The Technical Review Workgroup (TRW) Bioavailability Committee recently published the "Guidance for Sample Collection for In Vitro Bioaccessibility Assay for Arsenic and Lead in Soil and Applications of Relative Bioavailability Data in Human Health Risk Assessment." This is an update to the 2015 Guidance for Sample Collection for In Vitro Bioaccessibility Assay for Lead (Pb) in Soil. The update is intended to help EPA risk assessors, remedial project managers, and on-scene coordinators develop and use bioavailability data at their sites. It incorporates sample planning and data analysis recommendations from EPA's Guidance on Systematic Planning Using the Data Quality Objectives Process that are pertinent to sampling for In Vitro Bioaccessibility (IVBA) and Relative Bioavailability (RBA). It also clarifies the application of IVBA and RBA data to human health risk assessment, the development of risk-based goals at CERCLA remedial and removal sites and includes arsenic (As) which was recently added to the In Vitro Bioaccessibility Assay.

The TRW has developed a series of trainings based on the updated guidance. This session will focus on a discussion of soil sample collection and processing best practices and methods to directly measure relative bioavailability (RBA) or estimate RBA by measuring in vitro bioaccessibility via EPA Method 1340 at soil arsenic and lead contaminated sites.  This training will target a general audience of regional staff working in risk assessment, remediation, emergency response, technical support, and quality assurance. The training will be an approximately one hour long and will include time for general discussion. Members of the Bioavailability Committee and a Regional representative will be present to answer questions in real time.

Community Involvement at Federal Facilities is a two-hour webinar course that focuses on community involvement requirements, resources, and techniques available for Federal Facilities being cleaned up at National Priorities List (NPL) sites under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). By taking the course, participants will achieve the following objectives:Learn about community involvement requirements under CERCLA;Understand the roles of the lead federal agency and the Environmental Protection Agency (EPA) in public involvement at Federal Facilities;Discover resources and tools available for community involvement activities;Explore community involvement techniques and approaches that can be used at Superfund sites; and,Identify community involvement opportunities throughout the Superfund process at Federal Facilities.The instructional methodology for this course includes lecture, case studies, and group discussions. The target audience for this course is federal, state, and tribal representatives who work on Federal Facility cleanups. Ideally, students should have a basic understanding of the CERCLA process. This course is part of the Federal Facilities Academy training program. Please consider registering for other Federal Facility Academy courses and obtain a certificate upon completion of the entire Federal Facility Academy series (12 courses total).

The TRW has developed a series of trainings based on the updated guidance. This session will focus on a discussion of soil sample planning and data evaluation to assess confidence in site assessment and remediation decisions at soil arsenic & lead contaminated sites. EPAs new bioavailability sampling guidance tool will also be presented.  This training will target a general audience of regional staff working in risk assessment, remediation, emergency response, technical support, and quality assurance. The training will be an approximately one and half hours long and will include time for general discussion. Members of the Bioavailability Committee and a Regional representative will be present to answer questions in real time.

This webinar will include live deliveries of two presentations from the recent FRTR Fall meeting, with updated information:
"Best Practices for PFAS Sampling and Evaluation"
"Clean Water Act Methods: Overview of EPA's CWA PFAS Method Activities".

The science and technology of site characterization for per-and polyfluoroalkyl substances (PFAS) has advanced in the five years since FRTR last addressed the topic in 2018. Federal agency budgets for PFAS remediation have grown substantially during this time. As a result, site characterization efforts such as Remedial Investigations, as well as early response actions, are underway at many Federal facilities. Funding for field-scale projects to further advance PFAS characterization technology and methodologies also has increased substantially.

This webinar will allow PFAS member agencies to share results of recent and on-going PFAS projects that are improving our understanding of PFAS characterization technologies.
