Arsenic - Interventions - April 15, 2013, 12:00PM-2:00PM EDT (16:00-18:00 GMT). In the first presentation SRP Researcher Joseph Calo, Ph.D., will discuss his team's latest research on developing a spouted vessel/fixed bed filter system for the removal of arsenic from water. The system uses zero-valent iron (ZVI) particles circulating in a spouted vessel that continuously generates active colloidal iron corrosion products. These corrosion products are generated by the "self-polishing" action between ZVI source particles rolling in the moving bed that forms on the conical bottom of the spouted vessel. This action also serves as a "surface renewal" mechanism for the particles and provides for maximum ZVI material utilization. The colloidal material produced in this fashion is continuously captured and concentrated in an internal fixed bed filter where arsenic complexation occurs. This system has been shown to reduce 100 ug/L of arsenic to below detectable levels in less than an hour. Calo's presentation will focus on the spouted vessel/fixed bed filter system for removing arsenic from water, and he will share his most recent research results. In the second presentation SRP Researcher Girish Srinivas, Ph.D., will discuss research being conducted by TDA Research, Inc. (TDA) to develop a cost effective, simple point-of-use (POU) water purifier. The purifier is based on capacitive deionization (CDI) for removing problematic toxic ionic contaminants from well water not attached to a large public water works. TDA's CDI technology can effectively remove perchlorate, nitrate, arsenic, lead, and other harmful inorganic ions from well water to meet EPA drinking water specifications in a simple, DC powered device. The technology can be used for POU applications (e.g. under the sink) in homes that use well water or in developing countries at well sites, where, if power is unavailable, it can be operated using a simple photovoltaic system.

ITRC Project Risk Management for Site Remediation - April 16, 2013, 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.

ITRC Incorporating Bioavailability Considerations into the Evaluation of Contaminated Sediment Sites - April 18, 2013, 11:00AM-1:15PM EDT (15:00-17:15 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. For more information and to register, see http://www.itrcweb.org or http://clu-in.org/live .

ITRC Green & Sustainable Remediation - April 23, 2013, 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.

Participants learn how statutes and regulations are developed. The session provides an overview of U.S. environmental regulations that have been created to control, manage or modify our activities and the effects of these regulations on the health of human beings and the natural environment. Additionally, the session provides a brief history of environmental laws and the origins of EPA. For more information and to register, see http://clu-in.org/live .

ITRC Integrated DNAPL Site Strategy - April 25, 2013, 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.

Optimization Review: Sidney and Richardson Hill Road Landfills, Delaware County, New York (EPA 542-R-11-011). The 72-acre Sidney Landfill site is located on Richardson Hill Road, approximately 2 miles south of the Village of Sidney Center in Delaware County, New York. The Richardson Hill Road Landfill (RHRL) site is located immediately to the south of the Sidney Landfill site. The remedies at both National Priorities List (NPL) sites have been implemented by the responsible parties, Amphenol Corporation and Honeywell, Inc., which are the successors to Bendix Corporation and Allied Signal, Inc. These parties are collectively referred to as the Potentially Responsible Parties (PRP) for this report. The capture zone associated with extraction wells at the northern end of the RHRL site is considered part of the Sidney Landfill remedy. The identification of new seeps downhill to the north from the Sidney Landfill, the presence of an apparent hydraulic connection between the two landfills, as well as the persistence of groundwater and sediment contamination at the RHRL site led the EPA to request a study of optimization opportunities for the remedies at these two sites. This optimization review focuses on the groundwater components of the remedies for the two sites and considers soil and sediment contamination only as it may be related to groundwater contamination (August 2012, 82 pages).

The Management of Brownfields Redevelopment : A Guidance Note (2010). This World Bank guidance note is primarily addressed to local or regional public authorities responsible for the management of brownfields in the transition economies of Central and Eastern Europe. The main impetus for this work is to offer perspectives and solutions to one of the many challenges cities are facing, especially in post-socialist emerging market environments, where urban brownfields are a major hurdle to transforming local economies. Brownfields are understood here as derelict or underused sites with real or perceived contamination problems that create an obstacle to their development potential. As such, these sites represent both a problem and an opportunity. View or download at http://documents.worldbank.org/curated/en/2010/03/12413206/management-brownfields-redevelopment-guidance-note .
