FRTR Presents…Heavy Metals-Mining Site Characterization and Treatment Session 1 - July 10, 2017, 1:00PM-3:00PM EDT (17:00-19:00 GMT). This presentation describes the Red Devil Mine's risk assessment process, a "multiple lines of evidence" approach developed by the Bureau of Land Management (BLM) to incorporate a number of site-specific risk assessment findings into site decision making. Mercury and other site contaminants from Red Devil Mine and other abandoned mines in the Kuskokwim River watershed have been measured in multiple media, leading to concerns about human and ecological risk. Of specific concern is whether mercury methylation and food chain biomagnification poses a risk to human subsistence consumers of locally caught fish. We discuss a number of data sets used to evaluate these risks, including multi-year telemetry studies to track fish movements in relation to mercury sources throughout the Kuskokwim watershed. Fish tissue concentrations of mercury were also collected from many of the tagged fish and are discussed in the context of site and regional consumption patterns.

ITRC Groundwater Statistics for Environmental Project Managers - July 18, 2017, 1:00PM-3:15PM EDT (17:00-19:15 GMT). Statistical techniques may be used throughout the process of cleaning up contaminated groundwater. It is challenging for practitioners, who are not experts in statistics, to interpret, and use statistical techniques. ITRC developed the Technical and Regulatory Web-based Guidance on Groundwater Statistics and Monitoring Compliance (GSMC-1, 2013) and this associated training specifically for environmental project managers who review or use statistical calculations for reports, who make recommendations or decisions based on statistics, or who need to demonstrate compliance for groundwater projects. The training class will encourage and support project managers and others who are not statisticians to: use the ITRC Technical and Regulatory Web-based Guidance on Groundwater Statistics and Monitoring Compliance (GSMC-1, 2013) to make better decisions for projects; apply key aspects of the statistical approach to groundwater data; and answer common questions on background, compliance, trend analysis, and monitoring optimization. ITRC's Technical and Regulatory Web-based Guidance on Groundwater Statistics and Monitoring Compliance (GSMC-1, 2013) and this associated training bring clarity to the planning, implementation, and communication of groundwater statistical methods and should lead to greater confidence and transparency in the use of groundwater statistics for site management.

Military Munitions Support Services - Making Decisions - July 20, 2017, 1:00PM-4:15PM EDT (17:00-20:15 GMT). This session will discuss critical elements and concepts of the decision making process. For more information and to register, see

Pre-CERCLA Screening Webinar - July 24, August 15, 30, 2017, 1:00PM-4:00PM EDT (17:00-20:00 GMT). The Office of Superfund Remediation and Technology Innovation (OSRTI) is offering a training webinar on the recent "Pre-CERCLA Screening Guidance" issued by the U.S. EPA in December 2016. This guidance is used by EPA, State, and Tribal Superfund site assessment staff and support contractors when deciding if a new site should be added to the Superfund "active site inventory" for more thorough pre-remedial site evaluation. The training webinar will cover all elements of the guidance, from planning the screening to approving the recommended course of action based on the screening. It includes an in-depth discussion of the Pre-CERCLA Screening Checklist/Decision Form that must be completed for each Pre-CERCLA screening. The webinar provides opportunities for participation by the audience, including a section for questions and answers. Recommended Audience: EPA, State, and Tribal staff and managers and contractor support staff who are involved with planning, conducting, reviewing, and approving Pre-CERCLA screening activities. For more information and to register, see

ITRC Geospatial Analysis for Optimization at Environmental Sites - July 25, 2017, 1:00PM-3:15PM EDT (17:00-19:15 GMT). The purpose of ITRC's Geospatial Analysis for Optimization at Environmental Sites (GRO-1) guidance document and this associated training is to explain, educate, and train state regulators and other practitioners in understanding and using geospatial analyses to evaluate optimization opportunities at environmental sites. With the ITRC GRO-1 web-based guidance document and this associated training class, project managers will be able to: evaluate available data and site needs to determine if geospatial analyses are appropriate for a given site; for a project and specific lifecycle stage, identify optimization questions where geospatial methods can contribution to better decision making; for a project and optimization question(s), select appropriate geospatial method(s) and software using the geospatial analysis work flow, tables and flow charts in the guidance document; with geospatial analyses results (note: some geospatial analyses may be performed by the project manager, but many geospatial analyses will be performed by technical experts), explain what the results mean and appropriately apply in decision making; and use the project manager's tool box, interactive flow charts for choosing geospatial methods and review checklist to use geospatial analyses confidently in decision making.

FRTR Presents…Heavy Metals-Mining Site Characterization and Treatment Session 2 - July 26, 2017, 1:00PM-3:00PM EDT (17:00-19:00 GMT). This webinar will focus on different techniques that can be implemented for site characterization and bioremediation. Aqueous Geochemical Modeling can be used to evaluate the cost effectiveness and feasibility of treatment strategies for metal-laden discharges from coal and metal mines. Best practices for monitoring and modeling Anaerobic biochemical reactors (BCR) will be described as it relates to bioremediation of mining sites. For more information and to register, see

Petroleum Vapor Intrusion: Fundamentals of Screening, Investigation, and Management - ITRC 2-day Classroom Training, Ann Arbor, MI, October 10-11, 2017, includes optional bonus day on October 12 with a Vapor intrusion update from the Michigan Department of Environmental Quality. This 2-day ITRC classroom training is based on the ITRC Technical and Regulatory Guidance Web-Based Document, Petroleum Vapor Intrusion: Fundamentals of Screening, Investigation, and Management (PVI-1, 2014) and led by internationally recognized experts. Within the training class - hear about EPA's Technical Guide For Addressing Petroleum Vapor Intrusion At Leaking Underground Storage Tank Sites (June 2015). The ITRC guidance document and EPA guide are complementary documents with the ITRC training course providing the "how-to" knowledge and skills for screening, investigating, and managing the petroleum vapor intrusion pathway. The class will enable you to develop the skills to screen-out petroleum sites based on the scientifically-supported ITRC strategy and checklist; focus the limited resources investigating those PVI sites that truly represent an unacceptable risk; and communicate ITRC PVI strategy and justify science-based decisions to management, clients, and the public. Interactive learning with classroom exercises and Q&A sessions will reinforce these course learning objectives. For local, state, and federal government; students; community stakeholders; and tribal representatives, ITRC has a limited number of fee waivers available. The ITRC 2-day class is preapproved for continuing education for CT LEPs, MA LSPs, and SC PGs and approval has been requested for DE PGs, NE Water Well Standards, and NJ LSRPs.

Groundwater High-Resolution Site Characterization (HRSC), Dallas, TX, November 15-16, 2017. This training course focuses on groundwater characterization and discusses (1) the impacts of subsurface heterogeneity on the investigation and cleanup of groundwater and related media, (2) the need for scale-appropriate measurements and adequate data density, and (3) the tools and strategies that are available to overcome the impacts of subsurface heterogeneity. After taking this course, participants will be armed with information that will allow them to improve their subsurface investigation approaches and develop more realistic and comprehensive conceptual site models (CSM). CSMs developed based on HRSC strategies and tools will decrease site uncertainty, improve the remedy selection process for groundwater remedies, and better enable the evaluation, design, and implementation of targeted in situ and ex situ groundwater remedies. The Groundwater HRSC course is an advanced 2-day course. The recommended audience includes EPA, federal, state, tribal and private industry technical project managers, practitioners and other stakeholders involved in groundwater investigation and remediation.
