This research focused on two sites selected for water quality monitoring along Ecorse Creek in the southern portion of Dearborn Heights, Michigan just outside of the Metropolitan Detroit area. These sites are located within nearby residential areas and located upstream of an urbanized region. The first site is located near a city recreational center and the second site is located in a light industrial and residential area. Water quality parameters tested in this research included nitrates, dissolved oxygen, phosphates, E-coli, and temperature. All data was collected following GLOBE protocols when applicable. Data collection began during August 2024 and continued until early-December. Data was then interpreted and compared to previous data collection from July 2023 to August 2023. Researchers found that as precipitation levels increased, so did the amounts of dissolved oxygen. Additionally, there was a correlation between precipitation and phosphates, with both parameters significantly increasing after the storm, affecting the quality of the Ecorse Creek. The variables tested resulted in notable correlations, demonstrating how environmental factors interact to influence water quality. The researchers extended their research to include additional water quality parameters beyond the GLOBE protocols used. Looking ahead, they hope to further expand their study by collaborating with the Dearborn Heights Steward Watershed Commission to discuss their data and gather input on environmental protection efforts.
