ITRC Integrated DNAPL Site Characterization - March 2, 2017, 1:00PM-3:15PM EST (18:00-20:15 GMT). The Integrated DNAPL Site Characterization Team has synthesized the knowledge about dense nonaqueous phase liquid (DNAPL) site characterization and remediation acquired over the past several decades, and has integrated that information into a new document, Integrated DNAPL Site Characterization and Tools Selection (ISC-1, 2015). This guidance is a resource to inform regulators, responsible parties, other problem holders, consultants, community stakeholders, and other interested parties of the critical concepts related to characterization approaches and tools for collecting subsurface data at DNAPL sites. After this associated training, participants will be able to use the guidance to develop and support an integrated approach to DNAPL site characterization, including: identify what site conditions must be considered when developing an informative DNAPL conceptual site model (CSM); define an objectives-based DNAPL characterization strategy; understand what tools and resources are available to improve the identification, collection, and evaluation of appropriate site characterization data; and navigate the DNAPL characterization tools table and select appropriate technologies to fill site-specific data gaps.

ITRC Geophysical Classification for Munitions Response - March 9, 2017, 1:00PM-3:15PM EST (18:00-20:15 GMT). This training class and supporting guidance document explain the process of geophysical classification, describe its benefits and limitations, and discuss the information and data needed by regulators to monitor and evaluate the use of the technology. This document and training also emphasize using a systematic planning process to develop data acquisition and decision strategies at the outset of a munitions response effort, as well as quality considerations throughout the project. Stakeholder issues that are unique to munitions response are also discussed. After this training class, participants will: understand the technology and terminology, be ready to engage in the planning process to address quality considerations throughout a project, find tools to transfer knowledge within organizations and to stakeholders, and start to transition mindset to decisions that leave non-hazardous items in the ground. An audience who understand current munitions response tools and procedures (for example, geophysical surveys, sensors, data analysis) will benefit most from this document and training.

Sustained In Situ Detoxification of Priority Chloroorganic Pollutants - March 13, 2017, 1:00PM-2:00PM EDT (17:00-18:00 GMT). 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.

ITRC Integrated DNAPL Site Strategy - March 16, 2017, 1:00PM-3:15PM EDT (17:00-19:15 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 measurable; 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.

Long-Term Contaminant Management Using Institutional Controls. This Interstate Technology & Regulatory Council (ITRC) guide focuses on long-term contaminant management using institutional controls (ICs) to provide protection from exposure to contaminants on a site. This guide assists those who are responsible for ICs stewardship by describing critical elements and best practices for an IC management program based on the successes and lessons learned from established state and federal agency programs. To support cost-effective program development, ITRC developed a downloadable tool that can be used to document critical information about an IC. The tool can help to create a lasting record of the site that includes the regulatory authority, details of the IC, the responsibilities of all parties, a schedule for monitoring IC performance, and other relevant information. The tool generates an editable long-term stewardship plan in Microsoft Word (December 2016). View and use at Download the stewardship tool at

Geospatial Analysis for Optimization at Environmental Sites. Geospatial analysis supports optimization activities throughout all stages of an environmental investigation or cleanup by improving performance of characterization and remediation activities, increasing monitoring efficiency, and justifying decisions. This Interstate Technology & Regulatory Council (ITRC) guide illustrates the practical application of geospatial analyses to support optimization activities and help practitioners apply geospatial analyses to their projects. This information will help state regulators and other practitioners to understand, evaluate, and make informed decisions about geospatial analyses for optimizing activities during environmental investigation or remediation. The material presented provides not only highly technical detail but also introductory information for those who may not have expertise in this area (October 2016). View and use at

Superfund Research Program Research Brief 266: Using Surfactants to Enhance Bioremediation of PAHs in Soil. A second-stage treatment using low levels of surfactants, which are commonly used as dispersing agents, may be a promising method to maximize removal of polycyclic aromatic hydrocarbons (PAHs) at hazardous waste sites, according to findings from the University of North Carolina at Chapel Hill Superfund Research Program (SRP) Center. Researchers identified specific surfactants that enhanced the removal of PAHs from previously treated soil by making the chemicals more accessible for degradation by bacteria. Even though this second-stage treatment removed PAHs, it also increased soil toxicity in many cases, emphasizing the need to better understand toxic by-products of PAH remediation.
