Microplastics in Drinking Water Distribution Systems

This project aims to investigate the presence, behavior, and transformation of microplastics from source water through drinking water treatment and into distribution systems. By analyzing samples from multiple utilities across North America, the research will assess how factors like pipe material and water age affect microplastic concentrations and characteristics. Advanced analytical techniques, including Raman spectroscopy, will be used to characterize particles as small as 1 µm. The findings will support the development of practical monitoring strategies and provide data to inform future regulatory and utility decision-making. This study complements prior WRF research by shifting the focus beyond treatment to what consumers receive at the tap.
