Progress in Research: Reducing Exposure to Mercury, Arsenic, and Asbestos -
July 9, 2015, 1:00PM-3:00PM EDT (17:00-19:00 GMT). This Superfund Research
Program (SRP) Progress in Research webinar highlights exciting research from two
SRP Centers.Scientists at the Dartmouth College SRP Center are working to reduce
exposures to arsenic and mercury and to better understand how exposure to these
contaminants leads to disease. You will also hear from scientists at the University of
Pennsylvania SRP Center who are conducting research on asbestos waste, and how
that waste affects health. For more information and to register, see httn://ciu-in.om/iive.

ITRC Integrated DNAPL Site Strategy - July 16, 2015,1:00PM-3:15PM EDT
(17:00-19:15 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 httev/wwwjtrewebjora or httEV/cjuHrvorcj/yv^.

ITRC Remedy Selection for Contaminated Sediments - July 21, 2015,
1:00PM-3:15PM EDT (17:00-19:15 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

ITRC Integrated DNAPL Site Characterization - July 23, 2015,1:00PM-3:15PM EDT
(17:00-19:15 GMT). The Integrated DNAPL Site Characterization Team has
synthesized the knowledge about dense nonaqueous phase liquid (DNAPL) site
characterization and remediation acquired over the past several decades, and has
integrated that information into a new document, Integrated DNAPL Site
Characterization and Tools Selection (ISC-1, 2015). This guidance is a resource to
inform regulators, responsible parties, other problem holders, consultants, community
stakeholders, and other interested parties of the critical concepts related to
characterization approaches and tools for collecting subsurface data at DNAPL sites.
After this associated training, participants will be able to use the guidance to develop
and support an integrated approach to DNAPL site characterization, including: identify
what site conditions must be considered when developing an informative DNAPL
conceptual site model (CSM); define an objectives-based DNAPL characterization
strategy; understand what tools and resources are available to improve the
identification, collection, and evaluation of appropriate site characterization data; and
navigate the DNAPL characterization tools table and select appropriate technologies to
fill site-specific data gaps. For more information and to register, see http://www.itrcweb.ora

Technology News and Trends (EPA 542-N-14-005). This issue highlights innovative
approaches for remediating sites that are contaminated due to the presence of
mining-influenced water or solid waste associated with the mining of hard rock, coal or
uranium. Mining operations, both past and ongoing, can create a host of contamination
issues, including the release of contaminants of concern such as arsenic, cadmium,
copper, lead and zinc, into soil and groundwater. Much of the contamination is
associated with acid rock drainage generated when surface water or groundwater
comes into contact with acid-generating mine wastes or with bedrock exposed by
mining processes.The projects featured in this issue illustrate the collaboration between
federal partners, such as the U.S. Bureau of Land Management, EPA and Forest
Service, and state agencies, tribes and other stakeholders, to find solutions for mining
sites and identify cost-effective and low-maintenance treatment systems for mine site
cleanups (Spring 2015). View at http://ciu-in.ora/tnandt/0515.

EPA Issues Vapor Intrusion Technical Guides. The U.S. EPA has issued two
technical guides to support vapor intrusion assessment and mitigation activities. The
Technical Guide for Assessing and Mitigating the Vapor Intrusion Pathway from
Subsurface Vapor Sources to Indoor Air applies to all sites being evaluated under
federal land cleanup statutes by EPA, other federal agencies, state and tribal
governments and brownfield grantees. A companion document, the Technical Guide
for Addressing Petroleum Vapor Intrusion at Leaking Underground Storage Tank Sites
addresses any sites where vapor intrusion related to petroleum contamination from
underground storage tanks is a potential concern. Both guides are applicable to
residential and non-residential settings. View or download at

www.epa.gov/oswer/vaporintrusion/quidance.html.

2015 Revised Underground Storage Tank Regulations. In June 2015, EPA issued
the 2015 underground storage tank regulation and the 2015 state program approval
regulation. The revisions strengthen the 1988 federal underground storage tank (UST)
regulations by increasing emphasis on properly operating and maintaining UST
equipment. The revisions will help prevent and detect UST releases, which are a
leading source of groundwater contamination. The revisions will also help ensure all
USTs in the United States, including those in Indian country, meet the same minimum
standards. This is the first major revision to the federal UST regulations since 1988.
