AFFF PFAS Aquatic Ecological Risk Model Tool User's Manual
[Technical Report, Manual]
Pagination or Media Count:
This document is a users manual for the customizable Microsoft ExcelTM food web and wildlife exposure modeling tool Model Tool for assessing the potential ecological risks associated with exposure to perfluoroalkyl and polyfluoroalkyl substances PFAS for common and threatened and endangered T and E species in aquatic habitats potentially impacted by aqueous film forming foam AFFF1. The Model Tool a multi-worksheet ExcelTM file enables ecological risk assessors to enter site-specific data e.g., concentrations of PFAS in sediment, water, andor biota, exposure factors for site-relevant wildlife species of interest, and available toxicological information for common PFAS. Model outputs consist of an evaluation of the potential for direct effects to aquatic communities, as well as model predicted concentrations of PFAS in food webs and wildlife diet items. The model also feature stables that provide ecological risk assessment ERA effects assessment and risk characterization i.e., hazard quotients and other useful information that can facilitate ERA-based decision making.
