Water Quality Index Of Kalamazoo River

525 Words3 Pages

In order to determine the water quality index of the Kalamazoo River in Albion, Michigan, a series of tests were conducted. The testing began on May 14, 2018, in the Albion Nature Center. Samples of water were taken from the Kalamazoo River to test the quality of the water. The data obtained from the samples have a corresponding value that is multiplied by a weighting factor to give a total. The sum of all the totals from each test gives a value from 0-100. In this range there are levels that determine the quality of the water: very bad, bad, medium, good, and excellent. The tests include dissolved Oxygen, Fecal Coliform, pH, biochemical Oxygen demand, temperature, total Phosphate, Nitrates, turbidity, and total solids. Dissolved Oxygen is the amount of Oxygen in the water and the test resulted in 38% saturation, giving a …show more content…

The value 10.23 was added to the index due to the pH of the water, which measures the acidity. The pH was found to be 7.5. Biochemical Oxygen demand is the amount of dissolved Oxygen used by microorganisms in the water and gave 0.00 ppm which corresponds to the value 10.56. The water temperature of 14 degrees Celsius resulted in the value 8.70. The total Phosphates resulted in 1 ppm and the Nitrates resulted in 5 ppm, giving the values 3.90 and 6.5 respectively. Phosphates help with plant growth, while Nitrates cause disease if found in abundance. The turbidity determines how clear a body of water is. In the site in Albion, the turbidity was found to be 3 feet and 5 inches, giving 0.40 to the total. Finally, the total solids added 4.76 to the total water quality index because it was 240 ppm. Total solids measure dissolved and undissolved material in a body of water. The final sum of values was 57.35, which means the quality of the water is medium. Because there is life in the river, this is a fairly accurate

The variables measured are nitrate, nitrite, total phosphorus, ammonia and transparency. Harrison also states that river and Lake Eutrophication is a problem across most of Europe because of excessive nitrogen and phosphorus levels from agricultural, industrial and domestic effluents. Harrison states that natural organic matter is present in most natural eco systems.

Nitrates should be greater than or equal to one parts per million (ppm), phosphates should be less than or equal to .1 ppm, and the pH values should be about equal to seven. The dissolved oxygen in the river depends on the temperature, if the temperature is cooler than the dissolved oxygen levels will be higher, but the recommended amount of dissolved oxygen should be greater than or equal to five. For a healthy river the turbidity levels should be 120 centimeters

We also did not find a high level of phosphates and nitrates in the water. My group also did a dissolved oxygen test on the water. The velocity of the surface water of the creek is at a normal rate. The Conodoguinet Creek appears to be healthy right now.

One of the most difficult challenges that faces our society about water pollution is cleaning after a body of water have been contaminated. Our design team aimed to design a sufficient water filter that would improve the water quality in a body of water have been contaminated. An ideal body of water should be contaminant free, with a high potential Hydrogen (pH) and Nitrogen Dioxide (DO) level. Low pH and DO level which could cause health hazards to individuals who used the water as a drinking water. 2.

phosphates and nitrates ) - which is when fertilizers < such as those on farms > can seep through the soil or even run down the soil - called runoff - into the creek causing the water to have more nutrients than it should. ) Depending on how much pollution there is depends on how much algae there is ( the more eutrophication -there is the more nutrients in the water- results in how much algae there will be.) We were also testing on the pH scale ( which measures the acidity or alkalinity of water ) goes from 0 - 14 where 6 - 0 is higher acidity and 8 - 14 is higher alkalinity ( alkalinity is what neutralizes/destroys acid. ) 7 on the pH scale is neutral and that is the ideal water for the ecosystem. The pollution that we were testing for is where the acid came from to begin with.

The high amount of limestone in the creek neutralized the acid rain that was pouring on the creek. This can also make ph scale go into the alkaline side of the ph scale. The ph scale is healthy, because if it was to acidic it will be unhealthy for the fish. These were some of that factors that were in the

The built-in probe in the chamber measured the dissolved oxygen concentration in the chamber’s water (mg/L), which could reflect the oxygen consumption rate of goldfish. After the fish accommodated to the new environment, the oxygen concentration data were collected every 20 seconds for 10 minutes by the Logger Lite program. The data were then plotted into a scatter chart and analyzed with a linear trendline, to obtain

In this day and age, there are so many environmental issues that plague our planet that it can be difficult to zero in on local issues that we can improve on. Here in New York City, one of these lesser discussed environmental issues is local street drainage and its negative affect on the water quality of local waterways. While this problem may not seem as catastrophic as global warming or habitat destruction, it does have a big effect on the local quality of life, and the quality of NYC aquatic environments. New York City is an old city with an old infrastructure. In many places, the city has combined sewers.
