  • Importance Of Water Quality

    used in a salt form, such as, disodium or calcium disodium EDTA. Turbidity Turbidity measures water clarity and how cloudy or muddy the water is, high turbidity levels from suspended and colloidal solids in the water, decrease the passage of light, and plant growth. This in turn affects the fish and invertebrate communities which feed on and live in the plants. Materials that can cause turbidity are silt, microorganisms, plant material and chemicals. However, the most frequent causes of turbidity in rivers and other water bodies are algae and inorganic material from soil weathering and erosion. Higher turbidity increases water temperatures because any suspended material absorbs heat from the sun. Warmer water holds less dissolved oxygen than cold; therefore, water with high turbidity has less concentration of dissolved oxygen. The water also loses its ability to support a large variety and number of aquatic organisms, as there is less light penetrating the water, there will be less photosynthesis occurring, reducing the levels of oxygen in the water. Turbidity is measured in nephelometric turbidity units NTU. Turbidity can be measured using a Turbidity Tube, it is inexpensive, easy to use, and does not require batteries or testing. To determine the turbidity, the tube must be observed from the top of the tube with the water filed until the bottom of the tube is not visible. For a more accurate reading of turbidity, an instrument called a Nephelometer is used, it measures…

  • Case Study: Standing Bear Lake Ecosystem

    whole state of Nebraska. This climate includes hot summers and dry cold winters. It is very humid and averages 30.6 inches of precipitation annually, with frequent thunderstorms. The microclimate of my ecosystem is hot summers, and dry cold winters with lots of snowfall. The lake freezes over every year in the winter months, and the lake in the summer months goes up and down in water level. The paths are shaded and the days are sometimes windy. My ecosystem also has many abiotic and biotic…

  • Loughberry Lake Lab Report

    This experiment was designed to test what the limiting nutrient was in Loughberry Lake, as well as examine the trophic state of the lake. In order to find out what the limiting nutrient was, we performed a few different tests. We began with a secchi disk test to see the transparency of the water. Then, we took water samples that we later used to test the turbidity levels of the water after adding varying amounts of phosphorous and nitrogen. Phosphorous was the limiting nutrient in the lake,…

  • Exploring Water Quality In Coastal Environments

    Introduction: Water quality is the scientific measurement describing the cleanliness of water and/or the condition of the water being studied. Factors that used to describe water quality are pH, Dissolved Oxygen, Temperature, Turbidity, Nitrogen, Biological Oxygen Demand (BOD), Fecal Coliform, Phosphate, and Total Solids. Water quality is important to know because water is a necessary part of life, and people need to know how clean the water they’re using is. Water quality is important for…

  • Essay On Chesapeake Bay

    The Catholic Church teaches seven principles of social teaching, and in those teachings are the dignity of a human being, call to a particular group or family and to participate, rights and responsibilities, giving to the wellbeing of the poor, dignity and rights of workers, solidarity, and lastly care for god’s creation. The Chesapeake Bay has been degraded by pollution, manmade and natural change over the course of many years. But many young adults can make a change and help out by taking part…

  • Pennsylvania Jackfork Group Analysis

    The mud matrix in the massive sandstone facies ranges from 3 - 25%. The published petrographic data and the thin section study indicate the section ranges between 10 - 25% and are mostly primary matrix. If the sandstone beds were deposited from turbulent suspension or turbidity currents they would have developed normal grading and gradational upper contacts with higher amounts of matrix near the top of the bed, but gradational upper contacts are absent. The Jackfork is composed predominately of…

  • Essay On Turbidity In Water

    Water temperature increases as the turbidity increase. This is caused by the absorbance of heat by the suspended particles within the water body. This reduces the concentration of dissolved oxygen (DO) in the water since warm water holds less DO compared to cold water. Higher turbidity also reduces the amount of light that can penetrate the water, which reduces photosynthesis and the production of DO. Based on Wetzel and Likens (2000), turbidity in water is caused by suspended inorganic and…

  • Turbidity In Freshwater Creek

    potential factors including either from the dispersion of suspended solids that have been exploited throughout the body of water. Apart from the dirt and other inorganic substances, (including nitrates and phosphates, which have made their way into the water system through fertilizers and detergents from nearby parks and farm properties), there has also been evidence suggesting there has been significant amounts of bacteria, that of which has been distributed throughout the system through…

  • Turbidity Of Water Macroinvertebrates

    Turbidity is a reflection of the amount of fine suspended sediments in the water, which was what affected Site 2’s turbidity. Conductivity can affect organisms as high conductivity can encourage algae which can lead to daily fluctuations in both pH and dissolved oxygen levels which are harmful to organisms living in the water. Although site 3 had high conductivity, we can’t be 100% sure as to whether it was affected by the tide. Our methods were valid as it tested the hypothesis and got a…

  • The Importance Of Turbidity And Atomic Spectroscopy

    Turbidity: - Turbidity is a degree of water clarity. Turbidity is defined as an “expression of the optical property that causes light to be scattered and absorbed rather than transmitted in straight lines through the sample”. Nephelometers are used to measure the intensity of light scattered by contaminants present in water such as suspended and colloidal solids like clay, silt and microscopic organisms. Turbidimeters using the principle of nephelometer compare the light scattered due to…
