The Effect Of Oxygen Deficiency On Lake Ontario

Methodology: The water samples will be collected utilizing sterile plastic water bottles from Lake Tarpon. The location the samples will be collected from is Anderson Park, by the boat docks, located at 39669 U.S. 19, Tarpon Springs, FL 34689. The water samples will be brought to Tarpon Springs High School to be tested, located at 1411 Gulf Rd, Tarpon Springs, FL 34689. The phosphate, nitrate, and dissolved oxygen levels will be tested utilizing various LaMotte water testing kits,

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

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

Lake Winnipeg has been a neglected problem in its wide international, provincial watersheds for several decades. Due to its immense size and severity of the problem, short and long term goals should be set. The ultimate goal should be to return the nitrogen and phosphorus levels in the lake to its pre-1970’s values. This will ensure that the communities in the watershed have safe drinking water, secure water supplies and a healthy aquatic ecosystem. There is no magic solution to the neglected pollution in the lake. In order to meet these goals, diverse parts of the watershed will need to collaborate together and fix one part at a time, so that someday, Lake Winnipeg will be back to its healthy state.

When was the last time you swam in the Great Lakes? Could you say that it was clean, could you say that the organisms were all healthy and doing great? Well, unfortunately, there are many things harming our Great Lakes, like chemicals, pollution, and invasive species.

The aim of this essay is to investigate the overall health of the Credit River located in Southern Ontario, Canada through data collected for phosphates, nitrates, dissolved oxygen and pH levels over many years. The Credit River originates around the city of Orangeville and then travels downstream for about 65 kilometers into Lake Ontario, near the Greater Toronto Area (Orphanos, 2004). It is essential to discover the health of this major river as it is one of the few which makes it way through the large urbanized zone including the city of Mississauga. There is a diverse wildlife that is supported by the water source, and it must be considered a priority to sustainably manage and investigate the concentrations of contaminants and water quality

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

Since the 1960’s, Lake Erie has been recovering from its unhealthy state and it’s public status. Lake Erie was terribly polluted that lead to fires and algae which was something locals were not happy about. Lake Erie’s water even got to the point of restriction. Pollutants were being dumped and phosphorus, fertilizers and pesticides were leaking into rivers that would later lead into Lake Erie. “As a result of these pollutants, Lake Erie contained increased levels of phosphorus and nitrogen, which contributed to eutrophication - a process that encourages the development of algal blooms.” (Rotman). Lake Erie was even known as the “burning river” or even the “dead lake”.

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

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.

Climate change is a change in the average global or regional weather patterns. Climate changes includes factors such as; temperature, precipitation, humidity, wind and seasons, influenced by oceans, land surfaces and ice sheets. This plays a

Water is an important resource and weather agent in our world, and the Great Lakes Region has an intimate relationship with water. The region was shaped by glaciers long ago and continues to be shaped by flowing surface water today. Groundwater is very pure in the area, which allows for plants, animals, and humans to thrive there. Migration into the area can be related to the groundwater found there. Human use of the water results in man-made structures, water flow alteration, and changes in water quality. Water is very influential in the Great Lakes Region.

In Lake Erie, there is out-of-control algae growth that created dead zones. The problem has become critical in the western Lake because of harmful chemicals. Contaminants in fish certainly are causing health problems. At present, the solution is to make

Eutrophication is a harmful process that occurs when an excess amount of nutrients enter into a water system. These nutrients, such as nitrates and phosphates, enable plants to grow and are only beneficial to an ecosystem in small amounts. When an excessive amount of nutrients enter a water system, an explosive growth of algae is stimulated, creating an extremely low oxygenated environment where fish and other organisms are unable to survive (Rhyther et al. 1771). These excessive nutrients are sourced back to a range of anthropogenic activities such as, discharge from sewage treatment plants and septic tanks, and stormwater runoff from over fertilized lawns, golf courses, and agricultural fields (NOAA). Globally, eutrophication has become one of the largest pollution problem affecting coastal waters (Howarth et al., 2000). United States has the second largest consumption rate producing 220 million tons of waste per year just behind China who produces 330 million tons per year (Duan et al. 2008). These enormous amounts of wastes are harming vital parameters of ecosystems. For instance, Chesapeake Bay off the coast of Virginia is the largest estuary in North America and 70 % of it is polluted (Boesch et al. 2001).

Eutrophication refers to the effects and involvement of the varied nutrients in aquatic systems. It is defined as the enrichment of water by nutrients, primarily nitrogen and phosphorus, which causes an increase in the rate of supply of organic matter to an ecosystem. This increase in organic matter hastens and accelerates the growth of algae and other forms of plant life. Most of these algae and plant life produces detrimental damage and disturbance to the ecosystem present in the water and the overall water quality (Andersen, Schlüter, Ærtebjerg, 2006). The process of eutrophication commonly happens over a long period of time, but human activities have accelerated the rate and degree of eutrophication of rivers and lakes which causes an excess nitrogen and phosphorus in the water quality (Chislock, Doster, Zitomer, & Wilson, 2013).
