Enviromental Science - Water Quality Parameters Movie Review

Enviromental Science - Water Quality Parameters - Movie Review Example However, group 3 found a turbidity value of 30 downstream and group 4 found a turbidity value of 40 upstream. Temperature – the temperature of the water in the stream is within the normal temperature range. Water is cooler upstream than downstream meaning that metabolism activities in the stream are in the normal range. Temperature also affects reproductive activities in the stream and life cycles in general. Dissolved oxygen – it is the mass of oxygen present in the water, and its units are parts per million (ppm) or milliliter per Liter. The average dissolved oxygen of 7ppm means that the mass of oxygen in the water is within the required range for aquatic life. The values of 5.6 ppm and 5.2 ppm for dissolved oxygen upstream and downstream respectively shows that oxygen levels are lower than average. The amount of dissolved oxygen may be affected by temperature, flow of water, aquatic plants and altitude. Percentage Saturation – the percentage saturation is 62.2% upstream and 59% down stream. This is an indication of high metabolic activities in the stream that result in the production of by-products that increase the saturation of salts in water. This is a key parameter that lowers the water quality in the stream. PH – the pH of water in the stream is extremely crucial. It affects the ecosystem and toxicity of the water. The average pH of water in a stream is 6 – 7. The pH of water in the stream is 8.05 upstream and 7.9 downstream. This pH levels are suitable for aquatic life in the stream. Phosphate (ppm) - phosphate is a limiting nutrient which means that it is in short supply compared to nitrogen. The stream has low phosphate values of 1.6 and 1.4 for upstream and downstream
