Per- and polyfluoroalkyl substances (PFAS) are used in a large variety of industrial processes and are present in many common household items. As a result, PFAS are regularly introduced into the environment from a variety of sources. Many PFAS are present in wastewater treatment plant residuals and may contaminate soil, surface water, and groundwater following land application. Understanding the fate and transport of PFAS in soil is a critical step in assessing potential effects on human health and the environment. PFAS in soil and/or groundwater can enter the food chain through uptake by plants leading to potential exposure of human and ecological receptors. The general public is exposed to PFAS mostly through diet. PFAS have been detected in vegetables, fruits and grains in Europe and North America. Modeling the uptake and accumulation of PFAS in plants is therefore also important. PFAS fate and transport in the environment is complex and is influenced by many factors including hydrologic processes, soil properties, total organic carbon content, surface charge, soil and water pH, redox, PFAS concentrations, polyfluorinated compound transformation rates, and the structural features of individual PFAS. Therefore, selection of environmental fate and transport models suitable for predicting PFAS concentrations in leachate, and plants is quite challenging. In this study, we reviewed publicly available models that could potentially be used to predict PFAS concentrations in groundwater, and plants resulting from soil leaching. Each model reviewed was evaluated for: basic function; intended or most common usage; availability; and, applicability to PFAS. The models were then evaluated for their overall suitability to predict PFAS fate and transport through leaching process. This information can be used by various industries, municipalities, regulators and other stakeholders to: 1) select models for fate and transport of PFAS; 2) identify key parameters necessary to model PFAS fate and transport; 3) considerations for modeling; and, 4) describe information gaps to refine PFAS modeling. Dependence on PFAS chain length and functional groups is also discussed. The study also focuses on plant uptake modeling. Readily available, comprehensive plant uptake models have been developed mainly for neutral persistent organic pollutants. Simple models of bioaccumulation using soil to plant transfer factors for edible parts of plants or root vegetables can provide an estimate of PFAS concentrations in plants despite variability in uptake among plant species and in soil characteristics. In this study, literature-based soil to plant transfer factors were compiled for perfluoroalkyl carboxylic acids (PFCA) (C4 to C10) and perfluoroalkane sulfonic acids (PFSA) (C4, C6, C7, C8 and C10) for several types of crops and under various soil characteristics. Generic soil to plant transfer factors were derived in this study for several plant types including root vegetables, leafy vegetables, grains and fruits where data permitted. This can be used in environmental risks assessment for estimation of dietary exposure to PFAS. Dr. Nava Garisto, National Discipline Leader and Risk Group Manager, Arcadis Canada Inc. Dr. Nava Garisto is an internationally recognized risk expert. She is a National Discipline Leader and a Risk Group Manager at Arcadis Canada Inc. with 30 years of project experience managing large scale and complex environmental risk projects in Canada and internationally. Nava has developed human health and ecological risk assessments for a variety of industries and contaminated sites, including PFAS contaminated sites (airports, sludge-amended soils, industrial sites), nuclear generating stations and fuel refining and manufacturing and sites of potential future waste disposal, former refineries and municipal works. Nava has managed projects related to asset risk ranking, fate and transport modelling, geochemistry/hydrogeochemistry and spill risk assessment. She has developed risk estimates as strategic tools for making cost-effective risk-management decisions including recent projects on risk from releases to groundwater and the aquatic environment in both freshwater lakes and the marine environment. Nava participates, as a member of the Canadian Standards Association (CSA) N288 Committee, in the development of fate and transport models and plant uptake models for use in contaminated site risk assessment.
