Comparing Chemical Levels

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,

Wash your hands and all of the equipment with mild soap and water. As a final rinse on the equipment, use deionized water. Dry all equipment thoroughly.

Data analysis of long term trends and seasonal trends in Phosphorus at the Bosherston Lakes, South West, Wales.

This analysis of case studies from Los Alamos National Laboratory, and the case study to predict the effects of pesticides on aquatic systems and the waterfowl that uses them. Comparing the two processes of these case studies, along with analysis of the assessments. Describing the case study on the effects of pesticides in aquatic ecosystem, the risk assessment correlated to observed field studies and evaluate the importance of this type of correlation in general for all risk assessment efforts. Breaking down the ecological and social

The experiment we conducted was to see if the conodoguinet creek was polluted. We had three different experiments and each experiment showed that there was little to no pollution. The results we have will help notify the public and the health department if the water needs to be treated or not. We had the correct materials and background knowledge to complete this task.

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

In Mount Judea, Arkansas, there lies a hog farm very close to the historic Buffalo River, known for its natural beauty and amazing sightseeing. On the contrast, immense amounts of green algae have been found in its water in the past few years. As a result, suspicions have been expected with the possibility of the hog manure ponds leaking into the Buffalo River. This is an enormous environmental problem, as endangering a natural, free-flowing river is constrained in any aspect. The Big Creek Research and Extension Team (BCRET) from the University of Arkansas have recently drilled deep into these manure ponds in search of a leak and have accomplished their goal. (TFW). Around 120 feet below, there lies a wet place of soil that could possibility be the cause of green algae found in the nearby river. Individuals notice how big of a problem this can become. Three women, in fact, have appealed to constrain the amount of manure spread in the nearby fields surrounding the Buffalo River. (TFW). People love to see natural beauty, which is what the Buffalo River provides. Instead, they have to burden with the fact of green algae. Green algae can affect a body of water in many ways, including the contamination of turning these

Develop a hypothesis on which water source you believe will contain the most and least contaminants.

As the Great lakes play such an important role in providing safe drinking water to North America water quality and treatment are both important topics for the Great Lakes and the people that depend on them. We have spent billions of dollars to provide safe drinking water to citizen of North America and

The big question of this study is, Does Sawmill Creek have a good water quality, and a healthy ecosystem? We made a hypothesis stating that Sawmill Creek has a healthy ecosystem, and a good water quality. The findings were quite liked amongst people, with the pH right around 7, making it nearly neutral. The DO was a little different with getting two very different answers for both tests, but making it appear as though it has a good level, right around 10 ppm. The ecosystem is decently diverse, with the findings of different trees and plants around the stream, and the different macroinvertebrates, with only 1 aquatic plant found, which was algae. With all the plants, and macroinvertebrates, none of them seem to be polluting, or causing poor

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

Aim: The aim of the lab “Chemical Equilibrium” is to observe the effects of changes in concentrations of products and reactants on the position of the equilibrium of given chemical reactions.

Chemical equilibrium is the study of change within a chemical reaction and how far it will go to reach a dynamic equilibrium (Burdge). Dynamic equilibrium is defined as the constant movement of species in a chemical reaction, gone to incompletion while the rates of production and consumption are equal (Kf = Kr ) (Burdge). It differs from static equilibrium in that species are constantly being consumed and produced, it is dynamic movement (Fox). The concentration of such species do not change, it remains constant (Fox). The rate at which species are being consumed and produced is known as the equilibrium constant (K) (Burdge). Due to the fact that the concentration
