Stable Isotope Analyses to Understand the Degradation of Organic Contaminants in Ground Water (Part 1) – U.S. EPA Technology Innovation and Field Services Division
September 9, 2010, 2:00PM-3:30PM EDT, 18:00-19:30 GMT
When organic contaminants such as benzene, TCE or MTBE are degraded, the ratio of the stable isotopes of carbon in the organic contaminants will often change in a predictable fashion. In the last ten years, advances in analytical chemistry have made it possible to measure these changes, even when the organic contaminants are present in water at low concentrations. A determination of the ratio of the stable isotopes can reveal whether the contaminant has been degraded. If the mechanism of degradation is understood, and laboratory studies are available that define the relationship between the extent of degradation of the contaminant and the shift in the ratio of isotopes, it is often possible to estimate the extent of biodegradation of the contaminant.

This webinar will briefly review the theory behind isotopic effects, it will explain the units used to characterize the ratio of isotopes, and it will discuss the simple mathematics that can relate the shift in the ratio to the extent of degradation. Then the webinar will illustrate an approach to estimate rate constants for natural biodegradation of contaminants in ground water. The isotope analysis will be used to estimate the extent of natural biodegradation of MTBE at a gasoline spill site. The extent of biodegradation will be combined with the hydrological parameters at the site to estimate rate constants for biodegradation.

The webinar will conclude with a number of cautions and warnings. Heterogeneity in flow paths in the aquifer and proximity to NAPL or other source of contamination to ground water can substantially confuse the interpretation of stable isotope data. Both these conditions cause the isotope analysis to underestimate the extent of degradation. Heterogeneity in the rate of biodegradation can produce substantial errors in the forecasts of plume behavior. The webinar will provide recommendations to deal with the effects of heterogeneity in rates of biodegradation.

U.S. EPA has released A Guide for Assessing Biodegradation and Source Identification of Organic Ground Water Contaminants using Compound Specific Isotope Analysis (CSIA) [EPA 600/R-08/148 | December 2008 | www.epa.gov/ada]. The Guide provides recommendations for sample collection, sample preservation, and sample analysis; recommendations on QA/QC issues; details on calculations; and a catalogue of expected initial values for the ratios of ¹³C to ¹²C in organic compounds such as TCE and PCE. The Guide also illustrates in detail the process to use isotope ratio data to estimate rate constants for degradation of organic compounds in ground water.

Note: This is a repeat of the June 16, 2010 seminar on this topic split across two sessions. You will be registered for each of the two sessions in this series and will receive a separate registration confirmation email for each session. Part 2 will be offered on September 16, 2010, 2:00 PM - 3:30 PM, EDT (18:00-19:30 GMT).

Biological-based Assays - Indicators of Ecological Stress – National Institute of Environmental Health Sciences, Superfund Research Program
September 23, 2010, 2:00PM-4:00PM EDT, 18:00-20:00 GMT
This seminar will feature Dr. Bruce Duncan, Senior Ecologist with EPA Region 10's Office of Environmental Assessment, and Dr. Jim Shine, Associate Professor of Aquatic Chemistry at Harvard University's Center for the Environment and part of the Harvard School of Public Health Superfund Research Program.

Dr. Duncan and EPA Region 10 have been assisting the NIEHS Superfund Research Program for many years. Part of recent support has been through the National Bioassay Project, a consortium of existing research centers focused on developing and crosswalking a suite of tests to evaluate complex mixtures in sediments. The consortium includes Texas A&M University, Duke University, Michigan State University, University of California - Davis, and University of California - San Diego with advice from the EPA Ecological Risk Assessors Forum.

As an ancillary to that project, detailed work on evaluating organism exposures to contaminants was conducted at a Superfund Site (Lower Duwamish Waterway) in Seattle, WA. A 2009 exposure study led largely by Matt Kelley (Texas A&M, now with LSU Health Sciences Center-Shreveport) and supported by EPA, Texas A&M, Southern California Coastal Water Research Project, and NOAA looked at the concordance between media concentrations, biomarker response, and bioaccumulation of PCBs and PAHs at several locations. Fish, mussels, and solid phase micro extraction devices (SPMEs) were placed in cages at two heights. SPMEs have been extracted for PAHs, PCBs, and pesticides. Sediment, water, mussels, and fish have been analyzed for PAHs and (except for water) are awaiting PCB analysis. In addition, mussel survival and growth were measured. The two vertical locations give some insight into the influence of the bottom sediment and contaminant flux from sediments on exposure at the sediment/water interface. The mussel accumulation and growth allow a field evaluation of concordance with SPMEs. Dr. Duncan's presentation will give an overview of this project.

