This Project Grant award, valued at $620,000.00, was provided by the National Science Foundation (NSF) through its Mathematical and Physical Sciences Federal Grant Program (CFDA 47.049). The award, titled "CAS-MNP: IMPACT OF DISINFECTANTS ON RELEASE AND TRANSFORMATION OF MICROPLASTICS AND ADDITIVES FROM DRINKING WATER PIPES," aims to investigate the effects of free chlorine, a common disinfectant used in drinking water distribution systems, on plastic pipes. This research, conducted by professors and students from Johns Hopkins University, the Colorado School of Mines, and their collaborators, will synthesize model pipe materials and expose them to model drinking water to quantify any microplastics formed and analyze the leaching of chemical additives. The project intends to develop a comprehensive safety profile of polyvinyl chloride (PVC) and polyethylene (PE) pipes under oxidizing conditions, with the goal of informing the health and safety impacts of plastic pipes in drinking water systems. The award has a period of performance from June 15, 2025, to May 31, 2028.
