Importance Of Water Quality Analysis

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 vials were placed in the water and the oxygen levels were read every 5 minutes until 30 minutes was reached. As the oxygen levels were collected they were put into a table that had all three tubes labeled at each 5-minute increment. After 30 minutes the experiment was completed and the clean up process could begin.

Abstract: Photosynthesis, the conversion of inorganic carbon into organic glucose molecules using light energy, is one of the most biologically important processes on Earth. It is imperative to study how the rapidly increasing carbon dioxide concentrations in the atmosphere since the Industrial Revolution may affect photosynthesis of photoautotrophs. In this experiment, a look is taken at the question: does inorganic carbon availability affect photosynthetic activity. This experiment uses bicarbonate as the inorganic carbon source, and analyzes how varying concentrations of bicarbonate may affect the photosynthetic activity of the South American aquatic plant Egeria densa (also known as Elodea densa) by measuring its O2 production in distilled water and 0.1%, 0.4%, 0.6%, 0.8%, and 1.0% sodium bicarbonate solutions. T-tests between the control (distilled water) and each bicarbonate treatment are conducted using the online program GraphPad. All tests results in a p-value greater than 0.05 and a calculated t-value greater than the critical t-value, thus rejecting the null hypothesis, indicating that inorganic

The purpose of this experiment was to simply measure oxygen production rates released from decomposed hydrogen peroxide under different conditions (concentration of enzymes, temperature, and PH level).

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

The increase of oxygen does not necessarily mean the fish will keep up with it. Too much oxygen can be harmful to the fish so you would need a certain amount per area of fish. A constant flow of oxygen going throughout the water habitat.

We did 3 different test to help conclude the water quality. The first testing/station i did was to see what kind of critters were living in the water. Then, my next group was to take a test to see if eutrophication was in the water. We also took

Acidity is the level of acid in a substance such as water, soil, and even wine. Dissolved Oxygen, or D. O., was another test. Dissolved oxygen is the amount of oxygen that is present in the water. Group P’s data showed 8, 8, 12 for D. O. Groups A’s data was 10, 8, 7. Group W’s data was 12, 11, 12. The average was 9.8. This is a high but excellent number. We want this to be high so more organisms like fish can live there. The pH scale said for groups P, A, and W that the pH was 7 which is neutral.

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

Dissolved oxygen varies depending on the temperature in the water, salinity, oxygen depletion, oxygen source and other parameters (Stoddart 2014). Biochemical Oxygen Demand BOD can be defined as the amount of dissolved oxygen that microbes utilize to decompose organic matter in the water (Academic 2015). Results from BOD can be usually found after 5 days. However, some times in order to get a complete biochemical Oxygen, BOD must be measured for 20 to 25 days (Pisarevsky 2005). Chemical Oxygen Demand COD measures all organic carbon in a water sample by oxidizing organic matter with strong chemicals. COD is a chemically/thermal oxidation reaction. COD includes both biodegradable components and non-biodegradable components (Levarage

The test subjects, O. rusticus crayfish, were collected from the White River.. Body length and body weight were measured with the use of a measuring tape and a gram scale. The rate of oxygen consumption was studied by the use of intermittent closed respirometry with a Q-box AQUA device. This was conducted by measuring the amount of dissolved oxygen present in the water chamber without removing the organism from the container so as to demonstrate the amount of oxygen consumed by the crayfish over a given set of time. By periodically measuring the amount of oxygen present in the water at an interval of twice per second, the rate of oxygen consumption can be

All around the world, countries are fighting to keep their drinking water clean. Whether it’s streams, rivers, or lakes, countries have taken great measures to maintain high quality drinking water for both human consumption and animal consumption. Countries must first understand the sources of the polltion, then determine the best methods to eliminate the pollution. Clean drinking water is a valuable resource and a the key to human survival. Plants and animals also depend on water for their growth, so all water must be kept clean. The major contributors to water pollution can be classified in three categories, industrial, agricultural and municipal.

The report finds BOD levels meet the National Pollutant Discharge Elimination System (NPDES) permit renewal standards. Results for suspended solids shows an opposite trend. Suspended solids increase throughout the course of the water treatment. This does not meet NPDES standards. Further suspended solids test will be needed to insure a minimal amount of error. If the same trend continues, the facility may need to be redesigned to meet NPDES standards.

One of the most important natural resources we have on this planet is water. Water covers roughly 70 percent of our planet and is the very foundation for every single species on earth. We as humans, rely on water more than any other resource on the planet and we simply can’t live without it. Although water is abundant around the world, clean water for millions of people is inaccessible. Around the world, there are people struggling to get water yet along clean water and it greatly affects our health. Improving clean water supply and sanitation, and better access to clean water resources, can increase countries’ economic development and can contribute greatly to poverty reduction and overall people’s health.
