A Study On Water Creek Reservoir

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.

Furthermore, factory farms pollute drinking water sources. Manure and fertilizers are rich in nitrates and phosphates, which are very unhealthy for living things. They pollute groundwater sources by seeping in through lagoons of waste sewage that factory farms create. Lagoons of animal feces and spent fertilizers are a very cheap way of dealing with waste (NRDC). The chemicals travel through the soil to groundwater that the local communities depend on. Ingesting nitrate tainted water will lower the amount of oxygen a person can intake. This can lead to death for infants. Some of the pollutants can reach open waters if they are carried by rain or irrigation water, called runoff. Runoff pollutes ponds, lakes, oceans, and other open bodies of water. Polluted waters with high levels of nitrates kill fish, aquatic plants, and other aquatic organisms because they experience the same problems with oxygen intake. High levels of phosphorus in our waters cause algae blooms in open bodies of water. Algae blooms disrupt the ecosystem in the water and kill the organisms living in the water. They use up all the oxygen in

The culprit this time around is the farmland that makes up 63% of the Lake Erie watershed, or, more specifically, the potent phosphorous fertilizers being improperly applied to the land (McLean et al., 2014). Growing demand for food has placed increased pressure on farmers’ crop production, so many farmers compromise using more fertilizer less efficiently in

Even though, fertilizers are needed to supply essential nutrients to the growth of plants; an excess of them is one of the major issues contributing to pollution in the Chesapeake Bay Watershed. Fertilizers are mainly composed of two elements: nitrogen and phosphorus.(4) Throughout the years, millions of pounds of this nutrients are applied all around the Chesapeake Bay Watershed; everything not absorbed by the soil or taken up by plants eventually reaches the Chesapeake Bay through storm-water runoff. This nutrients end up creating algae blooms in the water, which reduce the amount of sunlight available to underwater grasses; not allowing plants to photosynthesize and produce the food they need to survive. Algae then decomposes creating dead zones killing fish and other species since oxygen is needed for any organism to live. (5)

Did you ever wonder how things you do everyday effect the Chesapeake Bay watershed and Its tributaries? Well, It turns out to be not so good. One of the main causes for the Bay’s bad health are nutrients which are caused by excess nitrogen and phosphorus in the air and water. Plants and animals need nutrients to survive but when too many nutrients are in the water they fuel the growth of algae blooms and create conditions that are harmful for aquatic creatures.

Harmful chemicals, manure, and pollution factor into it. These can cause large amounts of blue-green algae, which can be more of an issue then the nitrates. They take away oxygen from the water which would cause a decrease in organisms. In the article, “The muted voice in water quality debate is finally heard.” Mike Kilen (2016) says, “But while we focus on nitrates, we also can’t forget the dangerous bacteria and blue-green algae increasingly popping up in our rivers that are even more a danger to public health.” So although the fertilizer problem is important, the nitrates and phosphorous is not the only thing to worry

Environmental Protection Agency (EPA), "High levels of nitrogen and phosphorus in our lakes, rivers, streams, and drinking water sources cause the degradation of these water bodies and harm fish, wildlife, and human health." In the 2000 National Water Quality Inventory, states reported that agricultural nonpoint source (NPS) pollution was the leading source of water quality impacts on surveyed rivers and lakes, as well as the second largest source of impairments to wetlands, and a major contributor to contamination of surveyed estuaries and groundwater. Agricultural activities that cause NPS pollution include poorly located or managed animal feeding operations; overgrazing; plowing too often or at the wrong time; and improper, excessive or poorly timed application of pesticides, irrigation water and fertilizer. Since the 1960s, the high input of agriculture production has resulted in the surplus of nitrogen and phosphorus in farm fields, which run off into surface waters. High concentrations of nitrates and phosphates in surface waters could lead to eutrophication and instability of the aquatic ecosystems. Eutrophication is caused by the over-enrichment of water with phosphates and nitrates, a problem that has become a widespread in rivers, lakes, estuaries, and coastal

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.

In summary, there are many different factors that contribute to the health of the Susquehanna River. The factors include the pH, temperature, phosphate, nitrate and dissolved oxygen levels. Another factor is the wildlife living in and around the water. A healthy pH level is from five to eight. The tested level was within this range! The temperature was also at a good level because it was cold enough to have the healthy level of dissolved oxygen. The dissolved oxygen level was about nine. The nitrate levels were excellent, but the phosphate levels were just good because they were slightly above where they are supposed to be. Also, by analyzing the types of macroinvertebrates in the river, the level of pollution can be evaluated. The

The Conodoguinet Creek flows 101 miles through the Cumberland Valley of Pennsylvania. We traveled to just a small portion of the Conodoguinet Creek. In our area eutrophication and acid rain are common. Eutrophication is caused by sewage treatment plants, home sewage systems, and fertilizer runoff. Acid rain is caused by fossil fuel burning. If we were to test the Conodoguinet Creek for signs of acid rain, eutrophication or other types of pollution, then it would test with high levels of pollution. That way my hypothesis and what I thought about the pollution in the Conodoguinet Creek before I went there and tested the water.

The water in brooks, streams and creeks from Michigan to Puerto Rico carries a heavy load of pollutants particularly nitrates from fertilizers. These nitrogen and oxygen molecules that crops need to grow eventually make their way into rivers, lakes and oceans, fertilizing blooms of algae that deplete oxygen and leave vast "dead zones" in their wake. Therefore no fish or typical sea life can survive. And scientists warn that a federal mandate to produce more biofuel may make the situation even worse.

The effects of eutrophication will not be experienced downstream if the nutrients fail to enter the watershed upstream. A study by Ribaudo et al. in 2000 found that a cost-effective approach to reducing the hypoxic region is fertilizer management or reduction. Wu and Tanaka (2005) found that implementing a fertilizer tax is cost-effective and would reduce inputs of nutrients into the watershed. The federal government currently has a system that could grow and become more prevalent as farmers take action to reduce their runoff. A $3 billion United States grant is in place to fund cover crops for farmers. Cover crops are planted to take up excess nutrients in the soil and stabilize the soil to prevent erosion. This method, in addition to fertilizer reduction, has been effective in reducing agricultural runoff in Ohio. Almost 500 farmers in Ohio have applied for a portion of the grant to not only help their agricultural productivity, but also to reduce the impact of agricultural runoff on fisheries. Lawmakers already passed a law limiting the amount of agricultural runoff from farms in Ohio. For the next three years, participation with the guidelines is voluntary and encouraged, but the law will become mandatory after the third year. The voluntary efforts proved to be ineffective. The law was passed months before Toledo, Ohio experienced a water crisis due to toxic algal blooms in Lake Erie and many inland lakes. While the law does not address limits on fertilizer, it is a step in the right direction. More analysis will have to be done once the law takes full effect in

Eutrophication is the slow process that occurs naturally in aquatic ecosystems, such as lakes and ponds. It is a result of an aging body of water gradually increasing its concentration of nutrients. This happens because the intervaling death and growth of organisms that, for whatever given reason, don’t cancel each other out, and modify the fertility of the ecosystem. Eutrophication is not inherently bad, but the hastening of this process through artificial means can be very harmful to the ecosystem, and ultimately end in failure.

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,
