SWEDISH FOOD AGENCY 15/06/20 PFAS in drinking water and fish - risk management. In some cases, contamination following fire-fighting training using highly fluorinated firefighting foams has led to high concentrations of many different PFAS in ground water and private wells.
The SFA’s recommendations on risk management measures are based on what was known about the presence of these substances in drinking water up until 2016. New information has been published about the occurrence and toxicity of different PFAS in aquatic environments, in both Sweden and abroad. Also, new risk assessments of PFOS, PFOA, PFNA and PFHxS from the EFSA were released at the beginning of 2020. The recommendations on measures for PFAS substances in drinking water will be revised after the EFSA opinion 2020 is established and decisions have been made on maximum limits for PFAS in the EU drinking water directive. SWEDISH FOOD AGENCY - PFAS in drinking water and fish - risk management. WILEY 12/03/18 Occurrence and behavior of per‐ and polyfluoroalkyl substances from aqueous film‐forming foam in groundwater systems.
Following the release of AFFF to the environment, PFAS are thought to be retained in the source zone and slowly migrate hydraulically downgradient with groundwater flow, as do most soluble groundwater contaminants.
However, there are a number of differences in the behavior of some PFAS when compared to more typical organic contaminants, like benzene and trichloroethene, that likely impact how this retention and migration works. PFOS, PFOA, and the other perfluorinated carboxylates and sulfonates are organic acids that have an ionic component that affects how they interact with the subsurface geochemistry. They also have surfactant qualities, which makes them prone to accumulate at interfaces and surfaces. They are extremely stable and resistant to degradation, allowing them to migrate long distances and remain in systems a long time. And there are often precursor compounds present in the system that can degrade to form compounds of interest from a toxicity and regulatory perspective.

International Journal of Environmental Analytical Chemistry 31/07/17 Analysis and validation of perfluorinated compounds in water, sediment and fish with LC-ESI–MS/MS. The analysis of perfluorinated compounds (PFCs) in environmental matrices is challenging, as the concentrations are generally low, but the risk of contamination is high.
Sample preparation is a critical step and it is necessary to minimise the possibility of contamination. In this study, we successfully applied and validated a modified ion pair extraction method to quantify PFCs in sediment and fish samples. A large volume injection method was validated and used to quantify PFCs in different water matrices. Isotope internal standard of every analyte was applied to correct matrix effects. The recoveries of the analytes were 92–106% for water matrix, 93–119% for fish matrix and 86–103% for soil matrix whereas the achieved limit of quantitation values were 1.3–14.9 ng/L for water, 0.19–0.28 μg/kg for fish and 0.14–0.41 for soil samples.

UNIVERSITY HILL (Greece) - 2014 - Removal of Perfluorinated Compounds From Water using Nanoscale Zero-Valent Iron. Perfluorinated Compounds (PFCs) are persistent micropollutants that have been detected in various environmental and biological matrices, worldwide.
During the last decade, these compounds have also been detected in municipal wastewater and tap water. Due to the stability of C-F bond, the application of biological and conventional physicochemical treatment methods does not seem to remove sufficient these compounds from water and wastewater. In the current study, the removal efficiency of four PFCs using three different types of nanoscale zero-valent iron (nZVI) was investigated. Influencing factors such as, initial pH solution, reaction temperature and nZVI dosage were also studied.
According to the results, target compounds were removed in the presence of chemically synthesized nZVI modified with Mg-aminoclay (MgAC) than under commercial iron powder and chemically synthesized uncoated nZVI, under the same experimental conditions.

EWG 15/01/09 Bush Moves to Okay Toxic Teflon Pollution in Tap Water. For Immediate Release: Thursday, January 15, 2009 Washington, D.C. - January 15, 2009 - In its final days, the Bush administration appears poised to issue an emergency health advisory for tap water polluted with the toxic Teflon chemical PFOA (perfluorooctanoic acid) effectively allowing a significant level of pollution and discouraging cleanup of PFOA contamination in tap water in at least 9 states, according to an analysis by Environmental Working Group (EWG).
The level of permissible PFOA contamination under the administration’s guidance would be 10 times higher than that allowed by the New Jersey Department of Environmental Protection, whose commissioner, Lisa Jackson has been tapped by incoming President Obama to run the U.S. Environmental Protection Agency (EPA). If the Bush administration advisory is allowed to stand, it could result in blood levels of PFOA in people nearly 10 times higher than the current average amounts.

ENVIRONNEMENT CANADA 10/02/14 Sulfonate de perfluorooctane (SPFO) dans les poissons et l’eau. Le sulfonate de perfluorooctane (SPFO) est exceptionnellement persistant, omniprésent dans l’environnement et susceptible d’être transporté sur de grandes distances. Il est préoccupant sur le plan écologique en raison de sa présence générale, de sa bioaccumulation, de sa persistance et de sa toxicité pour le développement, de son immunotoxicité et de son hépatotoxicité chez les animaux.
Les indicateurs sur le SPFO dans les poissons et l’eau déterminent si les concentrations de SPFO dans le tissu des poissons et l’eau dépassent celles définies dans les Recommandations fédérales pour la qualité de l’environnement (RFQE) provisoires. Ces recommandations sont des limites numériques établies en vertu du Plan de gestion des produits chimiques (PGPC) pour protéger les écosystèmes aquatiques.
Le SPFO est un polluant organique persistant (POP) et est considéré comme étant une substance chimique hautement prioritaire en vertu du Plan de gestion des produits chimiques. SPFO dans l’eau. ENVIRONNEMENT QUEBEC - 2012 - Les composés perfluorés dans les cours d’eau et l’eau potable du Québec méridional. ANSES 10/06/11 Composés perfluorés : une première campagne nationale de mesure dans les eaux. Chargée par le ministère de la Santé, d'établir un premier état des lieux national de la présence de composés perfluorés dans les eaux, l'Anses, via son laboratoire d'hydrologie de Nancy, publie ses résultats.
Les composés perfluorés sont une large famille de substances chimiques (plusieurs centaines de molécules), fabriquées depuis les années 50 qui sont utilisés dans de nombreuses applications industrielles et produits de consommation courante. Très persistants et résistants à la dégradation, ces composés sont retrouvés dans tous les compartiments de l'environnement et dans la chaine alimentaire. Parmi ces substances, le PFOA et le PFOS ont particulièrement été étudiés, car ils constituent des produits de dégradation ultime des composés perfluorés les plus utilisés. A l'heure actuelle, la toxicité de certains de ces composés pose question, certains d'entre eux étant notamment suspectés d'avoir des effets de perturbateurs endocriniens.
