IV. 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.
V. 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,

I infer that the water quality was affected more by other factors. The two sites with about the same amount of human activity were McKinney Falls State Park and Bulls Creek. On the other hand, Wild Basin swimming is not allowed. Our results showed that the order from greatest to least amount of nitrate and phosphorous concentration was Bulls Creek, McKinney Falls, and Wild Basin at the lowest. Hence, because Bulls Creek was had the high amounts of human activity and nitrate and phosphorous levels, this relates
While rain does help replenish and dilute polluted fresh water, it also can contaminate it just as fast. Sewage waste and runoff fills the waters with pathogenic microorganisms and chemicals that reduce the dissolved oxygen levels. A loss in oxygen kills off fish and leaves their habitat murky and dark. High levels of nitrogen and phosphorus from runoff cause growth of algae and other harmful aquatic life. In an article on water pollution, it is stated that “many fish species require a minimum of 4–5 mg of dissolved oxygen per liter of water” (Scholz, Nathaniel). Scholz is saying that fish in the areas that become over polluted die off or are forced to leave their natural environment due to a lack of oxygen. The article continues to explain that the fish living in these poor conditions are consumed as food and the levels of toxins can multiply as it goes up the food chain, potentially leading to illnesses for humans. As more water is demanded, more water filtration plants are put into place to get consumable water to all in need. One gallon of contamination can make one thousand gallons of water undrinkable. In 1993, Michigan received heavy amounts of rainfall which affected Lake Michigan and the drinking water. The study of this incident is included in John Gary’s book, Can We Cope?, and is stated that:
The day the experiment was conducted was on April 18th 2016 at Spring Lake creek. Spring Lake Creek is located on county road E about less than a quarter mile from Williams road. In order for the fresh water ecology class to conduct
The spatiotemporal pattern of water quality in the Reedy Fork and Buffalo Creek watersheds exhibits a trend of river deterioration, mainly due to Fecal Coliform. Our study suggests that most of the pollution sources were related to human activities. Looking at table 2a to 5b, it is clear that, F.Col, coliform is the dominant parameter with the highest means in all the sites, both at the Reedy Fork and Buffalo Creek watersheds. However, there are higher mean values of this nutrient in the Buffalo Creek watershed than the Reedy Fork creek watershed. This is clearly visible by looking at the variation in mean variable concentrations for the individual sites through the years under study from the graphs.
The monitoring program includes field and laboratory components to identify sources of materials (nutrients, sediment, microorganisms, and chemicals) to the lake, evaluate in-lake water quality conditions, and examine the interactions between Onondaga Lake and the Seneca River. Onondaga County’s trained technicians collect water quality and biological samples at a number of key locations in the watershed. Streams flowing into Onondaga Lake are monitored to estimate the annual input of water and materials including nutrients, sediment, salts, and bacteria. Samples are collected upstream of the lake to help pinpoint sources of pollution. Accurate estimates of inflows are a critical component of the AMP, since they underlie many of the management
Abstract--Water quality is sometimes ignored by lake management until it affects fish production and aesthetic values and is significant to test the quality of lakes frequently, sometimes as many as multiple times a day since the water in the lake could be used as a drinking source for both humans and animals. Protecting the present quality of the lake is significant when it comes to avoiding future problems. Duckers Lake’s water quality was sampled in spring 2014. Variables that could measure the water quality of lakes include: dissolved oxygen (DO) levels, temperature, pH, turbidity, and phosphate and nitrates levels. Mean turbidity levels increased overall throughout the sampling dates, while pH seemed to decrease overall throughout
Overall the objective of this lab exercise was to introduce students to watershed ecology and the ecological factors that affect water quality. Students used biotic (macroinvertebrates ) and abiotic indicators to asses the quality of water in a freshwater body. Specifically students collected water chemistry data (hardness, nitrate/phosphate concentrations, dissolved O2 and pH) to asses the quality of water. Additionally macroinvertebrates from the benthic environment of a respective field site were collected, analyzed as well as catalogued. Collectively the results indicated that a greater species diversity was indicative of greater water quality(Lenat). Likewise within a freshwater ecosystems a negative correlation was found to exist between fluctuating abiotic factors,species diversity and water quality. It can be concluded that amongst the three field sites the ranking of water quality from highest to lowest is as follows; Great Brook Farm, Russell Mill pond, Lawrence Street Stream.
