Porewater Concentrations and Bioavailability: How You Can Measure Them and
Why They Influence Contaminated Sediment Remediation - Sessions III and IV -
December 1 and 15, 2014. NARPM Presents and Risk e-Learning are offering a
four-part webinar series to help you understand why, how, and when to measure
porewater concentrations and bioavailability as part of contaminated sediment
assessment and management. Hosted jointly by the EPA Contaminated Sediments
Forum and the National Institute of Environmental Health Science's Superfund
Research Program, this webinar series will also focus on the use of passive sampling
devices (PSD) and what they tell us about contaminant bioavailability. Previously held
as a course at the National Association for Remedial Project Managers (NARPM)
Training Program meeting, the webinar series features experts in the field of porewater
and bioavailability and includes lectures and case studies, including practical tips to
maximize the utility of porewater and bioavailability measurements. Presenters will
explain the basics of chemical fate, transport, and uptake, with a focus on porewater as
a key route of exposure and a strong indicator of bioavailability. PSDs are a promising

technology for measuring porewater concentrations and assessing bioavailability,
particularly for common sediment contaminants such as polychlorinated biphenyls
(PCBs), polycyclic aromatic hydrocarbons (PAHs), chlorinated pesticides, and
dioxin-like compounds. The webinar series will include information about direct
measurements of porewater, such as centrifuging sediment samples or Henry
Samplers, which may also be used and are particularly useful for measuring metals.

ITRC Integrated DNAPL Site Strategy - December 2, 2014, 2:00PM-4:15PM EST
(19:00-21:15 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 measurable; 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. For more information and to register, see http://www.itrcweb.ora or http://ciu-in.ora/iive.
ITRC Mining Waste Treatment Technology Selection - December 4, 2014,
11:00AM-1:15PM EST (16:00-18:15 GMT). ITRC's Mining Waste Team developed the
ITRC Web-based Mining Waste Technology Selection site to assist project managers in
selecting an applicable technology, or suite of technologies, which can be used to
remediate mine waste contaminated sites. Decision trees, through a series of
questions, guide users to a set of treatment technologies that may be applicable to that
particular site situation. Each technology is described, along with a summary of the
applicability, advantages, limitations, performance, stakeholder and regulatory
considerations, and lessons learned. Each technology overview links to case studies
where the technology has been implemented. In this associated Internet-based training,
instructors provide background information then take participants through the decision
tree using example sites. Project managers, regulators, site owners, and community
stakeholders should attend this training class to learn how to use the ITRC Web-based
Mining Waste Technology Selection site to identify appropriate technologies, address all
impacted media, access case studies, and understand potential regulatory constraints.

ITRC Biochemical Reactors for Treating Mining Influenced Water - December 9,
2014, 2:00PM-4:15PM EST (19:00-21:15 GMT). Mining influenced water (MIW)
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

Military Munitions Support Services - Munitions Constituents - December 10,
2014,1:00PM-4:30PM EST (18:00-21:30 GMT). This will be a Military Munitions
Support Services seminar with subject matter experts discussing the latest
developments in munitions constituents. For more information and to register, see
http://clu-in.org/live.
ITRC Remedy Selection for Contaminated Sediments - December 11, 2014,
11:00AM-1:15PM EST (16:00-18:15 GMT). ITRC developed the technical and
regulatory guidance, Remedy Selection for Contaminated Sediments (CS-2, 2014), to
assist decision-makers in identifying which contaminated sediment management
technology is most favorable based on an evaluation of site specific physical, sediment,
contaminant, and land and waterway use characteristics. The document provides a
remedial selection framework to help identify favorable technologies, and identifies
additional factors (feasibility, cost, stakeholder concerns, and others) that need to be
considered as part of the remedy selection process. This ITRC training course
supports participants with applying the technical and regulatory guidance as a tool to
overcome the remedial challenges posed by contaminated sediment sites. Participants
learn how to: identify site-specific characteristics and data needed for site decision
making, evaluate potential technologies based on site information, and select the most
favorable contaminant management technology for their site. For more information and
tO register, see http://www.itrcweb.ora Or http://clu-in.ora/live.
ITRC Groundwater Statistics for Environmental Project Managers - December 16,
2014, 2:00PM-4:15PM EST (19:00-21:15 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

Water Treatment: Iron Mountain Mine and Bunker Hill Mining and Metallurgical
Complex Superfund Sites - December 17, 2014,1:00PM-3:00PM EST (18:00-20:00
GMT).This webinar features three presentations on mining-influenced water (MIW)
treatment delivered at the 2014 National Conference on Mining Influenced Waters. The
session focuses on approaches to MIW treatment, operations and maintenance (O&M)
challenges, and characterization and remediation of MIW treatment issues at two
Superfund sites. For more information and to register, see http://ciu-in.ora/iive.

