Superfund Redevelopment Initiative Series: Superfund and Cultural Competence - Building a Foundation for Effective Community Engagement - August 2, 2018, 2:00PM-3:30PM EDT (18:00-19:30 GMT). EPA staff interact with impacted communities across the country. These communities may represent a broad range of cultures, including cultures based in race/ethnicity, class, place and other forms of identity. Each EPA site team may also represent a diverse range of cultural perspectives, skill sets and differing professional cultures. This webinar will show how understanding cultural competence skills and tools can help people connect across difference or perceived difference and work together more effectively. This webinar will deepen participants' understanding of what culture is and how it impacts Superfund work, and demonstrate through a series of case studies how becoming culturally competent can improve remedial outcomes, prepare job trainees for successfully entering the workforce, and improve dynamics of remedial teams whose members have different areas of expertise. The Superfund Redevelopment Initiative is hosting this webinar and is happy to answer any follow up questions about the webinar from the press or other interested parties.

NARPM and OSC Academy Presents…NHPA for RPMs and OSCs - August 9, 2018, 1:00PM-3:00PM EDT (17:00-19:00 GMT). This webinar provides OSCs and RPMs with an overview of the National Historic Preservation Act (NHPA) and the requirements of Section 106 under CERCLA. The focus will be on EPA's Emergency Response and Removal Program. NHPA applies to your response action if your action constitutes an undertaking and will have a potential effect on a property that is eligible for or included in the National Register of Historic Places. The overview of the steps of the Section 106 consultation process includes: a review of NHPA under CERCLA; determining if a response action constitutes an undertaking; establishing the area of potential effects of the undertaking; identifying any historic properties within that area, and evaluating whether the undertaking will affect such properties, and if so, whether the effects may be adverse; and where there are adverse effects anticipated, identifying ways to minimize or mitigate any adverse effects. The primary audience for this training is EPA OSCs and RPMs; however, it is open to other federal agencies, states, tribes and consultants who are interested in learning more about the NHPA statute.

NARPM Presents…Using Bioavailability to Assess Contaminated Sediment Risk: Passive Sampling and Porewater Remedial Goals (PWRGs) - August 13, 2018, 1:00PM-3:00PM EDT (17:00-19:00 GMT). This webinar will introduce the use of passive samplers to assess bioavailability and the development of Porewater Remediation Goals (PWRG). Passive sampling devices (PSD) are a technology with growing acceptance for measuring porewater concentrations and assessing bioavailability of contaminants in sediment, particularly for common sediment contaminants such as PCBs, PAHs, chlorinated pesticides and dioxin-like compounds. Instructors will explain the basics of what passive samplers are and how they work, as well as provide an overview of the deployment, analysis, and application of PSDs. The webinar will also discuss the derivation of Porewater Remediation Goals (PWRG) for the protection of the benthic organisms using exposures measured with PSDs. This section of the course will focus on the application of PSD data to ecological risk assessment, including the application of Final Chronic Values from Ambient Water Quality Criteria, use of PSD in toxicity and bioaccumulation testing, development of a site specific PWRG, and calculation of a sediment RG based on site-specific equilibrium partitioning. Instructors will also discuss the implementation of PWRGs as it relates to risk assessment and management at Superfund sediment sites. By taking the webinar, participants will achieve the following objectives: understand how PSD measures bioavailability of contaminants in sediment porewater; be provided with an overview for planning and executing a PSD sampling event; understand how to apply PSD data to ecological risk assessment; learn how to develop a site-specific PWRG to protect the benthic organisms; and consider other uses of PSD methods for RI/FS, remedy selection, and remedy implementation at Superfund sediment sites. The target audience is EPA Remedial Project Managers and risk assessors, as a well as other regulatory staff, contractors, and responsible parties. For more information and to register, see

ITRC Long-term Contaminant Management Using Institutional Controls - August 14, 2018, 1:00PM-3:15PM EDT (17:00-19:15 GMT). Institutional controls (ICs) are administrative or legal restrictions that provide protection from exposure to contaminants on a site. When ICs are jeopardized or fail, direct exposure to human health and the environment can occur. While a variety of guidance and research to date has focused on the implementation of ICs, ITRC's Long-term Contaminant Management Using Institutional Controls (IC-1, 2016) guidance and this associated training class focuses on post-implementation IC management, including monitoring, evaluation, stakeholder communications, enforcement, and termination. The ITRC guidance and training will assist those who are responsible for the management and stewardship of ICs. After attending the training, participants will be able to: describe best practices and evolving trends for IC management at individual sites and across state agency programs; use this guidance to improve IC reliability and prevent IC failures, improve existing, or develop new, IC Management programs, identify the pros and cons about differing IC management approaches; use the tools to establish an LTS plan for specific sites; and use the elements in the tools to understand the information that should populate an IC registry or data management system.