Dr. Shine's presentation will focus on the "Gellyfish" sampling tool. The "Gellyfish", an in-situ equilibrium-based sampling tool for determining multiple free metal ion concentrations in aquatic systems, has been developed and refined under both laboratory and field conditions. The device is based on the equilibrium partitioning between free metal ions in the surrounding solution and iminodiacetate binding groups held within the gel matrix of the sampler. Ninety percent equilibration (t₉₀) is achieved in approximately 26 hours. Apparent stability constants were measured for the binding of Cu, Zn, Pb, Ni, and Cd to the Gellyfish, allowing us to estimate their free metal ion concentrations in the surrounding solution. An accompanying computer model (GELLYMOD) was also developed to account for metal-metal competition for uptake into the sampler. Subsequent competition experiments involving two or three metals were performed to validate the computer model. The results suggested the use of the Gellyfish sampler, in conjunction with the model we developed, is a valid approach for accurately quantifying free metal ion levels in metal mixtures within environmentally relevant concentration ranges. Compared to other analytical methods for free metal ions, the Gellyfish sampler is inexpensive, rapid, reusable, easy to use, and can measure multiple metals simultaneously, thus permitting the generation of adequate quantities of data to examine spatial and temporal variability and other factors affecting metal speciation.

Superfund Revelopment Seminar Series – U.S. EPA, Office of Solid Waste and Emergency Response, Office of Superfund Remediation and Technology Innovation
September 30, 2010, 2:00PM-4:00PM EDT, 18:00-20:00 GMT
The Superfund Redevelopment Initiative has developed a new alternative energy pre-feasibility analysis process for Superfund sites. This process, which often involves economic analysis and GIS mapping components, serves as an initial step to determine if a Superfund property could support alternative energy projects. The presentation will highlight two sites: the Iron King Mine Humboldt Smelter site and the Apache Powder Company site in Arizona at which SRI has provided site stakeholders with pre-feasibility analyses. Key stakeholders at these sites were interested in determining if alternative energy production were viable reuses. Presenters will walk participants through the steps involved in conducting the pre-feasibility analysis, paying particular attention to how stakeholder concerns were addressed, outcomes of the analyses and important lessons learned.

Protocol for Use of Five Passive Samplers – Interstate Technology and Regulatory Council
September 14, 2010, 2:00PM-4:15PM EDT, 18:00-20:15 GMT
All groundwater samplers or sampling methodologies attempt to collect a well-water sample which is representative of the groundwater adjacent to the well. The ITRC Passive Sampler Team has defined a passive groundwater sampler as one that is able to acquire a sample from a discrete position in a well without active media transport induced by pumping or purge techniques. Passive sampling is synonymous with no-purge sampling and can be used as a substitute or replacement for any current groundwater sampling technology. Passive samplers have been used in every state in the U.S. and in many other countries. Passive samplers are relatively easy to use; eliminate purge-water production (therefore, there is little or no disposal cost); reduce field sampling variability resulting in highly reproducible data; decrease field labor and project management costs for long-term monitoring; allow rapid field sample collection; sample discrete intervals in a well; are practical for use where access is difficult or discretion is desirable; can be deployed in series to provide a vertical contaminant profile; and have virtually no depth limit.

This training supports the understanding and use of the ITRC Protocol for Use of Five Passive Samplers to Sample for a Variety of Contaminants in Groundwater (DSP-5, 2007). The five technologies included in this document include diffusion samplers (Regenerated Cellulose Dialysis Membrane Sampler and Rigid Porous Polyethylene Sampler), equilibrated grab samplers (Snap Sampler™ and HydraSleeve™ Sampler); and an accumulation sampler (GORE™ Module). The training starts with information common to all five samples then focuses on each sampler as instructors describe the sampler and explain how it works; discuss deployment and retrieval of the sampler; highlight advantages and limitations; and present results of data comparison studies.

Phytotechnologies – Interstate Technology and Regulatory Council
September 16, 2010, 11:00AM-1:15PM EDT, 15:00-17:15 GMT
Phytotechnologies is a set of technologies using plants to remediate or contain contaminants in soil, groundwater, surface water, or sediments. These technologies have become attractive alternatives to conventional cleanup technologies due to relatively low capital costs and the inherently aesthetic nature of planted sites.

