Water Quality Research Literature Review: > Introduction: [work in progress] > Turbidity: Turbidity refers to how clear water is. Turbidity determines how far light can penetrate into water. Excess soil erosion, dissolved solids or excess growth of microorganisms are most commonly the causes of high turbidity. Because water with a high turbidity can impede light, plants under the water may die as a result. Dead plants will not only result in less oxygen but the organic matter will only contribute to the microorganisms thus diminishing the oxygen even further. No dissolved oxygen means that other aquatic life forms will not be able to live in the water (National Library of Medicine, n.d.). > Temperature: The temperature of water can have a great affect on the ecosystem. Some organisms like colder water, while others prefer warmer water. Most aquatic organisms are cold-blooded, which means that their body temperatures match the temperature of their surroundings. Changes in temperature can affect the body functions of these organisms. It is also important to know that when the temperature goes up, water will hold more dissolved solids, but fewer dissolved gases (including oxygen). The opposite is also true for colder water because plants and algae like to live in warmer water. Generally, bacteria will grow more rapidly in warm waters and oxygen will be more abundant in colder waters (National Library of Medicine, n.d.). > Dissolved Oxygen: Oxygen is important for the
