NARPM Presents…Stand and Deliver Effective Presentations - June 11 and July 10, 2019, 1:00PM-3:00PM EDT (17:00-19:00 GMT). This webinar will provide participants with guidelines on how to make better presentations to the public, their peers, or management. The webinar will help to improve your presentation skills and provide you with tools and techniques to be an interesting and effective presenter. The webinar is intended to help participants increase their comfort in public speaking, control and connect with their audience, handle audience participation, and ultimately deliver the message and take-away points of training courses they are planning to instruct. The webinar will teach participants how to manage nerves, voice, gestures, transitions, visual aids, and content. The webinar also addresses how to manage the audience to include difficult participants, the solicitation of questions, and the response to questions and will include techniques for adapting to diverse audiences.

Using Comprehensive Area-Wide Planning Approaches to Promote Equitable Development - June 18, 2019, 1:00PM-2:30PM EDT (17:00-18:30 GMT). Several decades of practice in environmental justice and community revitalization has resulted in comprehensive area-wide planning approaches. Presenters will share lessons for achieving community involvement, revitalization and resilience from area-wide planning approaches used to address brownfields or other community challenges and discuss how states can support such comprehensive collaborative approaches. They will apply these lessons to addressing significant current challenges, such as displacement and gentrification. For more information and to register, see

ITRC TPH Risk Evaluation at Petroleum-Contaminated Sites – June 19, 2019, 1:00PM-3:15PM EST (17:00-19:15 GMT). The basis for this training course is the ITRC guidance: TPH Risk Evaluation at Petroleum-Contaminated Sites (TPHRisk-1, 2018). The guidance builds on long-standing and current research and experience, and presents the current science for evaluating TPH risk at petroleum-contaminated sites. As a participant in this training you should learn to: recognize the ITRC document as a go-to resource for evaluating TPH risk at petroleum-contaminated sites, recognize how TPH -impacted media interacts with the environment and changes over time, select appropriate analytic method(s) to match site objectives, and apply the decision framework to determine when a site-specific target level may be more appropriate than a generic screening level for TPH.

FRTR Presents…Per- and Polyfluoroalkyl Substances (PFAS) Emerging Characterization and Remedial Technologies, Session 1 - June 20, 2019, 1:00PM-2:30PM EDT (17:00-18:30 GMT). This is part of a webinar series featuring presentations delivered at the Fall 2018 FRTR Meeting and related material. The meeting's objective was to identify and discuss the emerging science behind PFAS characterization and remedial technologies. This session will include the following topics: What are PFAS, and What are the Issues with Them?; Treatment Technologies for PFAS Site Management. For more information and to register, see

Superfund Redevelopment Initiative Series: Bona Fide Prospective Purchasers: Liability Protection and Redevelopment - June 28, 2019, 2:00PM-3:30PM EDT (18:00-19:30 GMT). Location, location, location…and liability protection! EPA works with bona fide prospective purchasers to help them understand liability protections and any site use restrictions in order to safely redevelop Superfund sites during and after cleanup. This webinar will provide an overview of liability protections, best practices and specific examples of bona fide prospective purchasers working with EPA to successfully redevelop Superfund sites.

Sustained In Situ Detoxification of Priority Chloroorganic Pollutants, Sponsored by US EPA, Office of Superfund Remediation and Technology Innovation (OSRTI) Archive of Mar 13, 2017 Seminar (1 Hours). Contaminated site cleanup and environmental stewardship are costly tasks and continued research and innovation can lower the financial burden to site owners and to the taxpayer. A variety of technologies addressing groundwater contamination emerged and have been implemented. Bioremediation takes advantage of naturally occurring microorganisms that detoxify contaminants and in situ implementation of this approach promises to meet cleanup goals at reasonable costs. While biostimulation and bioaugmentation have been successfully applied at numerous sites, the current approaches should be considered brute-force, and more refined treatment (i.e., precision bioremediation) will result in a similar reduction of contaminant concentrations at substantially lower capital investment and lesser environmental impacts. Progress in understanding of the microbiology contributing to chlorinated solvent detoxification under anoxic conditions serves as an example how investments in fundamental research and translational efforts can advance bioremediation from an empirical practice to an approach with predictable outcomes.

Incremental Sampling, San Francisco, CA, August 1, 2019. This training course focuses on the theory and application of ITRC's Incremental Sampling Methodology (ISM), composite sampling designs, and hybrids of the two. Incremental Sampling (IS) hybrid designs are useful to address multiple project goals simultaneously. Since "representativeness" is a key aspect of data quality and ISM/IS data are demonstrably more representative than most discrete data, it will be argued that IS data are indeed "better" than non-IS data. The course will answer questions such as: what is the difference between ITRC's ISM and EPA's IS strategies? Is there written EPA guidance? What features should an ISM or IS design have? Can IS give project risk assessors the data they want, while simultaneously meeting the RPM's own data needs for characterization or remedial design? How are background concentrations determined and comparisons to background handled using IS? Do we know whether IS "worked" for the project? For more information and to register, see
