Aqueous Film-Forming Foam Concentrate (AFFF)¶
Aqueous film-forming foam (AFFF) concentrates are used for fire suppression, and the process alternatives considered for its management are shown in following figure. Currently included alternatives for AFFF include SCWO and deep well injection. Thermal treatment and solidification followed by landfill disposal are also potential treatment options that are not included in the current version of the SAT.
Aqueous Film-Forming Foam Concentrate Properties¶
Assumptions and Limitations¶
There are different formulations of AFFF that may have different material properties. Users should be aware of these potential discrepancies.
The SAT does not currently allow for AFFF to be thermally treated or solidified and subsequently disposed in a landfill. Since these are conventional management systems for AFFF concentrates, they would be beneficial to add to the SAT.

Construction and Demolition Waste (C_DWaste)¶
Construction and Demolition (C&D) waste is generated during the construction and demolition of buildings and other infrastructure. It includes a wide variety of waste components including for example, dirt, broken brick and concrete, wallboard, ceiling tile, lumber and other flooring materials, electrical wiring and conduit, plumbing pipes and fixtures, furniture, and carpet. The following figure shows the potential alternatives used to treat C&D waste. C&D waste can be disposed in a dedicated C&D landfill, in MSW landfills, or sometimes by thermal treatment for wastes with a sufficiently high proportion of combustible material The disposal of C&D waste in C&D landfills is potentially problematic as such landfills are often unlined based on prevailing state regulations. One source of PFAS in C&D waste is PFAS-treated carpet that has been shown to release PFAS in laboratory-scale landfill simulations.
Construction and Demolition Waste Properties¶
Assumptions and Limitations¶
C&D waste is a heterogeneous material, and it is therefore important to update the material properties when a different composition is being managed.
There are also limited PFAS concentration data on different materials in C&D. The PFAS concentrations were measured using extractions and leaching tests and may be biased low due to the presence of PFAS that was not released to the aqueous phase in the test. If additional data on PFAS concentrations in C&D materials becomes available, then the default can be readily updated.

Combustion Residuals (Thermal Treatment Residuals)¶
Combustion residuals are produced during thermal processing and may include bottom ash, fly ash, and air pollution control (APC) residues. APC residues may include excess lime, reaction products in wet scrubber sludge, activated carbon, and gypsum. In the US, fly ash and bottom ash are typically combined and disposed in a dedicated ash landfill or in an MSW landfill. If a dry APC system is used, then the lime and salts or other residues may be added to this ash as well.
Combustion Residuals Properties¶
Assumptions and Limitations¶
The default modeling properties associated with combustion residuals are not currently responsive to the initial feedstocks and the type and operation of the facility (e.g., boiler type, APC system). There is currently little data on the actual disposition of PFAS entering combustion facilities including potential transformations and mineralization.

Compost¶
Finished compost (i.e., the product) is produced in the composting process. The treatment/management alternatives for finished compost are shown in the following figure. High quality compost may be land applied, but compost may also be used in landfills as alternative daily cover. Landfilling of compost typically occurs because of high contamination rates, a lack of local markets as well as demand from landfills that sometimes need substitutes for soil as a daily cover.
Compost Properties¶
There is currently limited data on PFAS in compost and given the large range of potential feedstocks and processes, the values for any specific compost are likely to vary significantly from the default data. The presence of PFAS in finished compost may be attributable to the presence of PFAS on various types of food packaging though further study is required to definitively prove this. Biosolids, if a feedstock for the composting process, are another potentially major contributor to PFAS to finished compost. #### Assumptions and Limitations: The default modeling properties associated with finished compost are not currently responsive to the initial feedstocks and the type and operation of the composting facility (e.g., windrows, mixed systems, Gore systems). With existing data, it is possible to create a mechanistic model for bulk density, solids content, and organic C content, but due to the limited amount of PFAS-related data on compost, it is not currently possible to develop a model that could reasonably estimate PFAS concentrations and partition coefficients mechanistically from incoming feedstocks.

Contaminated Soil¶
Soils may become contaminated with PFAS through a variety of processes including AFFF application, or land application of PFAS-contaminated compost or biosolids. The following figure shows the treatment alternatives considered for the management of PFAS-contaminated soils. The soils may be stabilized in place, sent to thermal treatment, or disposed in a landfill. Given the wide range of types of potential contaminated soil, default values were not developed. To assess contaminated soil, the user needs to provide the necessary material properties. The contaminated material is meant to represent a general contaminated soil that the user can specify.
Contaminated Soil Properties¶
Assumptions and Limitations¶
The PFAS concentration and properties of contaminated soil will vary based on the location, soil, type, local hydrology, and how the soil became contaminated. Thus, some user knowledge is important to properly represent this waste stream.

Contaminated Water¶
Water may become contaminated with PFAS through a variety of processes including direct releases, AFFF application, or land application of PFAS-contaminated compost or biosolids. The following figure shows that the water may be directly injected into deep wells or treated in conventional or advanced wastewater treatment processes. Given the wide range of types of potential contaminated water, default values were not developed. To assess contaminated water, the user needs to provide the necessary material properties. However, landfill leachate and primary and secondary WWT effluent are described in their respective sections. The contaminated water material is meant to represent a general contaminated water stream.

