The U.S. Environmental Protection Agency’s drinking water standards published in 2024 for six PFAS were calculated to provide nationwide health benefits due to concurrent reduction in PFAS as well as total trihalomethanes (TTHMs or THM4), a group of carcinogenic disinfection byproducts. Here, we present a disinfection byproduct case study analysis of 19 community water systems that installed treatment to remove PFAS between 2018 and 2022. Fifteen case study systems observed reductions in THM4, and 15 observed reductions in haloacetic acids (HAA5) following the installation of PFAS treatment. Average reductions were 42% for THM4 (range: 9%–95%) and 50% for HAA5 (range: 2%–97%).

This perspective explores the role of FLP, including free-living amoebae (FLA), in promoting AMR with a focus on wastewater treatment plants (WWTPs), recognized hotspots for the release of AMR. Technological advances in WWTPs have changed ecological niches, impacting their microbial communities. Each process alters the diversity, abundance, and activity of FLP/FLA and bacteria, generally increasing the potential for horizontal gene transfer of antibiotic resistance genes (ARGs). Further, disinfection treatments such as chlorination, UV irradiation, and ozonation may inadvertently select for antibiotic-resistant bacteria (ARB) and multidrug resistance through natural stress responses, which are also enhanced and protected within FLP. Overall, there is a critical need to better understand the ecological impacts of biological wastewater treatment technologies and their associated interactions between FLP/FLA and ARB, and their pathways of AMR dissemination through engineered and natural water systems.

While no single method was optimal for all targets, combining HA filtration and solid methods in parallel for the same sample is recommended to sensitively detect viruses, bacteria, and fungal pathogens.

This study characterized the occurrence of 77 PFAS compounds in raw and treated water from 15 drinking water treatment plants (WTPs) in the Greater Montreal Area, including an urban creek receiving airport runoff. A total of 32 compounds were detected at least once, representing diverse classes and carbon chain lengths. This helped to identify trends and precursor impacts on the PFAS profiles. Perfluoroalkyl carboxylic acids (PFCA) and perfluoroalkyl sulfonic acids (PFSA) were the most frequently detected. The highest concentrations occurred in WTPs drawing from the St. Lawrence River, while the Ottawa and L’Assomption Rivers demonstrated the occurrence of localized contamination. Conventional treatment showed negligible PFAS removal. WTPs drawn from the same water source were generally correlated. Correlation analyses also demonstrated that some plants are influenced by both the Ottawa and St. Lawrence Rivers. Airport-related PFAS compounds, such as those from aqueous firefighting foam and hydraulic fluids, were detected in downstream WTPs. Seasonal trends suggest that temperature and flow variations might affect PFAS concentrations.
