> Grant Award

$11 Million in Supplemental Funds to Clean up and Redevelop Contaminated
Brownfields Sites Across the Country. The U.S. EPA announced $11 million in
supplemental funding to help clean up contaminated Brownfields properties. The
Revolving Loan Funds (RLF) will help 31 grantees carry out cleanup and
redevelopment projects. These projects are expected to create more than 700 jobs and
leverage over $57 million in cleanup and redevelopment, while utilizing unique
financing mechanisms and partnerships to protect people's health and the environment.
Revolving loan funds specifically supply funding for grant recipients to provide loans
and sub-grants to carry out cleanup activities at brownfield sites. When these loans are
repaid, the loan amount and any interest is then returned to the fund and subgranted or
re-loaned to other borrowers, providing an ongoing source of capital for brownfields
cleanup. The supplemental grants range in funding from about $200,000 to $500,000
with an average grant award of $350,000. For more information, see http://ciu-in.ora/rif09i4.

ITRC Soil Sampling and Decision Making Using Incremental Sampling
Methodology Parts 1 and 2 - September 9 and 16, 2014. This 2-part training course
along with ITRC's Web-based Incremental Sampling Methodology Technical and
Regulatory Guidance Document (ISM-1, 2012) is intended to assist regulators and
practitioners with the understanding the fundamental concepts of soil/contaminant
heterogeneity, representative sampling, sampling/laboratory error and how ISM
addresses these concepts. Through this training course you should learn: basic
principles to improve soil sampling results, systematic planning steps important to ISM,
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.

NARPM Presents...Decision Support System for Matrix Diffusion Modeling -
September 22, 2014,1:00PM-3:00PM EDT (17:00-19:00 GMT). The objective of this
internet seminar is to provide training on an accessible, easy-to-use, and useful tool for
modeling matrix diffusion. Low-permeability (low-k) zones can serve as indirect,
low-level sources of contamination to transmissive zones as a result of matrix diffusion.
The potential for matrix diffusion effects can be seen at virtually any site with
heterogeneity in the subsurface, dense non-aqueous phase liquids (DNAPL), or where
persistent contaminant concentrations in groundwater after source-zone remediation
have been observed. To better equip the community with accessible, useable, and
practical models for evaluating matrix diffusion effects, the Environmental Security
Technology Certification Program (ESTCP) funded development of the Matrix Diffusion
Toolkit. The Toolkit provides planning level estimates of the (1) mass discharge caused
by diffusion from a low-k diffusion-dominated unit into a high-permeability
advection-dominated unit (estimates of concentration and mass remaining in the
high-permeability unit, after the source is removed, are also provided); (2) contaminant
transport via advection and transverse diffusion in the transmissive layer; and (3)
transport via transverse diffusion in the low-k zone. Based on the Microsoft Excel
platform, the Toolkit is an easy-to-use, comprehensive, free software tool that can
assist site personnel to effectively and efficiently estimate the effects of matrix diffusion
at their site, and transfer the results to stakeholders. Furthermore, the software can
assist project managers in evaluating whether remediation goals are achievable in the
short term. For more information and to register, see http://ciu-in.ora/iive.

ITRC Biochemical Reactors for Treating Mining Influenced Water - September 23,
2014, 2:00PM-4:15PM EDT (18:00-20:15 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
Reactors for Mining-Influenced Water technology guidance (BCR-1, 2013). For more

ITRC Environmental Molecular Diagnostics: New Tools for Better Decisions -
September 24, 2014, 2:00PM-4:15PM EDT (18:00-20:15 GMT). Environmental
molecular diagnostics (EMDs) are a group of advanced and emerging analytical
techniques used to analyze biological and chemical characteristics of environmental
samples. Although EMDs have been used over the past 25 years in various scientific
fields, particularly medical research and diagnostic fields, their application to
environmental remediation management is relatively new and rapidly developing. The
ITRC Environmental Molecular Diagnostics Fact Sheets (EMD-1, 2011), ITRC
Environmental Molecular Diagnostics Technical and Regulatory Guidance (EMD-2,
2013) and this companion Internet-based training will foster the appropriate uses of
EMDs and help regulators, consultants, site owners, and other stakeholders to better
understand a site and to make decisions based on the results of EMD analyses. At the
conclusion of the training, learners will be able to determine when and how to use the

Porewater Concentrations and Bioavailability: How You Can Measure Them and
Why They Influence Contaminated Sediment Remediation - October 6, November
19, December 1,15, 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.

Technology News and Trends (EPA 542-N-14-002). This issue highlights
characterization and remediation strategies to address contaminants of emerging
concern (CECs), which are chemicals or materials characterized by a perceived,
potential, or real threat to human health or the environment or by a lack of published
health standards. CECs typically are associated with certain classes of products, as
ingredients or generated during processing or manufacturing, such as pharmaceuticals
and personal care items, steroids and hormones, and pesticides.A contaminant also
may be "emerging" due to the discovery of a new exposure pathway to humans, such
as vapor intrusion into buildings, or the development of a more stringent regulatory
standard. New toxicity information on frequent contaminants such as trichloroethylene
(TCE) and tetrachloroethylene (PCE), for example, can lead to re-emergence of
concern (Summer 2014). View at http://ciu-in.ora/tnandt/08i4.

ITRC Publishes New Guidance Document on Contaminated Sediments
Remediation. Remediation of contaminated sediments commonly targets the
complementary goals of protecting human health and the environment and restoring
impaired environmental resources to beneficial use. Remediating contaminated
sediment sites is challenging from a technical and risk-management perspective. A new
ITRC Web-based guidance document presents a remedy selection framework for
contaminated sediments to help project managers evaluate remediation technologies
and develop remediation alternatives based on site-specific data. General categories of
contaminated sediment remedial technologies covered in the guidance document
include monitored natural recovery (MNR) and enhanced monitored natural recovery
(EMNR), in situ treatment, capping (conventional and amended), and removal
(dredging and excavation). Additional factors that need to be considered as part of the

Research Brief: Developments toward Low-Cost, Unattended Vapor Intrusion
Monitoring. NIEHS Superfund Research Program (SRP)-funded scientists from the
chemical sensor company Seacoast Science are developing an inexpensive vapor
intrusion monitoring system. The system can operate repeatedly without user
intervention and detect typical vapor intrusion chemicals at low detection limits, allowing
many more sites to be monitored over longer periods. The newly developed Seacoast
Science vapor intrusion monitor is inexpensive compared to common laboratory
equipment, is portable for easy setup, and does not require compressed gases to
operate, making it safe to leave unattended. Scientists continue work to develop the
instrument so it can be manufactured for less than $2,000 and left operating unattended
for up to 12 months, during which it can run repeating sample collection and analysis