Assumptions and Limitations¶
The PFAS concentration and properties of contaminated vary based on the source. Thus, some user knowledge is important to properly represent this waste stream.

Food Waste¶
The management alternatives considered for food waste are shown in the following figure. This material can remain in the mixed MSW and be landfilled or incinerated, or it can be separated and composted or treated by anaerobic digestion (AD).
Food Waste Properties¶
PFAS has not been measured directly in the organic fraction of MSW, but it has been found in both food packaging and finished compost, so it would be expected to be in these feedstocks as well (Kotthoff et al., 2015; Choi et al., 2019; Lazcano et al., 2020). Food waste represents a large range of materials (e.g., vegetables, meats, coffee grounds, shells) from a variety of sources (e.g., residential, commercial, and industrial). The properties (e.g., solids content, C content, nutrient content) of these different types of food can vary considerably, and they each have different probabilities of being contaminated with PFAS. The heterogeneity of food waste makes it difficult to develop generalized default inputs.
Assumptions and Limitations¶
Food waste is heterogeneous, and the current data set does not consider how changes in food waste composition will impact its physical properties and PFAS concentrations. There is also limited PFAS concentration data on food waste.
Default data are based on the Netherlands and may not be representative of U.S. food waste. The concentrations provided by Noorlander et al. (2011) could be applied to U.S. dietary intake to improve the results.

Landfill Leachate¶
PFAS-contaminated landfill leachate is produced through the release and leaching of PFAS from materials disposed in landfills. The following figure shows the alternatives that are considered for the treatment of landfill leachate. The leachate may be treated by on- or off-site WWT, or it may be injected into deep wells.
Landfill Leachate Properties¶
The default values represent wet, temperate, and arid landfills with waste of different ages. If the user is modeling landfill leachate, then it is recommended that they use values that are representative of their specific facility and location where available. The properties of landfill leachate will vary based on things like the type of waste accepted and the waste age.

Municipal Solid Waste (MSW)¶
MSW consists of wastes that are typically managed by municipalities and counties and include waste generated from residential, commercial, industrial (excluding process waste), and institutional sources. The following figure shows the alternatives considered for the management of MSW. The MSW may be landfilled or thermally treated. MSW consists of variety of different materials including food, paper, food packaging, textiles, and plastics with different material properties and the potential to contain different amounts and types of PFAS.
MSW Properties¶
Assumptions and Limitations¶
MSW is a heterogeneous material and it is therefore important to update the material properties when a different composition of MSW is being managed.
There is limited PFAS concentration data on different materials in MSW. The PFAS concentrations for carpets and rugs, food, textiles and bulky concentrations were measured using extractions and leaching tests and may be biased low due to the presence of PFAS that was not released to the aqueous phase in the test. If additional data on PFAS concentrations in MSW materials becomes available, then the default data can be updated.

RO Concentrate¶
RO concentrate is produced from RO systems that are used to remove PFAS and other contaminants during the treatment of contaminated water. The following figure shows the potential treatment alternatives for RO concentrate. This material may be directly released to surface water, disposed in a landfill after mixing to absorb free liquid, treated in a WWT plant, injected into a deep well, or treated through supercritical water oxidation (SCWO).
RO Concentrate Properties¶
Assumptions and Limitations¶
The PFAS concentration in RO concentrate will vary based on PFAS concentrations in the water stream being treated and the recovery, at which the process operates. Thus, some user knowledge is important to properly represent this waste stream.

Spent GAC¶
PFAS-laden spent granular activated carbon (GAC) is generated when GAC adsorption processes are used to treat water contaminated with PFAS. The following figure shows the management alternatives considered for spent GAC. The GAC can be landfilled, combusted, or thermally reactivated to generate GAC that can be reused for contaminant removal.
Spent GAC Properties¶
Assumptions and Limitations¶
The PFAS concentration in GAC will vary based on PFAS concentrations in the water stream being treated. Thus, some user knowledge is important to properly represent this waste stream.
The default concentrations are based on isotherm data at specified equilibrium concentration of 100 ng/L. These concentrations will vary under different conditions and using site-specific data will be beneficial.

WWT Effluent¶
The following figure shows the treatment alternatives that were considered for primary and secondary wastewater effluent. The effluent can either be released to surface water or sent to advanced physico-chemical treatment (advance WWT) for PFAS removal.
WWT Effluent Properties¶
Existing data on PFAS in wastewater shows that the PFAS concentration will vary between treatment plants based on the source water properties, possible upstream contaminants, and potential treatment options. Therefore, if WWT effluent is the starting material in an analysis it is best for the user to understand the properties of their specific stream to improve their results.
Assumptions and Limitations¶
While there is data on PFAS in WWT influent and effluent, more research is needed on the fate of PFAS entering WWTPs including their potential transformations.
