The U.S. EPA Technology Innovation and Field Services Division is still looking for two good people. Our Environmental Response Team (ERT) specializes in field support and technical expertise for EPA responses to oil spills, hazardous emergencies, potentially hazardous scenarios, environmental disasters and long-term remedial activities as well as detection and analytical method development for biological and chemical agents. ERT is active in providing both national and international assistance to remediate and limit damage to air, land and water and to evaluate threats to both human and ecological health. The ERT is prepared to respond to environmental emergencies 24 hours a day, seven days a week, 365 days a year.

Last month we posted information on three positions that were to be announced on USAJobs ( The announcement for the two physical scientists is now closed. The Chemist position remains open through June 4. The ERT is now seeking a health physicist through USAJobs. If interested, apply through USAJOBS. The intent of this announcement is to inform you that specific positions in our organization are being competed. Please do not send information to me. I will not respond. Do not call me for information about these positions. Again this information is provided as a service. Formal announcements of federal jobs occur on the USAJOBS site.

Cumulative Risk Assessment Seminar Series - June 2, 16, 30, July 14. EPA's Office of Research and Development and Regions are sponsoring this series of seminars as a forum for discussing the current state of the art and practice of CRA. These seminars will provide information regarding guidance, resources, and recommendations for real world CRA for regulatory and non-regulatory applications. This seminar series is, in part, preparation for the EPA ORD/Regional Workshop on CRA being hosted by Region 5 in Chicago, IL for July 28-30, 2009. The seminar series is publicly open in support of advancing CRA while the workshop will primarily be internal to EPA to enhance policy and other deliberative discussions.

ITRC Enhanced Attenuation of Chlorinated Organics: A Site Management Tool - June 4, 2009, 11:00AM-1:15PM EDT (15:00-17:15 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.

ITRC Protocol for Use of Five Passive Samplers - June 9, 2009, 2:00PM-4:15PM EDT (18:00-20:15 GMT). This training supports the understanding and use of the ITRC Protocol for Use of Five Passive Samplers to Sample for a Variety of Contaminants in Groundwater (DSP-5, 2007). The five technologies included in this document include diffusion samplers, equilibrated grab samplers, and an accumulation sampler. The training starts with information common to all five samples then focuses on each sampler as instructors describe the sampler and explain how it works; discuss deployment and retrieval of the sampler; highlight advantages and limitations; and present results of data comparison studies. For more information and to register, see or .

ITRC In Situ Bioremediation of Chlorinated Ethene - DNAPL Source Zones - June 11, 2009, 11:00AM-1:15PM EDT (15:00-17:15 GMT). Treatment of dissolved-phase chlorinated ethenes in groundwater using in situ bioremediation (ISB) is an established technology; however, its use for DNAPL source zones is an emerging application. This training course supports the ITRC Technical and Regulatory Guidance document In Situ Bioremediation of Chlorinated Ethene: DNAPL Source Zones (BioDNAPL-3, 2008). This document provides the regulatory community, stakeholders, and practitioners with the general steps practitioners and regulators can use to objectively assess, design, monitor, and optimize ISB treatment of DNAPL source zones.

Computational Toxicology: Dose Response Modeling - June 24, 2009, 1:30PM-3:30PM EDT (17:30-19:30 GMT). The Superfund Basic Research Program (SBRP), in collaboration with the US Environmental Protection Agency's Office of Superfund Remediation and Technology Innovation (OSRTI), presents the Spring/Summer 2009 edition of Risk eLearning: "Computational Toxicology: New Approaches for the 21st Century." This series of online seminars will provide an introduction to the key concepts of computational toxicology along with case studies demonstrating the utility of these approaches (e.g. high throughput screening, computer modeling, informatics) to risk assessment. This seminar, the second of the series, will feature SBRP grantees Dr. Melvin Andersen (The Hamner Institute), Dr. Norbert Kaminski (Michigan State University), and Dr. Rory Conolly (NCCT/ORD/USEPA).

Groundwater Contamination and Treatment Department of Energy Sites. The Department of Energy (DOE) has one of the largest groundwater contamination problems and subsequent cleanup responsibilities in the world, in terms of the sheer volume of affected groundwater, number of plumes, range of hydrogeologic settings, and diversity of contaminant types. Plume maps and assessments have been prepared for DOE sites to summarize the nature and extent of groundwater contamination and to identify approaches being taken to remediate the contaminated groundwater. The purpose of this document is to provide DOE Program/Project Managers, upper management, and other interested parties with a snapshot in time of the status of major groundwater contamination and remedial approaches across the DOE Complex (August 2008, 27 pages).

SUBR:IM Acid Tar Lagoons Web Site (2009). This website has been set up as part of a UK EPSRC funded research project 'Restoration of acid tar and acid tar lagoons', to provide a focus for research and information on acid tar lagoons. There is a very little information on acid tars in the public domain. This site aims to partially redress that balance. Specifically it aims to: a) encourage communication and information exchange between researchers and practitioners involved in the investigation and restoration of acid tar lagoons. b) provide an up to date information resource including a comprehensive bibliography.
