Stream Team And The Importance Of Turbidity In Water

What the stream team will be doing is going to the stream and seeing how much nitrate, phosphates, dissolved oxygen, turbidity, temperature, and pH is in the water. The stream team will look at the effect on water quality, the effect on plants and animals, the acceptable levels for swimming, sources and sources categorized, the best management practices, whether the sources are point source, or nonpoint source pollutants, and the test results. The stream team will be doing all of those topics over nitrate, phosphate, dissolved oxygen, turbidity, temperature, and pH. The stream team will also be going over the materials and procedures and talk about the results for each test. The presence of normal levels of nitrates usually does not have a …show more content…
If there is too much algae or sediments then it can make lakes and streams unsuitable for recreation and aquatic life. (“Turbidity: Description, Impact on Water Quality, Sources, Measures”) The significance of excessive turbidity in water on fish and other aquatic life begins by modifying the temperature structure of lakes. In turbid lakes and ponds bottom temperatures are usually lower than in clearer ones. Lower temperatures in many lakes means lower productivity. The penetration of light interferes with turbidity. The interference with turbidity can reduce photosynthesis and decrease primary productivity which the fish food organisms depend. Fish production is reduced as a consequence. (“Water Turbidity Effects on Fish and Aquatic Life | Learn Water Basics Students Teachers Public”) Turbidity (cloudiness of water) should at no time go above 5 nephelometric units. Turbidity can go no higher than 1 NTU in at least 95 percent of the daily samples for two consecutive months. The website does not say why the turbidity should not go above 5 neohelometrics.(Oram) Turbidity is caused by particles suspended or dissolved in water that scatter light, making the water appear cloudy or murky. Sources include soil erosion, waste discharge, urban runoff, eroding stream banks, large numbers of bottom feeders (which stir up sediments), and excessive algae growth. Turbidity is a non point source of pollution. (EPA) Effective turbidity management requires close adherence to several important controls, construction methods aimed at turbidity reduction, and revegetation and restoration of the construction impact areas.
