EPA's Study of the Potential Impacts of Hydraulic Fracturing on Drinking Water
Resources: A Progress Report - January 3 and 4, 2013. On December 18, 2012,
the U.S. Environmental Protection Agency (EPA) released a report highlighting the
progress it has made on its national study to understand the potential impacts of
hydraulic fracturing on drinking water resources.This webinar will provide
project-specific updates that include research approach, status, and next steps. EPA
will also provide updates on the five technical Roundtables held in November 2012. For
more information and to register, see http://ciu-in.ora/iive .

ITRC Integrated DNAPL Site Strategy, January 8, 2013, 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 measureable; 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 Development of Performance Specifications for Solidification/Stabilization -
January 10, 2013,11:00AM-1:15PM EST (16:00-18:15 GMT). The ITRC technical and
regulatory guidance document Development of Performance Specifications for
Solidification/Stabilization (S/S-1, 2011) and associated Internet-based training provide
an approach to assist practitioners and regulators with measuring and determining
acceptable S/S performance. This approach developed by the ITRC
Solidification/Stabilization Team provides information for developing, testing, and
evaluating appropriate site-specific performance specifications and the considerations
for designing appropriate long-term stewardship programs. In addition, the approach

provides useful tools for establishing an appropriate degree of treatment and regulatory
confidence in the performance data to support decision-making. This training and
guidance is intended to be beneficial to anyone involved with CERCLA, RCRA,
Brownfields, UST or any other regulatory program where S/S has been selected or
implemented as a remedial technology. For more information and to register, see

ITRC Mining Waste Treatment Technology Selection - January 15, 2013,
2:00PM-4:15PM EST (19:00-21:15 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 A Decision Framework for Applying Attenuation Processes to Metals and
Radionuclides - January 17, 2013,11:00AM-1:15PM EST (16:00-18:15 GMT). This
training and the associated ITRC Technical and Regulatory Guidance document, A
Decision Framework for Applying Attenuation Processes to Metals and Radionuclides
(APMR-1, 2010), is intended for anyone involved with evaluating, investigating,
remediating or managing a site that involves metal and radionuclide contaminants in
groundwater. This training and document provides: introduction to key attenuation
processes for metals and radionuclides, information on incorporating Monitored Natural
Attenuation (MNA) into remedial alternatives for metals/rads, and an overview of the
decision framework on MNA for metals and radionuclides in groundwater within the
larger evaluation framework of a contaminated site. For more information and to

Superfund Research Program (SRP) Funding Opportunities Web Seminar -
January 30, 2013,1:30PM-3:00PM EST (18:30-20:00 GMT). The SRP will be holding
a web seminar to provide information about current "Superfund Hazardous Substance
Research and Training Program (P42)" funding opportunities. Primary focus will be on
the new multi-project center grant announcement (P42), including an emphasis on
changes compared to previous solicitations. Participants will have an opportunity to ask
questions. For more information and to register, see http://ciu-in.ora/iive .

Technology News and Trends (EPA 542-N-12-006). This issue highlights the use of

in situ bioremediation to address groundwater contamination caused by past releases
of organic contaminants. Implementation of bioremediation at these sites involves
biostimulation techniques, in which amendments are administered to the subsurface to
provide nutrition for microorganisms capable of consuming and consequently
biodegrading the contaminants, as well as bioaugmentation techniques involving
subsurface injection of biodegrading microorganisms that may not already exist onsite

Optimization Review: Fairfield Coal Gasification Plant Superfund Site, Fairfield,
Iowa (EPA 542-R-12-004). This document provides project background and
information about the optimization review conducted at the Fairfield Coal Gasification
Plant Superfund Site, including information about site-specific background; the
conceptual site model; optimization findings related to source structures and impacted
soil removal, the dissolved phase groundwater plume, and establishment of technical
impracticability waivers; and optimization recommendations related to improving
effectiveness, reducing cost, technical improvement, and site closure (August 2012).
