A Correlation Of Dissolved Oxygen And Water Flow At Winthrop Lake

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,

The CTDEP collected bottom- dwelling fish and invertebrates and compared the quantity of organisms and number of species with the levels of oxygen in the water. Both of these studies confirmed that severe effects occurred whenever levels of oxygen fell below 2.0 mg/l. Large reductions in the numbers and types of aquatic life present were noted. The lab experiments recorded reductions in both growth and increase in death.

The samples of unfiltered Rio Salado River water used in these experiments were collected from a site on the south bank of the river near S. 7th Ave. in Phoenix Arizona (see figure 1). The samples of water were collected by filling a three-gallon carboy by submerging it in the river. The carboy was then transported at ambient air temperature to the lab the same day it

- Having more dissolved oxygen increases the number of fish observed in the body of water.

As the Dissolved oxygen increases so does the number of fish that are observed, until the ppm gets up to 14 then the

1. Based on the information in Table 2, it seems that the more dissolved oxygen in the water there is the higher the population of fish is.

Dissolved Oxygen, pH levels, Temperature Change, Fecal Coliform, BOD, Nitrate, Phosphates, Turbidity, and Total Solids were each tested in the stream at least one time. If more time and enough supplies were given, then certain tests should be done more than once. Temperature Changes should be tested every other month because it is quick and a change in temperature can affect the health of the organisms living in the stream and therefore the quality of the stream. Temperatures can also drastically change in a short amount of time and there is a large difference in water temperatures in summer and winter. Another test that should be done every other month is dissolved oxygen because it is related to the temperature of the water. Cooler waters have a greater capacity for dissolved oxygen than warmer waters. This test is important because due to human activity and industrial processes, can increase water temperature and therefore decrease the dissolved oxygen levels. Certain organisms living in the stream need a sufficient amount of dissolved oxygen to survive. Another test that should be done more often is the

The purpose of this experiment is to collect water samples from El Rio Canal. Data such as dissolved oxygen (DO), Chemical Oxygen Demand (COD), and Biochemical Oxygen Demand (BOD) will be found. From the results of each group, Streeter-Phelps Dissolved Oxygen sag curve will be constructed. Then, the Streeter-Phelps sag curve will be analyzed and the group will increase an understanding of the limitations and assumptions using this curve. The amount of biodegradable organic matter and non-biodegradable matter found in the water samples will be compared. Ultimate BOD will be estimated by using the first order method or the 〖BOD〗_t vs.〖BOD〗_(t+1) method.

Eutrophication is when there is too much nutrients in the water, as stated above. Eutrophication can come from farmers fertilizing their fields and some detergents. We tested for phosphates, salts or ester of phosphatidic acid. We also tested for nitrates, salts or ester of nitric acid. The more the phosphates and nitrates, the more eutrophication is present in the stream. We tested for dissolved oxygen, the amount of oxygen in the water, as well. We found found a very low level of phosphates with an average of 0.1 parts per million (ppm). We also found a very low level of nitrates with an average of 0.9 ppm. The dissolved oxygen level was 9.8 ppm. The higher the velocity of the water, the more dissolved oxygen it will contain. All of these measurements are very good and show that there is little or no eutrophication in the

During the summers the oxygen content atop the water normally has a salinity level consistent with “more than 8 milligrams per liter”; but when oxygen content drops down to “less than 2 milligrams per liter” the water is then known to be in hypoxic state (CENR, 2000; USGS, 2006). Hypoxia is the result of oxygen levels decreasing to the point where aquatic organisms can no longer survive in the water column. Organisms such as fish, shrimps, and crabs are capable to evacuate the area but the fauna that cannot move either become stress and/or die. Due to this, many call the hypoxia zone the “dead zone” (Overview, 2008; USGS, 2006).

Our plan is research the phosphorus levels in Lake Monroe and Griffy Lake and compare them in terms of area surrounding and the impacts it has on the City of Bloomington. Due to the proximity of agriculture around Lake Monroe and Griffy Lake, we want to research the effects of agricultural practices such as pesticides on water. Specially, we want to see if there are differences between the body of water we use as a drinking water source, Lake Monroe, and Griffy Lake. We think it will be beneficial to compare the chemical levels in both bodies of water and evaluate the differences.

As literature reviewed, by (Harrmoes, 1982)(Hvitved-Jacbseb, 1982), the dissolved oxygen (DO) of receiving water body can decline due disposing of storm water discharge which can be its water quality meaningfully changes, those reduction of DO can have definite the biological impacts, and cause for fish kill in water. Odour problems, caused by putrescin in the spilling over water and on the banks of the receiving water furthermore effect related with low oxygen concentrations. (House, et al., 1993) , In NRUT report both water quality and water quantity impacts related with urban storm water combine to impact aquatic and riparian habitat in urban water way. Higher levels of contaminants, augmented flow velocities and erosion, alteration of riparian

The main component of this study is the Diel Cycle, a process which tracks various biogeochemical processes in ecological systems over the duration of 24 hours. The study takes place in the San Joaquin Marsh in Irvine, the area consists of 11 ponds with 60 percent of its surface area as shallow shelf and the other 40 percent being deep permanent water (Bowler, 2010). The diel cycles record numerous basic abiotic measurements, but the crucial aspects of this study are the dissolved oxygen levels as they alternate between days and nights. Dissolved Oxygen level is one of the main dictator of ponds’ ecological health, observing its fluctuations can help predict changes in the aquatic ecosystem (Nimick, 2010; Andrade, 2015). The dissolved oxygen

The first body of water had approximately 4 ppm of dissolved oxygen, 0 ppm of phosphorus, 5 ppm of nitrates, a pH of 5.1, and the temperature was 12 degrees celsius. The second body of water had approximately 4 ppm of dissolved oxygen, 0.3 ppm of phosphorus, 10/3 ppm of nitrates, a pH of 6.97, and the temperature was 9 degrees celsius. There were also lots of previous human interactions. There was lots of litter, spray-painted rocks and stakes. The ecosystem is built next to a trail so there will definitely be the human interaction of walking.
