CEC Hazard Ranking System (HRS) Webinar Series - March 10, 18, 20, 25, 27, April 1, 3, 8, 10. The CERCLA Education Center (CEC) is offering another Hazard Ranking System Webinar Series in March and April 2014 and has expanded the course from six to nine modules. The HRS webinar series is an intermediate-level course designed for personnel who are required to compile, draft and review preliminary assessments (PA), site inspections (SI), and HRS documentation records/packages submitted for proposal to the National Priorities List (NPL). The course is intended for EPA Regional, state, tribal and contractor personnel, who support EPA in the Superfund site assessment/NPL listing process. This course assumes a basic understanding of the HRS and its context within the site assessment process. The training course is intended to enable staff to prepare HRS packages for the NPL and to plan PAs and SIs to address future HRS scoring issues. This training course provides details of the structure and application of the revised HRS and information related to the preparation of HRS packages, including HRS scoresheets, documentation records and site summaries. The course will incorporate an interactive case study for each of the four pathways to provide practical application of the HRS. The webinar series consists of nine two- to three-hour sessions during March and April 2014. In order to receive credit for taking the course, participants must participate in each session. If you are unable to make one of the sessions, archived versions will be made available at that you can take to receive credit for the missed live session. In order to receive credit for a missed session, you must complete the missed session within 2 months of the originally scheduled date and submit an evaluation form from that archived module.

ITRC LNAPL Training Parts 1, 2, and 3 - March 4, 6, 11. Light non-aqueous phase liquids (LNAPLs) are organic liquids such as gasoline, diesel, and other petroleum hydrocarbon products that are immiscible with water and less dense than water. LNAPLs are important because they are present in the subsurface at thousands of remediation sites across the country, and are frequently the focus of assessment and remediation efforts. Part 1 of this training course explains how LNAPLs behave in the subsurface and examines what controls their behavior. Part 1 also explains what LNAPL data can tell you about the LNAPL and site conditions. Relevant and practical examples are used to illustrate key concepts. Part 2 addresses LNAPL characterization and site conceptual model development as well as LNAPL recovery evaluation and remedial considerations. Specifically, Part 2 discusses key LNAPL and site data, when and why those data may be important, and how to get those data. Part 2 also discusses how to evaluate LNAPL recoverability. Part 3 uses the LNAPL conceptual site model (LCSM) approach to identify the LNAPL concerns or risks and set proper LNAPL remedial objectives and technology-specific remediation goals and performance metrics. Part 3 also provides an overview of the LNAPL remedial technology selection framework. For more information and to register, see or .

Introduction to In Situ Bioremediation of Groundwater (EPA 542-R-13-018). In situ bioremediation (ISB) of groundwater involves the encouragement of indigenous bacterial populations to metabolize target contaminants through the addition of various amendments (biostimulation) to the subsurface environment. In addition to amendments, select strains of bacteria may be added to the subsurface to help treat some sites (bioaugmentation). Bacteria perform coupled oxidation/reduction (redox) reactions to live, and bioremediation exploits these reactions to remove contaminants from contaminated media (soil, air, or groundwater). Bacteria can use different electron acceptors (oxidized compounds) and donors (reduced compounds) in the three major oxidation pathways - aerobic respiration, anaerobic respiration, and fermentation. ISB can use all of these pathways, and contaminant degradation may occur through direct metabolism, cometabolism, or abiotic transformations that may result from biological activities. This report is intended for U.S. EPA and state agency site managers and may serve as a reference to designers and practitioners (December 2013, 86 pages). View or download at .

Reference Report on the management of contaminated sites in Europe (2014). The JRC has published a Reference Report led by the IES, which presents the current state of knowledge on the management of contaminated sites in Europe. The report outlines findings such as the following: " There are an estimated 2.5 million potentially contaminated sites in Europe, where soil contamination is suspected and detailed investigations are needed. " Of the circa 115 000 contaminated sites that have already been identified in Europe, nearly half of them (46%) have already been remediated. " Contaminated sites are mainly managed using traditional techniques such as excavation and off-site disposal, which together account for about one third of management practices. " Mining activities, metal industries and gasoline stations are the most frequently reported sources of soil and groundwater contamination. However, the range of polluting activities varies considerably from country to country. " The most frequently occurring contaminants are mineral oils and heavy metals. " Annual national expenditure for the management of contaminated sites is on average about �10 per capita. View or download at,ies_highlights_details.html
