For more information and to register, see http://www.itrcweb.org or http://clu-in.org/live .

ITRC Integrated DNAPL Site Strategy - June 12, 2014, 11:00AM-1:15PM EDT (15:00-17:15 GMT). The ITRC Integrated Dense Nonaqueous Phase Liquid Site Strategy (IDSS-1, 2011) technical and regulatory guidance document will assist site managers in development of an integrated site remedial strategy. This course highlights five important features of an IDSS including: a conceptual site model (CSM) that is based on reliable characterization and an understanding of the subsurface conditions that control contaminant transport, reactivity, and distribution; remedial objectives and performance metrics that are clear, concise, and measureable; treatment technologies applied to optimize performance and take advantage of potential synergistic effects; monitoring based on interim and final cleanup objectives, the selected treatment technology and approach, and remedial performance goals; and reevaluating the strategy repeatedly and even modifying the approach when objectives are not being met or when alternative methods offer similar or better outcomes at lower cost.

Frequently-Asked Questions about Monitored Natural Attenuation in Groundwater - June 13, 2014, 1:30PM-3:00PM EDT (17:30-19:00 GMT). The talk will highlight a recently-published guidance document that uses the Frequently Asked Questions (FAQs) format to provide a concise overview of current knowledge regarding management of subsurface contaminant releases using monitored natural attenuation (MNA). The envisioned audience includes state regulators, federal regulators, industry, consultants, DoD staff, and members of the local community involved in selecting remedies for contaminated sites. The intended value of the document is to provide current knowledge in support of sound decisions. In the interest of brevity, the FAQs assume that the reader has a general understanding of hydrogeology, the movement of chemicals in porous media, remediation technologies, and the remedy selection process. The FAQ for MNA was inspired by the fact that it has been over a decade since publication of Natural Attenuation of Fuels and Chlorinated Solvents which was co-authored by one of the FAQ authors (Newell). While still useful for certain topics, by 2014 it was missing several important advances in characterization, data interpretation, and regulatory thinking that are now mainstays of MNA. The FAQ for MNA is an attempt to identify and highlight the important advances that have occurred since 1999. As part of the webinar, Dr. John Wilson, formally of USEPA and now with Scissortail Environmental, will be interviewed and give his perspective about how MNA fits into today's remediation projects.

ITRC Green & Sustainable Remediation - June 17, 2014, 2:00PM-4:15PM EDT (18:00-20:15 GMT). Many state and federal agencies are just beginning to assess and apply green and sustainable remediation (GSR) into their regulatory programs. This training provides background on GSR concepts, a scalable and flexible framework and metrics, tools and resources to conduct GSR evaluations on remedial projects. The training is based on the ITRC's Technical & Regulatory Guidance Document: Green and Sustainable Remediation: A Practical Framework (GSR-2, 2011) as well as ITRC's Overview Document, Green and Sustainable Remediation: State of the Science and Practice (GSR-1, 2011). Beyond basic GSR principles and definitions, participants will learn the potential benefits of incorporating GSR into their projects; when and how to incorporate GSR within a project's life cycle; and how to perform a GSR evaluation using appropriate tools. In addition, a variety of case studies will demonstrate the application of GSR and the results. The training course provides an important primer for both organizations initiating GSR programs as well as those organizations seeking to incorporate GSR considerations into existing regulatory guidance. For more information and to register, see http://www.itrcweb.org or http://clu-in.org/live .

Military Munitions Support Services - MMRP Tools - June 24, 2014, 1:00PM-4:45PM EDT (17:00-20:45 GMT). This is one of the monthly webinar sessions for the Military Munitions Support Services (M2S2) community. During this session, speakers will make presentations on a variety of topics relative to the latest updates on successful use of MMRP tools such as VSP, UXO Estimator, and advanced classification. For more information and to register, see http://clu-in.org/live .

ITRC Groundwater Statistics for Environmental Project Managers - June 26, 2014, 2:00PM-4:15PM EDT (18:00-20:15 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. For more information and to register, see http://www.itrcweb.org or http://clu-in.org/live .

CEC Preliminary Assessment/Site Inspection (PA/SI) Webinar Series - June 30, July 2, 7, 9, 11, 14, 21, 28, 30. The CERCLA Education Center (CEC) is offering a nine-part Preliminary Assessment and Site Inspection (PA/SI) Webinar Series in June and July 2014. PA/SI is an intermediate training course designed for personnel who are required to compile, draft and review PA, SI and HRS documentation records and packages submitted for sites proposed for the National Priorities List (NPL). This course is open to EPA, federal, state, tribal and contractor personnel who support site investigation programs. The PA/SI Webinar Series provides an introduction to the Superfund site assessment process and describes the preliminary assessment and site inspection phases of this process. The course will incorporate a mix of lecture and exercises using Quickscore for each of the four pathways. The objective of the exercise is to give participants the opportunity to evaluate and score PA information using the HRS Quickscore software. Participants will use information from a fictitious site to (1) evaluate and calculate a preliminary HRS score, and (2) develop release and target hypotheses that should be pursued in an SI. In order to receive credit for taking the course, participants must participate in each session. If you are unable to make one of the sessions, archived versions will be made available at www.clu-in.org that you can take to receive credit for the missed live session. In order to receive credit for a missed session, you must complete the missed session within 2 months of the originally scheduled date and submit an evaluation form from that archived module. For more information and to register, see http://clu-in.org/live .

EPA Issues New Groundwater Guidance Document. The Office of Superfund Remediation and Technology Innovation and the Federal Facility Restoration and Reuse Office recently issued a new groundwater guidance document, the Groundwater Remedy Completion Strategy (OSWER Directive 9200.2-144). Its purpose is to help focus resources on the information and decisions needed to effectively complete groundwater cleanups. It is part of a suite of groundwater guidance, including the 2011 Groundwater Road Map (http://www.epa.gov/superfund/health/conmedia/gwdocs/pdfs/gwroadmapfinal.pdf), being developed by EPA to help focus resources on the information and decisions needed to effectively complete groundwater cleanups (May 2014, 28 pages).

Technology News and Trends (EPA 542-N-14-001). This issue highlights how remedies for contaminated sites may be vulnerable to the impacts of climate change and how measures may be taken to adapt remedies to the impacts. Potential impacts include extreme or sustained changes in temperatures, increased flood events or droughts, increased wind intensity, more frequent and intense wildfires, and sea level rise. The U.S. EPA Superfund program has developed an approach that raises awareness of the vulnerabilities and applies climate change science as a standard business practice in site cleanup projects. Articles featured in this issue examine vulnerabilities at three National Priorities List sites, describe the effects of intense weather events at these sites, and detail adaptation measures already implemented or planned to increase the remedies' resilience to climate change impacts (May 2014).
