Perfluoroalkyl and Polyfluoroalkyl Substances in Groundwater Used as a Source of Drinking Water in the Eastern United States

Peter B. McMahon et al.

Summary: This study evaluated the occurrence of perfluoroalkyl and polyfluoroalkyl substances (PFAS) in groundwater used as a source of drinking water in the eastern United States. The results showed that 14 out of 24 PFAS were detected in the groundwater samples, with at least one PFAS detection found in 60% of public-supply wells and 20% of domestic wells. The study also identified several factors that were significantly associated with PFAS detections, such as tritium concentration, urban land use, and VOC and pharmaceutical concentrations.

Per- and polyfluoroalkyl substances in the environment

Marina G. Evich et al.

Summary: PFAS has become a symbol of environmental contamination, attracting public, scientific, and regulatory concern. These compounds are globally distributed through atmospheric and aqueous releases, and they accumulate in biota through multiple pathways. Efforts to remediate PFAS-contaminated matrices are still in their early stages, with a focus on research targeting drinking water.

Temporal trends of perfluoroalkyl substances in an Australian wastewa-ter treatment plant: A ten-year retrospective investigation

C. Gallen et al.

Summary: PFAS are problematic chemicals detected in wastewater due to daily product usage. Actions have been taken since 2000 to limit their manufacture and usage. A study conducted in an Australian urban population from 2010 to 2020 showed a decline in PFAS concentrations, highlighting the longterm consequences of their use in products.

Application of native plants in constructed floating wetlands as a passive remediation approach for PFAS-impacted surface water

John Awad et al.

Summary: Strategies for remediating per- and polyfluoroalkyl substances (PFAS) often focus on highly contaminated areas, but PFAS mobility leads to widespread low-level contamination. Constructed Floating Wetlands (CFWs) promote plant growth in buoyant structures, assimilating pollutants. This study found that CFWs could potentially reduce PFAS contaminants in surface waters.

Perfluoroalkyl substances in marine food webs from South China Sea: Trophic transfer and human exposure implication

Jieyi Diao et al.

Summary: The study investigates PFASs in the South China Sea, and suggests that short-chain PFASs have been used as substitutes for long-chain PFASs in recent years. PFOS has biomagnification potential in the marine food web. PFASs consumed through seafood consumption do not pose significant health risks to local residents.

Perfluoroalkyl Substances (PFASs) in Fish from European Lakes: Current Contamination Status, Sources, and Perspectives for Monitoring

Sara Valsecchi et al.

Summary: The study analyzed the concentrations of perfluorocarboxylic and perfluorosulfonic acids in fish from several lakes in the European subalpine area. The results suggest that PFAS contamination in lake fish is generally correlated with the degree of urbanization of the lake catchment, and the possibility of harmonizing monitoring protocols was tested.

Extending the knowledge about PFAS bioaccumulation factors for agricultural plants - A review

Lukas Lesmeister et al.

Summary: The main source of PFASs in agricultural plants is their uptake from contaminated soil. A comprehensive review of >4500 soil-to-plant BAFs for 45 PFASs from 24 studies involving 27 genera of agricultural crops revealed that factors such as plant growth stage and type can significantly affect the transfer of PFASs, and the number of perfluorinated carbons absorbed by plants can impact the levels of BAFs.

Perfluoroalkyl substances (PFAS) in surface water and sediments from two urban watersheds in Nevada, USA

Xuelian Bai et al.

Summary: The study measured 17 PFAS in surface water and sediments from various locations in Nevada. Short-chain PFAS were more prevalent in water, while long-chain PFAS were more detectable in sediments. Las Vegas Wash water had significantly higher PFAS levels compared to water samples from the Truckee River.

Comparison of potential drinking water source contamination across one hundred US cities

Sean W. D. Turner et al.

Summary: In the U.S., most cities rely on surface water sources that include treated wastewater, with concentrations in the Midwest, South, and Texas. Potential contamination of drinking water supplies from local and distal source watersheds is a concern, as water quality sampling surveys are often inconsistent and incomplete. The diversity of anthropogenic activities across watersheds leads to disparities in potential contamination of drinking water supplies for large cities.

Three decades of trace element sediment contamination: The mining of governmental databases and the need to address hidden sources for clean and healthy seas

Jonathan Richir et al.

Summary: The study analyzed UK datasets spanning 31 years to assess the evolution of sediment pollution by trace elements. While overall trace element pollution showed a decrease in the 1980s followed by incremental improvements, there was a distinct increase in pollution in 2010-13. Certain elements showed low pollution levels, some moderate, and others remained temporally stable. However, there were increasing trends observed for some elements like Ni, Fe, and Cu.

Comparison of currently available PFAS remediation technologies in water: A review

Dushanthi M. Wanninayake

Summary: The remediation of PFASs in the environment is challenging due to limitations in field applications of existing techniques and the unique physiochemical characteristics of various PFASs. Advanced techniques such as electrochemical, sonochemical, AOPs, plasma, and novel hybrid techniques show promise for PFAS removal, but more research is needed to optimize their effectiveness in real-world scenarios.

Stuart L. Simpson et al.

Summary: Guideline values for PFOS in estuarine/marine sediments were derived based on water quality guideline values and data on toxicity to benthic biota. The study found that toxicity of PFOS was mainly attributed to dissolved exposure rather than dietary exposure. Field-collected sediment samples generally had PFOS levels below the screening value.

Summary: PFAS are widely used in consumer and industrial applications worldwide, with monitoring studies in WWTPs mainly focused on China, Europe, and North America. Short and long-chain perfluoroalkyl acids are widely detected in WWTP influents and effluents, with most WWTPs exhibiting low removal efficiencies for PFAS and biodegradation being the primary mechanism for PFAS transformation in WWTPs.
