Essay on Case Study Lake Dianchi

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.

Native Plant Study- The area that Lake Doonella is located in has great vegetation and variety of native plants which gives the native animals and local residents a beautiful home as well as a lovely sight for tourists. There are numerous different plants in all different shapes and sizes that call this area home. Some plants even have berries growing on them in many different colours for the animals to feed off. During the field walk there were many trees and plants but the most commonly viewable one was the Scribbly gum. ( shown in .. (ref off iBooks)

More than 24 billion gallons of untreated sewage waste and storm water are pumped into the lakes annually. Pollution is increasing as well, due to the cottage development, where people enjoy spending their summers relaxing. For many years, the lake habitats have been affected by pollution and habitat destruction. The market for fish is tremendous; so much so, that we have depleted our fishing resources, and have had to market on invasive species.

Lake Erie is thriving biologically but not in the way one might think. It’s poisoned with toxic algal blooms that grow in the phosphorus-concentrated waters millions of Canadians and Americas alike depend on for drinking water. Unfortunately, this is also not the first time this has happened to the Great, not-so-great Lake.

Phosphorus, “...the primary algae-feeding nutrient in Lake Erie, and contributed to the largest algae bloom in history last year” (McCarty, para. 3), is a key factor in how

To assess and analysis the long term trends and seasonal trends of Phosphorus in relation to the lakes system within the catchments.

Water column phosphorus concentrations have also been shown to increase under anoxic conditions (Webb, K.L. and D'Elia, C.F. 1980). This is because some of the iron oxyhydroxides that

I’m reporting to the watershed area of the Conodoguinet Creek to discuss possible pollution in the creek. A type of pollution that can be a problem is Eutrophication. Eutrophication is the enrichment of an ecosystem with chemical nutrients. The Conodoguinet Creek runs through agricultural land, which means a lot of fertilizer. Phosphates and nitrates are found in fertilizers. When farmers use too much fertilizers, it can leak into the creek when it rains. When a lot of fertilizer gets into the creek in can get too many nutrients, and then excessive amounts of algae will grow causing many more problems. Acid rain is also another problem. Acid rain is caused by fossil fuels being burned, from cars, factories, etc. Acid rain can get into the

How does the LSC potentially influence the phosphorus cycle of Cayuga Lake? Include in your explanation relevant details of the LSC system and the ecological properties of Cayuga Lake.: Based on some assumptions, the LSC contributes 2.4% of all of the phosphorous that is in the southern lake basin. The monthly max LSC contribution to phosphorous loading is around 6.4% during August. There is no measurable oxygen depletion in the lake and there is no measurable increases in algal growth. Consequently, implementation of LSC will not cause or contribute to growth of these nuisance organisms.

Eutrophication is when there is too much nutrients in the water, as stated above. Eutrophication can come from farmers fertilizing their fields and some detergents. We tested for phosphates, salts or ester of phosphatidic acid. We also tested for nitrates, salts or ester of nitric acid. The more the phosphates and nitrates, the more eutrophication is present in the stream. We tested for dissolved oxygen, the amount of oxygen in the water, as well. We found found a very low level of phosphates with an average of 0.1 parts per million (ppm). We also found a very low level of nitrates with an average of 0.9 ppm. The dissolved oxygen level was 9.8 ppm. The higher the velocity of the water, the more dissolved oxygen it will contain. All of these measurements are very good and show that there is little or no eutrophication in the

Back to the history, the eutrophication problem was first time concerned by public on Great lakes at the 1960s, the Lake Erie was covered by algae as a result of over dumped phosphorus from the sewage and other waste water, at that time, the Lake Erie was known as the “Dead Sea of North America”(Fitzpatrick, J. J., and Di Toro 1999). The reason cause this problem can be concluded in 2 points, 1. the stresses of overfishing, 2. development of phosphorus-based detergents. At the end of 1960, the Canada and the United States have realized the penetrance of this problem and finally sit on the table to sign an agreement that limiting phosphorus dumps to the Lake Erie, and plan to control existing unstoppable algal growth. Because of the awareness of Canada and US government, the concentration of phosphorus got a significant success. And this problem happened again during the 1990s, but this time the reason why this happen is more complexly.

The rise in phosphorus causes algae to bloom, and the toxins from the algae bloom result in unsafe water conditions for humans and animals. Phosphorus pollution appears everywhere in the state from individual wastewater facilities in urban areas to farmland water runoffs in Lower and Central Minnesota. It is a danger because it causes algae to thrive and algae bloom can be toxic to humans and animals. Phosphorus pollution affects people and pets such as fishermen, swimmers, and boaters. It also affects urban and suburban communities such as Mounds View that are built around lakes and freshwater bodies. Therefore phosphorus pollution is a danger to the population of Mounds View Minnesota, but can be reduced by use of alternative fertilizers and use of phosphorus free

Let me go all APES here. Water contamination has been an issue across the country. Nutrients like phosphorous, which are found in many fertilizers, can runoff into streams and rivers causing eutrophication. Eutrophication is just a fancy word for these organic nutrients causing a reduction in dissolved oxygen in

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.