This training familiarizes participants with ITRC's Phytotechnology Technical and Regulatory Guidance and Decision Trees, Revised (Phyto-3, 2009). This document provides guidance for regulators who evaluate and make informed decisions on phytotechnology work plans and practitioners who have to evaluate any number of remedial alternatives at a given site. This document updates and replaces Phytoremediation Decision Tree (Phyto-1, 1999) and Phytotechnology Technical and Regulatory Guidance Document (Phyto-2, 2001). It has merged the concepts of both documents into a single document. This guidance includes new, and more importantly, practical information on the process and protocol for selecting and applying various phytotechnologies as remedial alternatives.

This guidance contains decision trees:

Remedy Selection Decision Tree
Groundwater Decision Tree
Soil/Sediment decision Tree
Riparian Zone Decision Tree

This course will be most useful to you if you download the guidance and follow the discussion with the Decision Trees displayed in your guidance. Our instruction is how to use the Guidance - not how to use the decision trees process. That is explained within the Guidance.

In Situ Bioremediation of Chlorinated Ethene - DNAPL Source Zones – Interstate Technology and Regulatory Council
September 30, 2010, 11:00AM-1:15PM EDT, 15:00-17:15 GMT
Treatment of dissolved-phase chlorinated ethenes in groundwater using in situ bioremediation (ISB) is an established technology; however, its use for DNAPL source zones is an emerging application. This training course supports the ITRC Technical and Regulatory Guidance document In Situ Bioremediation of Chlorinated Ethene: DNAPL Source Zones (BioDNAPL-3, 2008). This document provides the regulatory community, stakeholders, and practitioners with the general steps practitioners and regulators can use to objectively assess, monitor, and optimize ISB treatment of DNAPL source zones. The objective is to provide adequate technology background for the user to understand the general and key aspects of ISB for treatment of chlorinated ethene DNAPL source zones. It is not intended to be a step-by-step instruction manual for remedial design, but describes technology-specific considerations for application of ISB of DNAPL source zones.

For this training and guidance document, a DNAPL source zone includes the zone that encompasses the entire subsurface volume in which DNAPL is present either at residual saturation or as "pools" that accumulate above confining units. The DNAPL source zone includes regions that have come into contact with DNAPL and may be storing contaminant mass as a result of diffusion of DNAPL into the soil matrix. Even though DNAPLs may be present in both the unsaturated and saturated zones, the discussion of ISB of DNAPL source zones in this training and guidance document focuses on treatment of DNAPL source zones within the saturated zone.

Two goals of any DNAPL source treatment technology are to 1) reduce the mass of contaminants within the source area and 2) prevent migration of contaminants above unacceptable levels. The enhanced ISB technology reduces source mass and controls flux through the enhanced dissolution and desorption of DNAPL constituents into the aqueous phase, and subsequent microbially mediated degradation processes. Although enhanced ISB of DNAPL source zones has been demonstrated in the field at a few chlorinated solvent sites, expectations for rapid depletion of the source zone must be realistic. This training and guidance provide detailed requirements necessary to support the realistic determination of goals for ISB of a DNAPL source zone.

To get the most out of this training, before the class, please review the associated document, the ITRC Technical and Regulatory Guidance document In Situ Bioremediation of Chlorinated Ethene: DNAPL Source Zones (BioDNAPL-3, 2008).

Perchlorate Remediation Technologies – Interstate Technology and Regulatory Council
October 7, 2010, 11:00AM-1:15PM EDT, 15:00-17:15 GMT
Perchlorate contamination exists in water and soil, and occurs widely throughout the United States. Public awareness and concern regarding perchlorate has increased in recent years. Perchlorate occurrence in drinking water and food supplies is a human health concern because it can interfere with iodide uptake by the thyroid gland and result in decreased thyroid hormone production. The ITRC Perchlorate Team was formed in 2004 to address technical issues associated with perchlorate. Many technologies are available to remediate perchlorate contamination, but only a few are commonly used.

This training introduces state regulators, environmental consultants, site owners, and community stakeholders to Remediation Technologies for Perchlorate Contamination in Water and Soil (PERC-2, 2008), created by ITRC's Perchlorate Team to assist reviewers in assessing the adequacy of perchlorate remediation projects. This course gives the student a background in the available remediation technologies to treat perchlorate contamination, discusses emerging technologies, and presents case studies of applications.

