In the testing stream water there will be nitrates, phosphates, dissolved oxygen, turbidity, different temperatures, and pH levels.The most important factor to stream testing is the temperature of the water. If the temperature increases the amount of dissolved oxygen decreases. (EPA and Staff, 2012)Phosphates are present in the water through human and animal wastes. (Oram, no date) Phosphates are used in laundry soaps, cleaners, industrial effluents, and fertilizers. (Oram, no date) Nitrates are used in fertilizers, rodenticides, and food preservatives.Turbidity is caused by sediment or other pollutants and causes the water to appear murky or cloudy. (2008) The pH can be changed by some of the rocks in the water, such as limestone which neutralizes …show more content…
Phosphates get into the by lawn and landscape fertilizers . (Pond or Lake Water Chemistry, no date) Phosphates are present in the environment in low concentrations and limits plant growth. Phosphate is an inorganic chemical is a salt of phosphoric acid. Erosion and bank runoff causes phosphates to get into the water. Phosphate levels should not exceed 0.05 mg/L. ([Envir Sci Inquiry] Lehigh River Watershed Explorations, no date) The dissolved oxygen testing should be done on site. If dissolved oxygen levels drop below 5.0 m/L the aquatic life will be under stress. If oxygen levels stay below 1-2 m/L it could cause a big fish killing. (Dissolved Oxygen and Water Quality, no date) If the dissolved oxygen levels are too low or too high the dissolved oxygen could harm aquatic life and water quality. Dissolved oxygen is necessary for many types of fish. Air gets into the water by the diffusion of surrounding air. and plant byproduct is the way dissolved oxygen gets into the water. (Dissolved Oxygen - Environmental Measurement Systems, no …show more content…
Stream temperature can cause increase in an organism’s metabolic rate. Stream temperature increases the amount of dissolved oxygen. Temperature is a major influence on biological activity and growth. Organisms that can live in rivers or lakes need the temperature to be steady. Temperature is important to water chemistry. (Perlman and USGS, no date) The cutting down of trees will expose the water source to more sunlight which will increase the temperature. Stormwater runoff can make the water temperature increase. Turbidity can increase the temperature of the water too. (Water Quality Monitoring: Temperature Change, no