This project evaluates drought and water quality measures for North and South Carolina coasts. It provides a better understanding of how drought may affect the coastal region’s water quality. The project supports the National Integrated Drought Information System and the Carolinas Integrated Sciences and Assessments. It contributes to the Drought Early Warning System for the Carolinas. Individual questions are brought to attention during the data collecting process. Overall this project is to determine if there is a significant correlation between water quality and droughts. In addition to the overall project, an interesting research idea I proposed is the link between drought and fecal coliform present in water bodies. The results will be
This study concentrated specifically on eight potential indicators of poor water quality, including color, turbidity, chloride, total hardness iron, phosphate, nitrate, and pH. Of these parameters, nitrate is the only MCL substance, the remaining seven are considered SMCL's, and were measured strictly for aesthetic purposes. The composition of two water samples, yielding from sources of different regulation, was studied to develop a better understanding of contamination prevalence. The first sample was collected from a drinking water fountain found inside the Natural and Environmental Sciences (NES) building. This water is treated and cleaned after being extracted from the Floridian Aquifer. The second was taken from the edge of a pond in Simmons Park, found on campus. This water source intercepts significant surface runoff and works as a retention basin for the surrounding area. Before conducting the experiment, it was expected that the NES water fountain would provide a sample more in compliance to the MCL and SMCL standards set by the EPA when compared to the Simmons Park Pond water. It is likely that the color and turbidity of the pond water will yield higher measurements than the NES drinking water. This was predicted to be the result, as the NES drinking water comes from a source of
The best way to protect local bodies of water is to give the resources necessary for professionals to analyze the patterns of the ecosystem 2. Currently, information from water testing is extremely scarce and many individuals within the government do not understand the necessity for water monitoring and watershed preservation3. Although there are various laws that work by directly protecting public health, many of these laws do not focus on protecting the entire ecosystem. Much of this negligence is a result of the economic drawbacks and regulations on human development that are required to preserve local bodies of water3. A major issue that greatly affects the entire ecosystem and watershed is climate change. The rapid changing of water parameters has caused many dangers for aquatic organisms and the surrounding environment4. To truly understand this impact, water monitoring is a necessity to preserving the ecosystem and protecting the health of all
Our report involved participation in the remaining volunteer positions for Evergreen’s program, collecting water quality data and urban watershed restoration. We compiled the data from TRCA, PWQMN and Evergreen to perform spatial analysis on sampling sites and compare data-sets on water quality parameters. Through qualitative and quantitative research, our research hoped to address the following questions;
By characterizing the spatial and temporal variation in the water quality of rivers and streams, results from water quality analysis can provide an improved understanding of the environmental conditions and m help policy makers establish priorities for sustainable water management (Cooper et al., 2002 and Antonopoulos et al., 2001). Watershed-scale analysis of water quality variables can illustrate the changing influence of various human activities in different sub-basins and as one proceeds from headwaters to downstream. Reports on stormwater quality management program have shown that Greensboro currently faces water pollution problems in its main rivers and lakes (Greensboro Water Resources Dept., Report, 2013). Water quality at most of the regularly monitored stations in major rivers and streams in the county are below the United States Environmental Protection Agency (USEPA) standards suitable for human consumption and aquatic life sustainability including sites along the Buffalo Creeks and Reedy Fork Creek. The condition of the water in Greensboro Rivers and streams is related to land use and the quality and quantity of the rainfall washing off the landscape. In an urban setting like Greensboro, the predominant factors in determining the water quality characteristics of rivers and streams are the pollutants washing off Greensboro’s
