surface waters to determine the differentiation with respect to stream size and flow rate.

The purpose this issue became of great significance these years is that the water pollution can not only poison the creatures in the water. Also affect the quality of Biodiversity declines

Water pollution in a unique ecological system called the Great Lakes has recently become a national problem for the two countries - the USA and Canada. The primary ways by which the Great Lakes were polluted for many centuries include wastewater discharge, toxic pollution of water with heavy metals and pesticides, soil erosion, as well as urbanization and, consequently, air pollution.

Sediments are the main source of water pollution, contributing to turbidity issues as well as irregular or harmful nitrite/nitrate, phosphorus, and pH levels. This contributes to the death of marine organisms and can also change which organisms can survive in the body of water as its conditions change due to runoff. Anthropogenic runoff is also a contributor of adverse water effects, such as cultural eutrophication from fertilizer runoff, and also results in the death of aquatic animals and shifts in which organisms are more prominent in the ecosystem. This lab will address the effects soil will have on variables concerning water quality. There is also the option of including fish and/or aquatic plants in the water column, which are independent variables as well as the soil. The pH, ammonia levels, nitrite levels, temperature, D.O., and physical attributes are the dependent variables that will be measured during the lab. The qualitative physical tests (turbidity and odor) will portray the physical state and cleanliness of the water, as well as the level of runoff from the soil.

Don’t you want he plants and animals living in the lake to have a healthy environment so they do not die off? With pollution it causes algae blooms to form. When algae blooms form, they can release toxins that can sicken and kill animals that live in the water. Fish die from having so much pollution. Would you want your environment to be polluted so much that you die? Just because fish are animals does not mean that they get less respect.

Water pollution is defined as “a change in the chemical, physical and biological health of a waterway due to human activity” (1). Over the past 50 years, pollution in the Great Lakes has been a rising concern. Pollution in the Great Lakes includes the disposal of sewage, heavy metals, invasive species, and pesticides that come from factory dumping, runoff of agriculture, nautical transportation, and air pollution. According to an article published by the US Department of Commerce, roughly 40 million people depend on the Great Lakes for drinking water, sport, power (electricity), and transportation (McCartney). The negative consequences of water pollution include, but are not limited to, the killing off of vital organisms, an increase in birth defects, infertility, malfunctioning nervous systems, and learning disabilities (McCartney).

With the vast diversity of pollutants being introduced to these waters, it is becoming more and more difficult to analyze and identify the exact effects each pollutant has on the water quality as well as the organisms living in them (Howe and Clark, 2014). Scientists, though, have discovered new ways of identifying these negative effects the pollutants have by analyzing certain

The quality of water in the Great Lakes not only effects the different species living in the lakes, but human health, all over Canada as well. “The five lakes occupy an area greater than half a billion square kilometers, have a shoreline of 17,000 kilometers, and are surrounded by a population of over 33 million.” (Sproule-Jones, Mark., 2002.) With the lakes being so massive there are plenty of different species living in them and people surrounding the lakes, living off the water. These factors make poor water quality an even bigger issue. Pollution can be seen in many forms; such as fecal contamination, toxic contamination from metals, nitrates and pesticides,

All around the world, countries are fighting to keep their drinking water clean. Whether it’s streams, rivers, or lakes, countries have taken great measures to maintain high quality drinking water for both human consumption and animal consumption. Countries must first understand the sources of the polltion, then determine the best methods to eliminate the pollution. Clean drinking water is a valuable resource and a the key to human survival. Plants and animals also depend on water for their growth, so all water must be kept clean. The major contributors to water pollution can be classified in three categories, industrial, agricultural and municipal.

Water pollution affects plants and organisms living in these bodies of water; and, in almost all cases the effect is damaging not only to individual species and populations, but also to the natural biological communities.

70 % of our Earth surface is covered by water and almost 60% of the human body contain water for nutrient transportation. The unique characteristic of water is water molecule is the only substance in this Earth that exist in all three physical states of matter which are solid, liquid and gas. All human beings need water to survive. The national development over the years cause the rate of water pollution increased. According to Gebre & Rooijen (2009) water pollution can be considered as a sign that derives from economic growth and is a common phenomenon in urbanized cities in developing countries. In general, there are three main issues that related to water pollution which are the causes, effects and the way to decrease this problem.
