This research examined the impact of a wastewater treatment plant on microplastic accumulation by comparing concentrations at two sites in the Detroit, Michigan area: Ford Field Park and Goudy Park. Ford Field, situated downstream of the wastewater treatment plant, offers insight into how proximity to waste water discharge influences microplastic levels. In contrast, Goudy Park offers insight into how urban areas affect microplastic levels. Over a four-month period, a total of 14 water samples were collected, one from each site per sampling session. GLOBE protocols such as water temperature, air temperature, conductivity, turbidity and total solids were measured using Vernier sensors, Hach 2100N turbidimeter, Hach utility oven, and the Ohaus Pioneer analytical balance. The data suggests variations in microplastic concentrations between the two sites, with potential influences from wastewater discharge. This research study found microplastic concentrations were higher near locations of industrialization and factories. While there was not enough data to draw concrete conclusions between the relationship between microplastic quantities and GLOBE hydrological parameters, there was an inverse relationship between total solids and microplastic concentrations. This research contributes to understanding the role of wastewater discharge in freshwater ecosystems and supports the development of effective pollution management strategies. Further analysis will be necessary to create definite conclusions about the long-term impact of wastewater treatment plant discharge on microplastic accumulation.