The first document produced by the ITRC Perchlorate Team, Perchlorate: Overview of Issues, Status, and Remedial Options (PERC-1, 2005) and associated Internet-based training provide regulators and other stakeholders a basic overview of a broad spectrum of information regarding perchlorate sources, sampling and analysis techniques, a discussion of risk issues, risk management strategies and regulatory status, and included a brief summary of remediation technologies. It is recommended that the registrant review the Perchlorate: Overview of Issues, Status, and Remedial Options (PERC-1, 2005) document and associated Internet-based training archive (available from http://www.itrcweb.org/ibt.asp#Perchlorate_CurrentInfo) for more information.

An Improved Understanding of LNAPL Behavior in the Subsurface - State of Science vs. State of Practice – Interstate Technology and Regulatory Council
October 12, 2010, 2:00PM-4:15PM EDT, 18:00-20:15 GMT
Light non-aqueous phase liquids (LNAPLs) are organic liquids such as gasoline, diesel, and other petroleum hydrocarbon products that are immiscible with water and less dense than water. Understanding LNAPLs is important because they are present in the subsurface at thousands of remediation sites across the country, and are often the sole reason why a site remains "open." The spectrum of sites where LNAPL assessment and remediation efforts may take place include petroleum manufacturing and handling facilities such as refineries, bulk product terminals, gas stations, airports and military bases. LNAPLs in the subsurface can be a complex problem to address, and frequently prevent or delay regulatory closure (no further action) of remediation projects.

This training course is relevant for all levels of state and federal regulators, environmental consultants, and technically-inclined site owners and public stakeholders. The training course is divided into three parts:

An Improved Understanding of LNAPL Behavior in the Subsurface - State of Science vs. State of Practice
LNAPL Characterization and Recoverability -- Improved Analysis
Evaluating LNAPL Remedial Technologies for Achieving Project Goals

Part 1 explains how LNAPLs behave in the subsurface and examines what controls their behavior. Part 1 also explains what LNAPL data can tell you about the LNAPL and site conditions. Relevant and practical examples are used to illustrate key concepts. A sound LNAPL understanding is necessary to effectively characterize and assess LNAPL conditions and potential risks, as well as to evaluate potential remedial technologies or alternatives. Unfortunately, many environmental professionals have a faulty understanding of LNAPL conditions based on outdated paradigms. The ITRC LNAPLs Team is providing Internet-based training to improve the general understanding of LNAPLs. Better understanding leads to better decision making. Additionally, this training provides a necessary technical foundation to foster effective use of the ITRC LNAPLs Team Technical and Regulatory Guidance document, Evaluating LNAPL Remedial Technologies for Achieving Project Goals (LNAPL-2, 2009).

Part 2 addresses LNAPL characterization and site conceptual model development as well as LNAPL recovery evaluation and remedial considerations. Specifically, Part 2 discusses key LNAPL and site data, when and why those data may be important, and how to get those data. Part 2 also discusses how to evaluate LNAPL recoverability. A sound LNAPL understanding is necessary to effectively characterize and assess LNAPL conditions and potential risks, as well as to evaluate potential remedial technologies or alternatives.

Evaluating LNAPL Remedial Technologies for Achieving Project Goals – Interstate Technology and Regulatory Council
October 14, 2010, 2:00PM-4:15PM EDT, 18:00-20:15 GMT
Light non-aqueous phase liquids (LNAPLs) are organic liquids such as gasoline, diesel, and other petroleum hydrocarbon products that are immiscible with water and less dense than water. Understanding LNAPLs is important because they are present in the subsurface at thousands of remediation sites across the country and are often the sole reason why a site remains open.

LNAPLs in the subsurface can be a complex problem to address, and frequently prevent or delay regulatory closure (no further action) of remediation projects.

Over the past few decades, LNAPL remedial technologies have evolved from conventional pumping or hydraulic recovery systems to a variety of innovative, aggressive, and experimental technologies that address the mobile and residual LNAPL fractions, as well as volatile and dissolved-phase plumes. Thus, many different LNAPL remedial technologies with differing site and LNAPL applicabilities and capabilities are available to remediate LNAPL releases. This can make selection of a remedial technology daunting and inefficient. To foster informed remedial technology selection and appropriate technology application, the LNAPLs Team developed the ITRC Technical and Regulatory Guidance document, Evaluating LNAPL Remedial Technologies for Achieving Project Goals (LNAPL-2, 2009). This document addresses seventeen LNAPL remedial technologies and provides a framework to streamline remedial technology evaluation and selection.

