includes aqueous wastes generated by ore extraction and processing, as well as mine
drainage and tailings runoff. MIW handling, storage, and disposal is a major
environmental problem in mining districts throughout the U.S and around the world.
Biochemical reactors (BCRs) are engineered treatment systems that use an organic
substrate to drive microbial and chemical reactions to reduce concentrations of metals,
acidity, and sulfate in MIWs. The ITRC Biochemical Reactors for Mining-Influenced
Water technology guidance (BCR-1, 2013) and this associated Internet-based training
provide an in-depth examination of BCRs; a decision framework to assess the
applicability of BCRs; details on testing, designing, constructing and monitoring BCRs;
and real world BCR case studies with diverse site conditions and chemical mixtures. At
the end of this training, you should be able to complete the following activities: describe
a BCR and how it works; identify when a BCR is applicable to a site; use the ITRC
guidance for decision making by applying the decision framework; improve site decision
making through understanding of BCR advantages, limitations, reasonable
expectations, regulatory and other challenges; and navigate the ITRC Biochemical
Reactors for Mining-Influenced Water technology guidance (BCR-1, 2013). For more

Using GIS Tools to Analyze, Compute, and Predict Pollution, Session I -
Exposure Assessment in the Field and links to Human Health - February 6, 2014,
2:00PM-4:00PM EST (19:00-21:00 GMT).Preterm birth, the leading cause of neonatal
mortality in the U.S., may be associated with exposure to legacy and emergent
contaminants in the environment. Puerto Rico has one of the highest rates of preterm
birth, as well as density of Superfund Sites in the United States. As part of NIEHS's
Superfund Research Program, the Puerto Rico Testsite for Exploring Contamination
Threats (PROTECT) is exploring the relationships between exposure to hazardous
chemicals and preterm birth in northern Puerto Rico. Particular attention is given to
chlorinated volatile organic compounds and phthalates, although biomarkers of
phenols, metals, and parabens exposure are also being explored as precursors of
preterm birth. Identification of associations between contaminants and preterm birth
requires collection and integration of complex multi-disciplinary datasets. The first
presentation will describe the data management system being developed by PROTECT
to integrate, manage, analyze, and relate environmental, demographic, exposure
biomarkers, and birth outcome data. The discussion will center on the applicability of
the system, built on a foundation of Earthsoft's EQUIS(R), to assess the extent of
groundwater and tap water contamination, identify other modes of exposure, define
patterns in biomarkers of exposure and birth outcomes from an ongoing birth cohort,
perform relational queries, and map spatial patterns that can be directly visualized with
ArcGIS. Toxic metals are widespread environmental contaminants that are known
human carcinogens and/or developmental toxicants. The levels of metals in private well
water are federally unregulated. The second presenter will describe two studies that
used GIS mapping in North Carolina to examine 1) the spatial patterns of arsenic levels
private wells, and 2) the association between private well levels of arsenic, cadmium,
manganese, and lead and birth defects prevalence. The studies used a statewide
database of private well contaminants collected by the North Carolina Department of
Health and Human Services Division of Public Health as well as data from the North
Carolina Birth Defects Monitoring Program. For more information and to register, see

how to determine ISM Decision Units (DU), the answers to common questions about
ISM sampling design and data analysis, methods to collect and analyze ISM soil
samples, the impact of laboratory processing on soil samples, and how to evaluate ISM
data and make decisions. In addition this ISM training and guidance provides insight on
when and how to apply ISM at a contaminated site, and will aid in developing or
reviewing project documents incorporating ISM (e.g., work plans, sampling plans,
reports). For more information and to register, see http://www.itrcweb.ora or http://ciu-in.ora/iive .

Area-Wide Planning, Superfund Sites, Environmental Justice and Green
Infrastructure: Tying it All Together in the Freeport Community Planning Project -
February 13, 2014, 2:30PM-4:30PM EST (19:30-21:30 GMT). The economic vitality
and the quality of neighborhood housing of the East Side neighborhood of Freeport,
Illinois, have been severely impacted overtime by the neighborhood's location in the
Pecatonica River floodway. In addition, this environmental justice community has
suffered from the legacy of racial segregation, strained relationships with civic
leadership and diminished access to community amenities. EPA's Superfund
Redevelopment Initiative (SRI) selected the East Side neighborhood to receive support
after an initial meeting regarding the CMC Heartland Superfund site in which City staff
identified flood impacts and strained relationships as key challenges to community
revitalization. Designed with the goal of mending and rebuilding the relationship
between the City of Freeport and East Side residents, the resulting community
engagement and planning project has become a shining example of a
community-specific SRI area-wide planning project. This webinarwill provide an
in-depth look at the project and include topics such as restoring strained relationships
between environmental justice communities and government agencies, reusing
contaminated areas to improve neighborhood quality of life, and developing green and
grey infrastructure strategies to reduce flood impacts on residential areas. For more
information and to register, see http://ciu-in.ora/iive .

