ITRC Project Risk Management for Site Remediation, April 12, 2011, 2:00PM-4:15PM EDT (18:00-20:15 GMT). Remediation Risk Management (RRM) is a course of action through which all risks related to the remediation processes (site investigations, remedy selection, execution, and completion) are holistically addressed in order to maximize the certainty in the cleanup process to protect human health and the environment. Remediation decisions to achieve such a goal should be made based on threshold criteria on human health and ecological risks, while considering all the other potential project risks. Through this training course and associated ITRC Technical and Regulatory Guidance Document: Project Risk Management for Site Remediation (RRM-1, 2011), the ITRC RRM team presents tools and processes that can help the site remediation practitioner anticipate, plan for, and mitigate many of the most common obstacles to a successful site remediation project. Examples of project risks include remediation technology feasibility risks; remedy selection risks; remedy construction, operation and monitoring risks; remedy performance and operations risks; environmental impacts of systems during their operation; worker safety risk, human health and ecological impacts due to remedy operation; as well as costs and schedules risks including funding and contracting issues.

Community Engagement Activities for Safe Drinking Water, April 14, 2011, 1:00PM-3:00PM EDT (17:00-19:00 GMT). In this seminar sponsored by the Superfund Research Program (SRP), Dr. Laurie Reynolds Rardin, SRP funded researcher from Dartmouth College will present "Face-To-Face Communication Empowers Communities to Spread the Word." This presentation will focus on the Dartmouth Toxic Metals Superfund Research Program Research Translation Core's recently produced "In Small Doses: Arsenic," a 10-minute movie (www.insmalldoses.org) which explains how and why owners of private wells in northern New England should check the levels of arsenic in their drinking water. By providing this information in a visually engaging format, the goal was to persuade private well owners to test their wells and put in an arsenic remediation system if warranted. Face-to-face communication and access to copies of the video proved to be one of the best methods of distribution by expanding the delivery network and allowing the movie to be shown by local town government and public health officials, residents, and on local cable channels. Following her presentation, SRP funded researcher from UC-Davis Radomir Schmidt will discuss a MTBE bioremediation project in Glennville, CA. The project was designed to test existing bioreactor technology for potential drinking water production. The UC-Davis researchers tested for a panel of potential waterborne pathogens. They sought to promote a sense of project ownership in local residents through information exchange meetings, demonstrations of the bioremediation process, and by recruiting locals to help monitor the day-to-day running of the bioreactor.

ITRC Incorporating Bioavailability Considerations into the Evaluation of Contaminated Sediment Sites, April 26, 2011, 2:00PM-4:15PM EDT (18:00-20:15 GMT). ITRC's web-based Technical and Regulatory Guidance, Incorporating Bioavailability Considerations into the Evaluation of Contaminated Sediment Sites (Sed-1, 2011) and associated Internet-based training are intended to assist state regulators and practitioners with understanding and incorporating fundamental concepts of bioavailability in contaminated sediment management practices. This guidance and training describe how bioavailability considerations can be used to evaluate exposure at contaminated sediment sites, the mechanisms affecting contaminant bioavailability, available tools used to assess bioavailability, the proper application of those tools, and how bioavailability information can be incorporated into risk-management decisions. This guidance and training also contain summaries of case studies where bioavailability has been assessed and considered in the contaminated sediment remedial decision making process. This guidance and training provide insight on how bioavailability assessments can be used to understand, mitigate, and manage risk at a contaminated sediment site, often at a reduced overall project cost.

ITRC Enhanced Attenuation of Chlorinated Organics: A Site Management Tool, April 28, 2011, 11:00AM-1:00PM EDT (15:00-17:00 GMT). This training on the ITRC Technical and Regulatory Guidance for Enhanced Attenuation: Chlorinated Organics (EACO-1, 2008) describes the transition (the bridge) between aggressive remedial actions and MNA and vise versa. Enhanced attenuation (EA) is the application of technologies that minimize energy input and are sustainable in order to reduce contaminant loading and/or increase the attenuation capacity of a contaminated plume to progress sites towards established remedial objectives. Contaminant loading and attenuation capacity are fundamental to sound decisions for remediation of groundwater contamination. This training explains how a decision framework which, when followed, allows for a smooth transition between more aggressive remedial technologies to sustainable remedial alternatives and eventually to Monitored Natural Attenuation. This training will demonstrate how this decision framework allows regulators and practitioners to integrate Enhanced Attenuation into the remedial decision process.

Final Report: Technical Assistance for the Kearsarge Metallurgical Corporation Superfund Site, Conway, New Hampshire, EPA Region 1 (EPA 542-R-09-014). This report reviews and provides recommendations for a long-term groundwater monitoring network for the Kearsarge Metallurgical Corporation Superfund site (KMC site). The KMC site is a former foundry and metal fabrication facility in Conway, New Hampshire, listed on the National Priorities List (NPL) in 1984. The site is currently in a long-term operation and maintenance (O&M) phase. The primary goal of developing an optimized groundwater monitoring strategy at the KMC site is to create a dataset that fully supports site management decisions relating to the long-term remedial strategy and reuse options for the property. In this report, the current KMC site groundwater monitoring network has been evaluated using a formal qualitative approach as well as statistical tools found in the Monitoring and Remediation Optimization System (MAROS) software. The evaluation of the monitoring system included data collected both prior to and during active groundwater extraction (1983 - 2005) and after cessation of the extraction remedy (2006 - 2009). Network recommendations are made for groundwater sampling frequency and location based on lines of evidence developed from qualitative factors as well as statistical results (December 2009, 120 pages).
