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 www.ciu-in.om 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. For more information and to register, see

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

selection framework. For more information and to register, see http://www.itrcweb.ora or http://ciu-in.ora/iive .

ITRC Biofuels: Release Prevention, Environmental Behavior, and Remediation - March 20,
2014,11:00AM-1:15PM EDT (15:00-17:15 GMT). This training, which is based on the ITRC's
Biofuels: Release Prevention, Environmental Behavior, and Remediation (Biofuels-1, 2011),
focuses on the differences between biofuels and conventional fuels specific to release scenarios,
environmental impacts, characterization, and remediation. The trainers will define the scope of the
potential environmental challenges by introducing biofuel fundamentals, regulatory status, and
future usage projections. Participants will learn how and when to use the ITRC biofuels guidance
document for their projects. They will understand the differences in biofuel and petroleum
behavior; become familiar with the biofuel supply chain, potential release scenarios and release
prevention; be able to develop an appropriate conceptual model for the investigation and
remediation of biofuels; and select appropriate investigation and remediation strategies. For more
information and to register, see http://www.itrcweb.ora or http://ciu-in.ora/iive .

Sustainable Remediation - April 15, 2014,10:00AM-11:00AM EDT (14:00-15:00 GMT). A

pre-conference workshop for the Sustainable Remediation Conference 2014. The webinar aims to
stimulate international exchange by providing a venue for professionals and interested parties from
multiple backgrounds to share experiences and perspectives on how contaminated sites can be
remediated with a lower environmental footprint, and how their reuse can contribute to a more
sustainable land development. The event builds on the Green Remediation Conference
(Copenhagen, November 2009), the 2nd International Conference on Sustainable Remediation
(Vienna, November 2012) and discussions alongside at ConSoil 2010 & 2013 as well as through
virtual events hosted by U.S. EPA. For more information and to register, see http://ciu-in.ora/iive .

ASTM Greener Cleanup Standard Guide: An Introduction - April 25, 2014,1:00PM-3:00PM
EDT (17:00-19:00 GMT). ASTM International, Inc. released its Greener Cleanup Standard Guide
E2893-13, (the "Guide") in November 2013. The Guide offers remediation professionals a clear,
step-wise approach to implementing green remediation projects, and is the most direct guidance of
its kind. This webinar is provided through a collaboration of the Guide's Development Team and
U.S. EPA. The Guide sets forth a 5-step decision-making process to reduce the environmental
footprint of contaminated site assessment and cleanup projects. Through this webinar, participants
will gain insight on the genesis of this ASTM effort, potential applications of the Guide, the
mechanics of actually using it at a project, and how stakeholders are considering its use. This
two-hour Webinar includes a 30-minute closing Q&A session and will be instructed by John Simon,
lead of the Development Team, as well as Carlos Pachon and Deb Goldblum of U.S. EPA. For

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

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 ~lO per capita. View or download at

Groundwater High-Resolution Site Characterization (HRSC), Atlanta, GA, April 3-4, 2014.

This is a two-day training course that focuses on groundwater characterization and discusses (1)
the impacts of subsurface heterogeneity on the investigation and cleanup of groundwater and
related media, (2) the need for scale-appropriate measurements and adequate data density, and
(3) the tools and strategies that are available to overcome the impacts of subsurface heterogeneity.
After taking this course, participants will be armed with information that will allow them to improve
their subsurface investigation approaches and develop more realistic and comprehensive
conceptual site models (CSM). CSMs developed based on HRSC strategies and tools will
decrease site uncertainty, improve the remedy selection process for groundwater remedies, and
better enable the evaluation, design, and implementation of targeted in situ and ex situ
groundwater remedies. The recommended audience for this course includes EPA, federal, state,
tribal, and private industry technical project managers, practitioners and other stakeholders
involved in groundwater investigation and remediation. For more information and to register, see
