TechDirect's purpose is to identify new technical, policy and guidance resources related to the assessment and remediation of contaminated soil, sediments and ground water. Mention of non-EPA documents or presentations does not constitute a U.S. EPA endorsement of their contents, only an acknowledgment that they exist and may be relevant to the TechDirect audience. EPA's Study of the Potential Impacts of Hydraulic Fracturing on Drinking Water Resources: A Progress Report - January 3 and 4, 2013. On December 18, 2012, the U.S. Environmental Protection Agency (EPA) released a report highlighting the progress it has made on its national study to understand the potential impacts of hydraulic fracturing on drinking water resources. This webinar will provide project-specific updates that include research approach, status, and next steps. EPA will also provide updates on the five technical Roundtables held in November 2012. For more information and to register, see http://clu-in.org/live . ITRC Integrated DNAPL Site Strategy, January 8, 2013, 2:00PM-4:15PM EST (19:00-21:15 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. For more information and to register, see http://www.itrcweb.org or http://clu-in.org/live . ITRC Development of Performance Specifications for Solidification/Stabilization - January 10, 2013, 11:00AM-1:15PM EST (16:00-18:15 GMT). The ITRC technical and regulatory guidance document Development of Performance Specifications for Solidification/Stabilization (S/S-1, 2011) and associated Internet-based training provide an approach to assist practitioners and regulators with measuring and determining acceptable S/S performance. This approach developed by the ITRC Solidification/Stabilization Team provides information for developing, testing, and evaluating appropriate site-specific performance specifications and the considerations for designing appropriate long-term stewardship programs. In addition, the approach provides useful tools for establishing an appropriate degree of treatment and regulatory confidence in the performance data to support decision-making. This training and guidance is intended to be beneficial to anyone involved with CERCLA, RCRA, Brownfields, UST or any other regulatory program where S/S has been selected or implemented as a remedial technology. For more information and to register, see http://www.itrcweb.org or http://clu-in.org/live . ITRC Mining Waste Treatment Technology Selection - January 15, 2013, 2:00PM-4:15PM EST (19:00-21:15 GMT). ITRC's Mining Waste Team developed the ITRC Web-based Mining Waste Technology Selection site to assist project managers in selecting an applicable technology, or suite of technologies, which can be used to remediate mine waste contaminated sites. Decision trees, through a series of questions, guide users to a set of treatment technologies that may be applicable to that particular site situation. Each technology is described, along with a summary of the applicability, advantages, limitations, performance, stakeholder and regulatory considerations, and lessons learned. Each technology overview links to case studies where the technology has been implemented. In this associated Internet-based training, instructors provide background information then take participants through the decision tree using example sites. Project managers, regulators, site owners, and community stakeholders should attend this training class to learn how to use the ITRC Web-based Mining Waste Technology Selection site to identify appropriate technologies, address all impacted media, access case studies, and understand potential regulatory constraints.

ITRC A Decision Framework for Applying Attenuation Processes to Metals and Radionuclides - January 17, 2013, 11:00AM-1:15PM EST (16:00-18:15 GMT). This training and the associated ITRC Technical and Regulatory Guidance document, A Decision Framework for Applying Attenuation Processes to Metals and Radionuclides (APMR-1, 2010), is intended for anyone involved with evaluating, investigating, remediating or managing a site that involves metal and radionuclide contaminants in groundwater. This training and document provides: introduction to key attenuation processes for metals and radionuclides, information on incorporating Monitored Natural Attenuation (MNA) into remedial alternatives for metals/rads, and an overview of the decision framework on MNA for metals and radionuclides in groundwater within the larger evaluation framework of a contaminated site.

Superfund Research Program (SRP) Funding Opportunities Web Seminar - January 30, 2013, 1:30PM-3:00PM EST (18:30-20:00 GMT). The SRP will be holding a web seminar to provide information about current "Superfund Hazardous Substance Research and Training Program (P42)" funding opportunities. Primary focus will be on the new multi-project center grant announcement (P42), including an emphasis on changes compared to previous solicitations. Participants will have an opportunity to ask questions. For more information and to register, see http://clu-in.org/live . Technology News and Trends (EPA 542-N-12-006). This issue highlights the use of in situ bioremediation to address groundwater contamination caused by past releases of organic contaminants. Implementation of bioremediation at these sites involves biostimulation techniques, in which amendments are administered to the subsurface to provide nutrition for microorganisms capable of consuming and consequently biodegrading the contaminants, as well as bioaugmentation techniques involving subsurface injection of biodegrading microorganisms that may not already exist onsite (December 2012).

This document provides project background and information about the optimization review conducted at the Fairfield Coal Gasification Plant Superfund Site, including information about site-specific background; the conceptual site model; optimization findings related to source structures and impacted soil removal, the dissolved phase groundwater plume, and establishment of technical impracticability waivers; and optimization recommendations related to improving effectiveness, reducing cost, technical improvement, and site closure (August 2012).