Technology News and Trends (EPA 542-N-14-003). This issue highlights
characterization and remediation strategies for contaminated sediment, which impairs
the uses of many water bodies and is often a contributing factor to the thousands of fish
consumption advisories that have been issued nationwide. As of December 2012,
remedies for 70 large sediment sites were selected under the Superfund program and
Superfund evaluation was underway for another 50 sites. Difficulties in contaminated
sediment cleanup are often associated with the variability of contaminant occurrence or
transport due to changing surface and near-surface water conditions, the adequacy of
characterization tools or techniques, or limitations of remediation technologies
employed in subaqueous settings. Site-specific projects described in this issue
demonstrate development, testing or full-scale use of innovative technologies and
approaches for addressing these issues (Fall 2014). View at httn://ciu-in.om/tnandt/ni4.

New Fact Sheets on Geophysical Classification for Munitions Response (GCMR).
These three fact sheets provide basic information about geophysical classification for
munitions response from different perspectives. The Introductory Fact Sheet, published
in October 2012, provides a discussion of background, existing technology, advances
in technology, and ongoing technology demonstrations. Published in June 2013, the
Technical Fact Sheet presents an overview of the geophysical classification technology
and process, the types of terrestrial sites where this technology may be applicable, and
data quality considerations. The Regulatory Fact Sheet, published in October 2014,
provides regulators a source of information about geophysical classification that clearly
explains what geophysical classification is, its benefits and limitations, and, most
importantly, the information and data that regulators need to monitor and evaluate its
use (October 2014, 14 pages). View or download at

ASTM Standard Guide for Selection of Passive Techniques for Sampling
Groundwater Monitoring Wells (D7929-14). The Standard describes three classes of
passive sampling technologies applicable for routine groundwater monitoring. The three
classes include diffusion-based samplers, sorption-based samplers, and passive grab
samplers. Wth the new ASTM Standard, passive groundwater sampling steps into the
mainstream with traditional purge sampling methods. Hard work from the ITRC Passive
Sampler team and others was key to completing this important milestone. For more

Research Brief 239: Remediation of Contaminated Groundwater by Persulfate.
TechDirect: December 1, 2014
4 of 7
clu-in.ora/newsletters

-------
Persulfate is a relatively inexpensive compound that is increasingly used for in situ
chemical oxidation (ISCO) of organic contaminants. ISCO is a way of cleaning up
groundwater by pumping an oxidizer such as persulfate into the contaminated
groundwater. The persulfate is converted into radicals, which are much more reactive,
that convert the hazardous chemicals into other compounds that are generally less toxic
and more easily degraded. Although persulfate's use has increased, there is still an
incomplete understanding of how it is converted into reactive radicals that degrade
hazardous chemicals. Findings from a new study provide insight into adding persulfate
to groundwater to breakdown organic contaminants, such as polychlorinated
biphenyls, 1,4-dioxane, and components of petroleum, that may be difficult to treat with
other methods and potentially harmful to human health.For more information, see
http://tools,niehs,nih,aov/srp/researchbriefs/view,cfm?Brief ID=239.
In Situ Biogeochemical Transformation Processes for Treating Contaminated
Groundwater. In situ biogeochemical transformation (ISBGT) refers to the abiotic
transformation of contaminants by iron minerals, which can occur naturally in the soil
matrix or be formed by microbial activity. ISBGT processes contribute to the natural
attenuation of chlorinated solvents in groundwater. ISBGT can be engineered in situ
and implemented for remediation via injection of liquid amendments or installation of
permeable reactive barriers. This fact sheet reviews the reaction chemistry,
contaminants of concern that can be treated by ISBGT, the site conditions that promote
abiotic transformation processes, key parameters for monitoring remedy performance,
and the potential for combining ISGBT with other remedial technologies (September
2014, 6 pages). View or download at

USGS Scientific Investigations Report 2014-5140: Hydrogeologic
Characterization and Assessment of Bioremediation of Chlorinated Benzenes
and Benzene in Wetland Areas, Standard Chlorine of Delaware, Inc. Superfund
Site, New Castle County, Delaware, 2009-12. This report describes the results of field
and laboratory investigations that occurred between 2009-12 for an ongoing wetland
study at the Standard Chlorine of Delaware Superfund site, Newcastle County,
Delaware, where major contaminants include trichlorobenzene and dichlorobenzene
isomers, chlorobenzene, and benzene. The goal of the wetland study is to assist the
EPA in identifying an effective remedial strategy for the contaminated groundwater and
sediment in the wetland areas. The major objectives included in the report are (1)
wetland characterization, including determination of the hydrogeology and the
distributions of groundwater contaminants and other geochemical constituents, and (2)
determination of biodegradation processes naturally occurring in the wetland sediment
and the effects of amendments to enhance biodegradation, including biostimulation and
bioaugmentation. An anaerobic consortium, called WBC-2, that was developed by the
USGS from wetland sediment at a site in Maryland to degrade chlorinated ethanes and
ethenes, was used for bioaugmentation testing in this study. View or download at
