Alkalinity+Project

Kristina, Mary, Corey, and Evan

Our assigned task was testing the Alkalinity in the water at Mashamoquet. In this project summary Kristina was in charge of typing the information and data along with collecting the information. Mary was in charge of gathering data while Corey and Evan are responsible for presenting. Kristina and Mary conducted three tests all of which had a stable 20.6 ppm. While Evan and Corey conducted two tests one with a PH level of 20.6 ppm and one with a PH level of 40 ppm. The alkalinity of fresh waters is typically between 20 and 200 mg/l. In CT, alkalinity values are generally well below 100 mg/l. The pH of water does not decline steadily with acid contamination. Buffering minerals moderate the decline to around pH 6.4. Below pH 5.5 very little buffering materials remain and the pH declines rapidly upon addition of acid. At about pH 4.5, the buffering capacity of the water is lost. A negative PH level would be either too low or too high. The levels found at Mashamoquet were border line for fresh water, meaning it is safe enough for aquatic animals.

Alkalinity in the water helps the water buffer any acids that may enter the water. The higher the alkalinity the more acid the water is able to absorb. For more info, click on OTHER RESOURCES/ CT PROJECT SEARCH --> Publications, CHAP 7 Chemical parameters.
