ITRC Groundwater Statistics for Environmental Project Managers - March 5, 2020, 1:00PM-3:15PM EST (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.

ProUCL Utilization 2020: Part 3: Background Level Calculations - March 9, 2020, 1:00PM-2:30PM EDT (17:00-18:30 GMT). ProUCL version 5.1.002 (5.1) is the latest update of the ProUCL statistical software package for analysis of environmental data sets with and without nondetect (ND) observations. In the first installment of a three part ProUCL e-learning seminar series, instructors presented the live interactive use of ProUCL v5.1 from initial data loading, all the way through the major steps of statistical data analysis in ProUCL. The second installment presented live interactive use of ProUCL v5.1 focusing specifically on the finer points of regression and trend analysis within the ProUCL software. The final installment will focus mainly on background dataset analysis and associated background threshold value (BTV) comparisons within the ProUCL software.

Reducing Cost Risk in Remedial Action Budgets Using Supplemental Analyses - March 11, 2020, 1:30PM-3:00PM EDT (17:30-19:00 GMT). The cost estimates for selected remedies in Records of Decision (RODs) that are used for remedial action budgeting often use simplified information (such as scope of work activities and related quantities) as opposed to remedial action (RA) construction cost estimates developed during remedial design. Remedial action budgets developed from the ROD selected remedy cost estimates have inherent limitations due to the use of the estimate (i.e. selecting a remedy through comparisons of alternatives). Due to differing stakeholder perspectives and potential overreliance on the selected remedy cost estimates developed during the ROD, there can be confusion about why the RA cost estimate prepared during Remedial Design is different than the cost estimate in the ROD. Differences between the selected remedy cost estimate in the ROD and the RA cost estimate can lead to difficulties with project execution including the need to request additional funding and/or schedule delays. Based on prior CERCLA project experiences, CDM Smith has developed tools consistent with cost estimating industry standards and EPA guidance that can be used to communicate the reasons for these differences in estimates including Basis of Estimate documents and ROD cost comparison tables. The additional information will focus on case studies and lessons learned from CERCLA projects that led to the development of these tools and explain how they help show the actual differences in remedy scope and related costs as the level of project definition increases during remedial design, for example why cost items that at first glance appear to be similar ("apples to apples") could actually differ ("apples and oranges").

ITRC Long-term Contaminant Management Using Institutional Controls - March 17, 2020, 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.

ITRC Geospatial Analysis for Optimization at Environmental Sites - March 19, 2020, 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 life-cycle stage, identify optimization questions where geospatial methods can contribute 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.

Superfund and Brownfields Funding Vehicles for Tribes - March 23, 2020, 1:00PM-2:30PM EDT (17:00-18:30 GMT). The webinar will provide information about potential tribal funding vehicles to help address contaminated land as well as to build capacity within tribes for environmental response including: Brownfields Funding Opportunities, Superfund Subpart O Funding Opportunities, and Superfund Community Involvement Funding Opportunities. Among the topics covered will be what makes tribes eligible for each of the kinds of funding vehicles, what kinds of activities can be fund by each, and how Superfund and Brownfields funding interact (or don't). The webinar should provide tribal environmental professionals with a greater understanding of different potential funding vehicles that may support their work at impacted sites and should assist them in discussing funding options with their EPA regional counterparts.

ITRC Optimizing Injection Strategies and In Situ Remediation Performance. There are many types of in situ remediation amendments and emplacement technologies, and each site provides unique challenges that can limit the effectiveness of the in situ remedy. The importance of proactive planning, including using processes such as site characterization analysis, bench- and field-testing and/or design optimization testing, and performance evaluation, cannot be overemphasized. Many challenges encountered during in situ remediation can be overcome with a thorough understanding of the contaminant phase and distribution, site hydrogeology and biogeochemistry, and the amendment's physical and chemical characteristics. This comprehensive guidance is intended to assist a broad audience with overcoming common in situ remediation challenges, covering major topics such as remedial design, implementation, and monitoring.
