ITRC Performance-based Environmental Management - August 26.

Performance-based environmental management (PBEM) is a strategic, goal-oriented
methodology that is implemented through effective planning and decision logic to reach
a desired end state of site cleanup. The goal of PBEM is to be protective of human
health and the environment while efficiently implementing appropriate streamlined
cleanup processes. This ITRC training presents an overview of what PBEM is, explains
how and when to implement it, and describes the issues that regulators are concerned
about throughout PBEM's implementation. Case studies will be presented to illustrate
successful PBEM projects. The course is valuable not only because PBEM is being
proposed and implemented at many federal and private sites throughout the country,
but also because PBEM provides an opportunity to enhance all site remediation. For

Treatment of Heavy Metals and Elimination of Sulfur with a Novel Sulfate
Reducing Permeable Reactive Barrier Containing ZVI - August 27. Acid mine
drainage and acid rock drainage contain sulfuric acid together with heavy metals.
Biological treatment often relies on sulfate reducing bacteria, which use organic

-------
electron donating substrates to enable bacteria to reduce sulfate to sulfide.
Subsequently, sulfides precipitate heavy metals. However, excess sulfides are
released from the treatment system, so the process is not very effective in removing
sulfur. Excess sulfides have oxygen demand, are corrosive and malodorous. A process
developed at the University of Arizona uses zero valent iron (ZVI) either alone or mixed
with organic substrates. The main advantage of using ZVI is that ferrous iron (Fe2+)
released from its corrosion will precipitate sulfides formed by sulfate reduction, thereby
avoiding the discharge of excess sulfides from the barrier system. For more information
and to register, see http://ciu-in.ora/studio .

Using High-resolution Piezocone to Determine Hydraulic Parameters and Mass
Flux Distribution - August 27. This seminar will cover the results of an ESTCP-funded
(www.estcp.ora') demonstration of the use of the high-resolution piezocone direct push
sensor probe to determine direction and rate of ground water flow in three dimensions.
Field hydraulic measurements can be used to determine seepage velocity distributions
through interpolation methods recently incorporated into Groundwater Modeling
System. Probe data comprised of soil type and co-located hydraulic information is
particularly amenable to innovative data fusion based interpolations available through
the modeling platform. Following chemical concentration data collection, these
innovative data processing approaches allow for the determination of flux distributions
at resolutions and spatial configurations never before available. Field scale data
collection, interpolation, and modeling results will be presented and discussed. The
final technical report for the ESTCP demonstration can be found at

A Systematic Approach for Evaluation of Capture Zones at Pump and Treat
Systems - September 11 and October 8. This seminar presents a systematic
approach for the evaluation of capture zones at pump and treat systems, and provides
an overview of a recently published USEPA document on the topic (EPA 600/R-08/003,
January 2008). The target audience is project managers who review those analyses
and/or make decisions based on these types of analyses. This course will highlight: the
importance of capture zone analysis during ground water remediation, particularly for
sites requiring containment; key concepts of capture, such as "target capture zones"
and "converging lines of evidence;" and typical errors made in capture zone analysis.
Examples will be used to demonstrate key aspects of capture zone analysis. For more

In Situ Bioremediation of Chlorinated Ethene: DNAPL Source Zones
(BioDNAPL-3). This publication systematically lays out the technical and related
regulatory considerations for in situ bioremediation (ISB) of chlorinated ethene dense
DNAPL source zones, providing information related to site characterization
requirements, treatment system application and design criteria, process monitoring, and
process optimization. The ability of ISB technology to enhance the dissolution and
desorption of nonaqueous-phase contaminants to the aqueous phase, where they can
be degraded by the microbial population, depends on the spatial distribution of DNAPL
mass in the subsurface (e.g., pool/ganglia ratio) and the ability to deliver amendments
throughout this architecture (June 2008, 138 pages). View or download at

-------
organic compound content of tree cores is an inexpensive, rapid, and simple approach
to examining the distribution of subsurface volatile organic compound contaminants.
The method has been shown to detect several volatile petroleum hydrocarbons and
chlorinated aliphatic compounds associated with vapor intrusion and ground-water
contamination. Tree cores, which are approximately 3 inches long, are obtained by
using an increment borer. The cores are placed in vials and sealed. After a period of
equilibration, the cores can be analyzed by headspace analysis gas chromatography.
Because the roots are exposed to volatile organic compound contamination in the
unsaturated zone or shallow ground water, the volatile organic compound
concentrations in the tree cores are an indication of the presence of subsurface volatile
organic compound contamination.Thus, tree coring can be used to detect and map
subsurface volatile organic compound contamination. (July 2008, 72 pages). View or

Technology News and Trends (EPA 542-N-08-004). This issue highlights innovative
approaches to remediate and reclaim former mining sites and larger areas impacted by
abandoned mining sites. Environmental problems associated with mine-scarred lands
include revegetation difficulties, waste piles or dumps contributing to metal-loading in
surface water, and acid mine drainage (AMD) deteriorating regional surface and ground
water quality (July 2008, 6 pages). View or download at http://ciu-in.ora/techpubs.htm .

Approach to Vapor Intrusion at Contaminated Dry Cleaner Sites: A Survey of
Member States. Contaminant movement into buildings due to vapor migration from
volatile organic chemical (VOC) contamination in soil and groundwater has become a
significant concern to the public, business and regulatory agencies. Dry cleaning
operations use a number of VOCs that, if released to the soil and groundwater, can
lead to vapor migration into buildings and pose a health threat to people. This paper
summarizes responses to a short survey conducted in 2007 regarding how State
Coalition for Remediation of Drycleaners (SCRD)-represented states approach vapor
migration investigation, mitigation, and site closure at contaminated drycleaner
properties. The survey is intended to begin a dialogue regarding state approaches to
vapor migration at drycleaners (August 2008, 10 pages). View or download at
