Recently finalized United States Environmental Protection Agency (EPA) regulations on per- and poly fluoroalkyl substances (PFAS) are expected to require water utilities install more advanced treatment technologies achieve compliance. With the costs of these likely falling upon already financially vulnerable utilities, providers may be forced raise rates – rendering services unaffordable for consumers In this work, we use EPA-based PFAS compliance cost estimates model system size-specific distributions pre- post-compliance 364 in state Ohio assess their ability provide affordable drinking given new regulations. Utilizing EPA definitions, find that National Primary Drinking Water Regulation creates median income less than 0.5% systems. However, applying alternative metrics from literature, low-income households customers served by very small systems (due poor economies scale) emerge as disproportionately have water. On average, annual bills post-PFAS were nearly $200 greater relative large These results support concerns current methods underestimate affordability while raising questions about definition a regulatory context.

Organic pollutants like per- and polyfluoroalkyl substances (PFASs) exhibit persistence, bioaccumulation, resistance to degradation, high toxicity, garnering significant attention from scholars worldwide. To better address mitigate the environmental risks posed by PFASs, this paper employs bibliometric analysis examine literature on PFASs' concentrations collected in Web of Science (WoS) database between 2019 2024. The results show that overall trend pollution research is relatively stable increasing. In addition, study also summarizes status traditional PFASs across different media typical freshwater basins. It analyzes surface water, sediment, aquatic organisms, elucidating their distribution characteristics potential sources. While perfluorooctanoic acid (PFOA) perfluorooctane sulfonic (PFOS) levels water environments are declining annually, short-chain substitutes emerging as primary pollutants. Short-chain frequently detected whereas long-chain tend accumulate sediments. more likely concentrate protein-rich organs tissues. presence largely influenced human activities, such metal plating, fluoride industry development, industrial wastewater discharge. Currently, development China faces a complex dilemma, entangled policy legal constraints, production demands, use new alternatives, regulation restriction, creating vicious cycle. Breaking deadlock necessitates continuous active scientific particularly PFOS, with an emphasis detailed investigations sources sinks. Furthermore, ecological health risk assessments were conducted using Risk Quotient (RQ) Hazard (HQ) methods. Comprehensive comparison indicates (such PFOA) majority basins at low-risk level (RQ < 0.1 or HQ 0.2), PFOS some medium-risk (0.1 RQ 1), no basin high-risk level. adsorption removal approaches analyzed, revealing combination multiple treatment technologies novel integrated technology holds excellent prospects for PFASs.

The United States Environmental Protection Agency (US EPA) recently finalized the enforceable maximum contaminant levels for some per- and polyfluoroalkyl substances (PFAS) in drinking water which intends to substantially decrease their level it. Conventional processes full-scale treatment plants (DWTPs) are usually inefficient PFAS removal from source (i.e., groundwater surface water). There is an increasing interest investigating/evaluating advanced technologies PFAS-contaminated help generate a number of potential solutions this engineering design challenge/problem. While numerous excellent research studies have been carried out reported literature on efficiency several removing water, mostly at lab- pilot-scales, DWTP investigations still need further attention. This study reviews US EPA’s quality guidelines/regulations, remediation DWTPs. Then, it discusses configurations water) as well suggesting future directions. Further effect environmental factors (e.g., organic matter) removal, effective elimination short-chain real using cost-effective industrially applicable technologies, efficiency/performance trains including innovative long-term produce associated costs, cost reduction/minimization via process optimization interest.