ITRC Green & Sustainable Remediation - February 20, 2014, 11:00AM-1:15PM
EST (16:00-18:15 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. For more information and to register, see http://www.itrcweb.ora or http://ciu-in.ora/iive .

Why Are So Many Groundwater Contaminant Plumes Persistent? Insights from
Modeling and Characterization - February 24, 2014,1:00PM-3:00PM EST
(18:00-20:00 GMT). This two-part seminar will feature Dr. Graham Fogg of the
University of California Davis Superfund Research Program (SRP) and Dr. Mark
Brusseau from the University of Arizona SRP and will focus on groundwater
remediation issues. Contamination of groundwater by chemicals used in industrial,
commercial, and other applications continues to pose significant threats to human
health and the environment. Due to the complex characteristics of the subsurface and
contaminants, site remediation is often an elusive goal. Dr. Graham Fogg will cover
research on groundwater transport models that aim to improve our understanding of
subsurface conditions and make elusive groundwater remediation more effective.

Recent research shows how reliance on conceptual site models can lead to
mischaracterization of not only the plume, but also remediation success and natural
attenuation. Development of improved tools and methods will be discussed. Dr. Mark
Brusseau will discuss his research on the primary transport characteristics of persistent
groundwater contaminant plumes, with illustration via case study. Methods for
characterizing persistent mass discharge will also be discussed. For more information

Military Munitions Support Services - Munitions Classification - February 25,
2014,1:00PM-4:45PM EST (18:00-21:45 GMT). This is one of the monthly webinar
sessions for the Military Munitions Support Services (M2S2) community. During this
session, speakers will make presentations on a variety of topics relative to advanced
geophysics classification for munitions response projects. For more information and to

register, see http://clu-in.ora/live .

ITRC Groundwater Statistics for Environmental Project Managers - February 27,
2014,11:00AM-1:15PM EST (16:00-18:15 GMT). Statistical techniques may be used
throughout the process of cleaning up contaminated groundwater. It is challenging for
practitioners, who are not experts in statistics, to interpret, and use statistical
techniques. ITRC developed the Technical and Regulatory Web-based Guidance on
Groundwater Statistics and Monitoring Compliance (GSMC-1, 2013) and this
associated training specifically for environmental project managers who review or use
statistical calculations for reports, who make recommendations or decisions based on
statistics, or who need to demonstrate compliance for groundwater projects. The
training class will encourage and support project managers and others who are not
statisticians to: use the ITRC Technical and Regulatory Web-based Guidance on
Groundwater Statistics and Monitoring Compliance (GSMC-1, 2013) to make better
decisions for projects; apply key aspects of the statistical approach to groundwater
data; and answer common questions on background, compliance, trend analysis, and
monitoring optimization. ITRC's Technical and Regulatory Web-based Guidance on
Groundwater Statistics and Monitoring Compliance (GSMC-1, 2013) and this
associated training bring clarity to the planning, implementation, and communication of
groundwater statistical methods and should lead to greater confidence and
transparency in the use of groundwater statistics for site management. For more
information and to register, see http://www.itrcweb.ora or http://ciu-in.ora/iive .

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 http://www.itrcweb.ora or http://ciu-in.ora/iive .

ASTM Standard Guide for Greener Cleanups (E2893-13). EPA representatives
worked with ASTM International, a standard developing organization, to develop a
standard guide intended to encourage property owners, regulatory agencies,
responsible parties, developers, and communities to voluntarily use greener practices
for contaminated site cleanup. In November 2013, ASTM released the resulting
consensus-based "Standard Guide for Greener Cleanups." The guide describes a
process for identifying, evaluating, and incorporating best management practices and,
when appropriate, integrating a quantitative evaluation of the environmental footprint of
cleanup activities. A December memorandum from EPA's Office of Solid Waste and
Emergency Response (OSWER) Assistant Administrator to regional administrators and
OSWER office directors recognizes the standard as a tool that, when implemented
appropriately, can reduce the environmental footprint of cleanup activities while still
meeting site-specific regulatory requirements and objectives. For more information
about and to purchase the Standard, visit httn://www.astm.om/Standards/E2893.htm. To view or

Optimization Review: State Road 114 Ground Water Plume Superfund Site
(Ground Water Treatment System and Soil Vapor Extraction System), Levelland,
Hockley County, Texas (EPA 540-R-013-018).This report provides information about
the optimization review conducted at the State Road 114 Ground Water Plume
Superfund Site in the City of Levelland in Hockley County, Texas. An optimization
review considers the goals of the remedy, available site data, conceptual site model
(CSM), remedy performance, protectiveness, cost-effectiveness and closure strategy. A
strong interest in sustainability has also developed in the private sector and within
federal, state, and municipal governments. Consistent with this interest, optimization
now routinely considers green remediation and environmental footprint reduction during
optimization reviews. This groundwater plume site contains the primary contaminants
1,2-dichloroethane and benzene. The source of the groundwater contamination is a
former petroleum products refinery that operated between 1939 and 1954. The
groundwater remedy consists of a groundwater treatment system and a soil vapor
extraction system (December 2013, 69 pages). View or download at
