In this lab, we participated in many tasks that described the water quality of the Chippewa River. Some of us collected data for three parameters that describe the water quality: macro invertebrates, habitat quality, and water chemistry. Under water chemistry, we collected the waters dissolved oxygen, nitrogen and phosphorus, and pH levels. The group with habitat quality assessed the waters velocity, temperature, water depth, discharge, riparian vegetation, and substrates. My group studied the micro invertebrates that lived in the Chippewa River. All of these factors that we tested contributes to the waters quality and to the surrounding environments.

pH is a determined value based on a defined scale. pH of water is not a physical parameter that can be measured as a concentration or in a quantity. It is a number between 0 and 14 defining how acidic or basic a body of water is along a logarithmic scale. The lower the number, the more acidic, the higher the number, the more basic the water is. A pH of 7 is considered neutral (Merriam Webster). The pH values run on logarithmic scale. This means that each number below 7 is 10 times more acidic than the previous number when counting down and the opposite with pH levels are above 7. This is due to the effect of hydrogen ions and hydroxyl ions on pH. The higher the hydrogen ion concentration, the lower the pH, and the higher the hydroxyl concentration, the higher the pH. Hydrogen and hydroxyl ions work in pairs, so as the…
