“…Currently, the technologies for treating water are limited and often expensive. These technologies largely rely on separation technologies for removing the PFAS from the water (Crone et al 2019; US Environmental Protection Agency 2019c). In addition to being able to treat the wide range of PFAS present in AFFF formulations, treatment technologies must also be able to remove and/or destroy PFAA precursors such as the fluorotelomer sulfonates.…”

The use of aqueous film-forming foam (AFFF) has resulted in the widespread occurrence of per-and polyfluoroalkyl substances (PFAS) in groundwater, drinking water, soils, sediments, and receiving waters throughout the United States and other countries. We present the research and development efforts to date by the Strategic Environmental Research and Development Program (SERDP) and the Environmental Security Technology Certification Program (ESTCP) to measure PFAS in the environment, characterize AFFF-associated sources of PFAS, understand PFAS fate and behavior in the environment, assess the risk to ecological receptors, develop in situ and ex situ treatment technologies for groundwater, treat soils and investigation-derived wastes, and examine the ecotoxicity of PFAS-free fire suppression formulations.

“…Due to their amphiphilic properties, and preferential binding to proteins, PFAS have been found to be the most prevalent contaminants in human blood (Kannan et al 2004) and wildlife worldwide (Keller et al 2005;Francis et al 2008;Quinete et al 2009), presenting clear potential hazards to human health. Human exposure to PFAS can occur through food and water ingestion, dust inhalation, and hand-to-mouth transfer from contaminated area (Crone et al 2019;Sunderland et al 2019). Studies have shown that human PFAS exposure has been linked to elevated cholesterol, obesity, cancer, developmental delays, thyroid disease, and infertility and immune suppression in children (Ganesan and Vasudevan 2015;Pennings et al 2016;Sunderland et al 2019).…”

The current coronavirus pandemic is leading to significant impacts on the planet, changing our way of life. Although the COVID-19 virus mechanisms of action and pathogenesis are still under extensive research, immune system effects are evident, leading, in many cases, to respiratory distress. Although apparent pollution reduction has been noticed by the population, environmental and human health impacts due to the increased use of plastic waste and disinfectants is concerning. One of the main routes of human exposure to pollutants is through drinking water. Thus, this point of view discusses some major contaminants in drinking water known to be immunotoxic, exploring sources and drinking water routes and emphasizing the known mechanisms of action that could likely compromise the effective immune response of humans, particularly raising concerns regarding people exposed to the COVID-19 virus. Based on a literature review, metals, plastic components, plasticizers, and per-and polyfluoroalkyl substances may display the potential to exacerbate COVID-19 respiratory symptoms, although epidemiological studies are still required to confirm the synergistic effects between these pollutants and the virus.

“…Due in part to their lower molecular weight, nonpolymer PFAS are more likely to occur in water and air, which leads to their mobility and distribution distant from their point of manufacture, use, or disposal. For example, some of the nonpolymer perfluoroalkyl substances, like PFAAs, exist in their anionic form in water under environmental conditions, making them soluble and mobile in that matrix as demonstrated by their detection in surface water, groundwater, and drinking water (Ahrens and Bundschuh 2014; Chen et al 2018; Crone et al 2019; Gewurtz et al 2019). In addition, per‐ and polyfluorinated substances, especially acids, telomers (acids and alcohols), amides, and amidoethanols, have been measured in the air where they are primarily associated with particles and aerosols (Barton et al 2006; Chen et al 2018; Wang et al 2018; Han et al 2019).…”

Organic fluorinated compounds have been detected in various environmental media and biota. Some of these compounds are regulated locally (e.g., perfluorononanoic acid maximum contaminant level in drinking water by the New Jersey Dept. of Environmental Protection), nationally (e.g., perfluorooctanoic acid maximum acceptable concentration in drinking water by Health Canada), or internationally (e.g., Stockholm Convention on Persistent Organic Pollutants). Globally, regulators and researchers seek to identify the organic fluorinated compounds associated with potential adverse effects, bioaccumulation, mobility, and persistence to manage their risks, and, to understand the beneficial attributes they bring to products such as first responder gear, etc. Clarity is needed to determine the best analytical method for the goal of the analyses (e.g., pure research or analysis to determine the extent of an accidental release, monitoring groundwater for specific compounds to determine regulatory compliance, and establish baseline levels in a river of organic fluorinated substances associated with human health risk prior to a clean‐up effort). Analytical techniques that identify organic fluorine coupled together with targeted chemical analysis will yield information sufficient to identify public health or environmental hazards.
