The process of eutrophication has been an environmental issue in bodies of water in a range of places, largely since the 1900s. Previous research showed that after the Industrial Revolution
more runoff occurred increasing nutrients in the water, leading to algae blooms. Algae blooms
cause a decrease in dissolved oxygen (DO) leading to population loss. This study looked at Spot
Pond and Ell Pond, both local to our school. This study used titration to measure DO levels from pond samples. The pond samples are enriched with Miracle-Gro and Borax. Miracle-Gro has a high nitrogen level which is associated with eutrophication. We found that the Miracle-Gro had a similar trend while the Borax had no pattern. In this study we found that different chemicals created differing results including different DO levels.
