Introduction: The purpose of this research is to determine whether a change has occurred in the overall water quality of the Tarpon Lake Basin and, if so, whether the quality has improved or worsened. The variables that will determine if the quality has changed are: nutrients (phosphates and nitrates) and dissolved oxygen (DO). Expected changes are lower dissolved oxygen levels (compared to already low levels), higher nitrogen levels (compared to already high nitrogen levels), and state qualifications are not yet met for nutrients and dissolved oxygen (Levy , Flock, Burnes, Myers, Weed, River 2010). This topic relates to environmental management because changes in water quality would be due to pollution, which refers to the question “How does human activity lead to pollution of water supplies?” The hypothesis that will be tested is that the water quality of Lake Tarpon will have worsened since the last measurements taken by Levy, Flock, Burnes, Myers, Weed and Rivera in 2010. Methodology: Water samples will be collected from the Lake basin Tarpon samples using sterile plastic water bottles. The location from which samples will be collected is Anderson Park, at the boat dock, located at 39669 US 19, Tarpon Springs, FL 34689. Water samples will be taken to Tarpon Springs High School for testing, located at 1411 Gulf Rd, Tarpon Springs, FL 34689. Phosphate, nitrate, and dissolved oxygen levels will be tested using various LaMotte water test kits, following the instructions within the test kit. The LaMotte instructions for testing for phosphate are: fill the supplied test tube with 5 ml of water, add a Phosphorous TesTab, cap the test tube and mix until the tablet dries... half the paper... ... iteria."