This training course is relevant for new and veteran regulators, environmental consultants, and technically-inclined site owners and public stakeholders. The training course is divided into three parts:

Part 1: An Improved Understanding of LNAPL Behavior in the Subsurface - State of Science vs. State of Practice
Part 2: LNAPL Characterization and Recoverability - Improved Analysis
Part 3: Evaluating LNAPL Remedial Technologies for Achieving Project Goals

Part 3 uses the LNAPL conceptual site model (LCSM) approach to identify the LNAPL concerns or risks and set proper LNAPL remedial objectives and technology-specific remediation goals and performance metrics. The training course also provides an overview of the LNAPL remedial technology selection framework. The framework uses a series of tools to screen the seventeen remedial technologies based on site and LNAPL conditions and other important factors. LNAPL Training Part 1 and LNAPL Training 2 are recommended pre-requisites for this Part 3 training course.

Use of Risk Assessment in Management of Contaminated Sites – Interstate Technology and Regulatory Council
October 19, 2010, 2:00PM-4:15PM EDT, 18:00-20:15 GMT
The ITRC Risk Assessment Resources team developed a document titled Use of Risk Assessment in Management of Contaminated Sites (RISK-2, 2008). This Internet-based training is taken from the RISK-2 document and highlights variation of risk-based site management and how to improve the use of risk assessment for making better risk management decisions. This training course looks at how various risk-based approaches and criteria are applied in various states and programs throughout the processes of screening, characterization, and management of contaminated sites.

The document and training course are intended for risk assessors and project managers involved with the characterization, remediation, and/or re-use of sites. Together they provide a valuable tool for federal and state regulatory agencies to demonstrate how site data collection, risk assessment, and risk management may be better integrated. This training course explains:

Variation in risk assessment parameters/approaches in various states and their influence on risk management
Insights into the use of risk assessment in risk management process through use of specific case study examples
An improved process of using risk assessment in risk management

This course builds on the Risk Team's previous work identifying variation in the development of risk-based numerical criteria, specifically soil screening levels. A prerequisite to this training course is the Risk Team's previous Internet-based training (archive is available from http://cluin.org/live/archive.cfm?sort=title#itrc) based on ITRC's Risk Assessment and Risk Management: Determination of Risk-Based Values (RISK-1, 2005). The Electronic Risk Resource Sheet published by the ITRC Risk Team is recommended as an excellent resource for supplemental materials related to risk assessment and risk management.

Enhanced Attenuation of Chlorinated Organics: A Site Management Tool – Interstate Technology and Regulatory Council
October 21, 2010, 11:00AM-1:00PM EDT, 15:00-17:00 GMT
Many sites with chlorinated organic contamination in groundwater have gone through extensive remedial evaluations and actions. After years of operating high energy processes, their effectiveness has begun to diminish without remedial objectives being met. Other effective remedial alternatives can be applied; however, there are difficulties transitioning these sites from these high energy systems to other low energy remedial alternatives and eventually to Monitored Natural Attenuation (MNA).

This training on the ITRC Technical and Regulatory Guidance for Enhanced Attenuation: Chlorinated Organics (EACO-1, 2008) describes the transition (the bridge) between aggressive remedial actions and MNA and vise versa. Enhanced attenuation (EA) is the application of technologies that minimize energy input and are sustainable in order to reduce contaminant loading and/or increase the attenuation capacity of a contaminated plume to progress sites towards established remedial objectives. Contaminant loading and attenuation capacity are fundamental to sound decisions for remediation of groundwater contamination. This training explains how a decision framework which, when followed, allows for a smooth transition between more aggressive remedial technologies to sustainable remedial alternatives and eventually to Monitored Natural Attenuation. This training will demonstrate how this decision framework allows regulators and practitioners to integrate Enhanced Attenuation into the remedial decision process.

As our experience and knowledge grows around the implementation of MNA, the EA process will be considered an important management tool for optimizing site remedies and moving sites to final completion. This approach is consistent with the current regulatory environment and can be accommodated within a broad range of regulatory programs such as CERCLA and State dry cleaner regulations. This new framework and decision process will accelerate the environmental clean-up progress on a national scale and reduce overall costs, while still providing protection to human health and the environment.

For reference during the training class, participants should download and print a copy of the decision flow chart, Figure 2-1 on page 10 of the ITRC Technical and Regulatory Guidance for Enhanced Attenuation: Chlorinated Organics (EACO-1, 2008) and available as a 1-page PDF at http://www.cluin.org/conf/itrc/eaco/ITRC-EACO-DecisionFlowchart.pdf.
