EPA Tools and Resources Training Webinar Series
Free webinars typically held bimonthly on the first Thursday from 3:00-4:00 PM (ET).
EPA's Office of Research and Development (ORD) hosts this bimonthly public webinar series to provides in-depth overviews and step-by-step tutorials on popular EPA science-based models and tools. In addition, the EPA Tools and Resources Webinar Series translates EPA research and shares research resources and information that are useful, practical/applied and available to meet stakeholders' research needs.
NOTE: Attendees have the option of receiving a certificate of attendance. Acceptance of certificates is contingent on organization requirements—EPA cannot guarantee acceptance. Closed-captioned recordings of the webinars are provided below for later viewing and as a training resource; certificates cannot be provided for viewing webinar recordings. Webinar dates and topics are subject to change.

Chemical Transformation Simulator: To Predict PFAS Metabolites and Environmental Transformation Products
The Chemical Transformation Simulator (CTS) is a publicly available web-based application that predicts how organic chemicals will transform in environmental and biological systems. Traditional exposure and risk assessments for human-made organic chemicals have only focused on chemicals in their manufactured form, but it’s well known that many organic chemicals can be transformed in the environment. Organic chemicals can also be metabolized into new molecules when they are ingested by humans or ecological species. These transformation products may differ from the parent in toxicity and tendency to bioaccumulate or persist in the environment.
CTS Reaction Libraries predict the products that form from various environmental transformation processes. Reaction Libraries have recently been developed to predict transformations of Per- and Polyfluoroalkyl Substances (PFAS), based on PFAS transformation products and kinetics reported in peer-reviewed literature. The enhanced predictive capabilities of CTS can help states identify and anticipate potential PFAS metabolites and environmental transformation products to which humans and ecosystems may be exposed.
This training webinar will provide an overview of CTS, including a demonstration of the CTS workflows for predicting transformation pathways and physicochemical properties of organic chemicals. The presentation will also highlight how CTS predictions can help identify transformation products detected during nontargeted analysis of environmental samples, particularly for novel PFAS chemicals.
