The purpose of this project was to compare five different wastewater treatment facilities and their microplastic removal efficiency from treated wastewater. Another goal for this project was to determine if microplastics were entering the Monocacy River watershed in Maryland, United States. Influent, effluent, and sludge samples were collected from each facility and microplastics were extracted and microscopically examined. Microplastic particles were present in all 50 samples and microfibers under 1.0mm were most predominant. Millions of microplastic particles are entering the Monocacy River watershed from wastewater effluent and millions of microplastic particles are reentering the terrestrial environment as sludge either applied as fertilizer or deposited in landfills.en-USCollection