Military Munitions Support Services AGC QA Seeding- August 15, 2018, 1:00PM-4:00PM EDT (17:00-21:00 GMT). Contractor performance metrics are measured by two blind seeding systems on Munitions Response (MR) projects - Quality Assurance and Quality Control. Quality Assurance (QA) seeding is the primary quality system used by the Government to independently check the Contractor's performance at MR sites. QA seeding consists of Government personnel (or a third-party QA Contractor) burying blind seeds at depths and in locations that allow for easy detection. Whereas the Quality Control (QC) seeding is implemented by the Contractor to continually test the depth of detection of their instruments and verify coverage. While QC seeding is generally a larger program with a higher density and variety of blind seeds, it is operated by the Contractor and can present a potential conflict of interest of performance by either not having or not abiding by a firewall plan. Outside of the initial input into the development of the UFP- or AGC-QAPP, the QC seeding program is reported to the Government and taken at face value. The Range Support Center has several challenging projects that overcame significant hurdles to their quality systems, both QA and QC. This M2S2 webinar will present project case studies and introduces a new template for use in scoping a QA seeding program. For more information and to register, see or

ITRC Bioavailability of Contaminants in Soil: Considerations for Human Health Risk Assessment - August 16, 2018, 1:00PM-3:15PM EDT (17:00-19:15 GMT). The basis for this training course is the ITRC guidance: Bioavailability of Contaminants in Soil: Considerations for Human Health Risk Assessment (BCS-1). This guidance describes the general concepts of the bioavailability of contaminants in soil, reviews the state of the science, and discusses how to incorporate bioavailability into the human health risk assessment process. The target audience for this guidance and training course are: project managers interested in decreasing uncertainty in the risk assessment which may lead to reduced remedial action costs, and risk assessors new to bioavailability or those who want additional confidence and training in the current methods and common practices for using bioavailability assessment to more accurately determine human health risk at a contaminated site. As a participant in this training you should learn to: apply the decision process to determine when a site-specific bioavailability assessment may be appropriate, use the ITRC Review Checklist to develop or review a risk assessment that includes soil bioavailability, consider factors that affect arsenic, lead and PAH bioavailability, select appropriate methods to evaluate soil bioavailability, and use tools to develop site-specific soil bioavailability estimates and incorporate them into human health risk assessment.

Vapor Intrusion (VI) Investigation using the Trace Atmospheric Gas Analyzer (TAGA) Mobile Laboratories - August 29, 2018, 1:00PM-2:30PM EDT (17:00-18:30 GMT). Vapor intrusion has been a topic of intense interest in the United States for the recent past. The concern that the vapor intrusion pathway poses is whether an unacceptable risk exists for the occupants. To determine the risk associated with the vapor intrusion pathway, confounding factors due to the presence of these chemical from other sources need to be qualitatively and quantitatively identified so that the contributions from the vapor intrusion alone can be assessed. Because risk is compound specific and many compounds have unacceptable chronic risk levels at extremely low concentrations, an analytical technique is needed that has high selectivity and sensitivity, as well as, continuous real-time analytical updates to accurately and economically assess vapor intrusion sites. This presentation addresses a technology and practice that meets these requirements. This webinar is a result of Recommendation 9 of EPA's Superfund Task Force, which encourages the Superfund program to "utilize state-of-the-art technologies to expedite cleanup." Actions under this recommendation include expanding the use of new remediation technologies and approaches to address contaminated sites. For more information and to register, see

NARPM Presents…Tools for Estimating Groundwater Contaminant Flux to Surface Water - September 5, 2018, 1:00PM-3:00PM EDT (17:00-19:00 GMT). Surface water bodies adjacent to sites with contaminated groundwater may receive impacts that impair otherwise functional ecosystems and create new exposure pathways, increasing human health risks. Optimizing site characterization protocols to improve the remedy design effort is best achieved by developing knowledge of the potential extent and magnitude of contaminated groundwater discharge into the surface water body. Through field-based research, EPAs Office of Research and Development has developed several approaches to more reliably characterize system hydrology and assess contaminant flux. A series of standard methods and spreadsheet-based calculation tools have been developed to facilitate data collection and analysis, and all in an affordable and consistent manner. A case study example will be used to highlight these novel approaches to improve understanding of the spatial and temporal dynamics of contaminant transport across the groundwater-surface water transition zone.
