Slides for "Soil Sampling and Decision Making Using Incremental Sampling Methodology - Part 1," May 8, 2012

training@itrcweb.org (the ITRC Training Program) — Tue, 8 May 2012 23:00:00 GMT

When sampling soil at potentially contaminated sites, the goal is collecting representative samples which will lead to quality decisions. Unfortunately traditional soil sampling methods don't always provide the accurate, reproducible, and defensible data needed. Incremental Sampling Methodology (ISM) can help with this soil sampling challenge. ISM is a structured composite sampling and processing protocol that reduces data variability and provides a reasonable estimate of a chemical's mean concentration for the volume of soil being sampled. The three key components of ISM are systematic planning, field sample collection, and laboratory processing and analysis. The adequacy of ISM sample support (sample mass) reduces sampling and laboratory errors, and the ISM strategy improves the reliability and defensibility of sampling data by reducing data variability. ISM provides representative samples of specific soil volumes defined as Decision Units. An ISM replicate sample is established by collecting numerous increments of soil (typically 30 to 100 increments) that are combined, processed, and subsampled according to specific protocols. ISM is increasingly being used for sampling soils at hazardous waste sites and on suspected contaminated lands. Proponents have found that the coverage afforded by collecting many increments, together with disciplined processing and subsampling of the combined increments, yields consistent and reproducible results that in most instances have been preferable to the results obtained by more traditional (e.g. discrete) sampling approaches. 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 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). You will also be provided with links to additional resources related to ISM. The intended users of this guidance and training course are state and federal regulators, project managers, and consultant personnel responsible for and/or directly involved in developing, identifying or applying soil and sediment sampling approaches and establishing sampling objectives and methods. In addition, data end users and decision makers will gain insight to the use and impacts of ISM for soil sampling for potentially contaminated sites. Recommended Reading: We encourage participants to review the ITRC ISM document(http://www.itrcweb.org/ISM-1/) prior to participating in the training classes. If your time is limited in reviewing the document in advance, we suggest you prioritize your time by reading the Executive Summary, Chapter 4 "Statistical Sampling Designs for ISM," and Chapter 7 "Making Decisions Using ISM Data" to maximize your learning experience during the upcoming training classes.

Slides for "Superfund Research Program Sediment Bioavailability Assays - Kick-off Webinar Featuring New Research Projects," May 7, 2012

cranej2@niehs.nih.gov (Justin Crane) — Mon, 7 May 2012 23:00:00 GMT

This webinar will be comprised of 5 short presentations from the Superfund Research Program Individual Research Grants (R01). The NIEHS Superfund Research Program (SRP) released a funding opportunity announcement in 2010 titled RFA ES-11-005 "Innovative Bioavailability Assays to Assess the Effectiveness of Contaminated Sediment Remediation (R01)." This solicitation called for the development of innovative assays of bioavailability that may be used to determine the effectiveness of sediment remediation in reducing risks to humans. The ultimate goals of this solicitation are two-fold: first, to develop and introduce new tools to assess whether remediation efforts are protective of human health; and second, to increase use of bioavailability in risk assessment through providing scientifically-valid, practical, and cost-effective tools. In response to this solicitation, five three-year awards were made in 2011.

Slides for "Green & Sustainable Remediation," Apr 26, 2012

training@itrcweb.org (the ITRC Training Program) — Thu, 26 Apr 2012 23:00:00 GMT

The ultimate goal of remediation systems is to protect human health and the environment from contaminants. Historically, remedies have been implemented without consideration of green or sustainable concepts in order to meet this goal. This includes the potential for transferring impacts to other media. For instance, many remedial decisions do not assess greenhouse gas (GHG) emissions, energy usage, or community engagement factors prior to the investigation or remedy implementation. Considering these factors throughout the investigation and remedy implementation process may lessen negative effects of the overall cleanup impact while the remediation remains protective of human health and the environment. The consideration of these factors is Green and Sustainable Remediation (GSR) - the site-specific employment of products, processes, technologies, and procedures that mitigate contaminant risk to receptors while making decisions that are cognizant of balancing community goals, economic impacts, and net environmental effects. Many state and federal agencies are just beginning to assess and apply green and sustainable remediation into their regulatory programs. This training provides background on GSR concepts, a scalable and flexible framework and metrics, tools and resources to conduct GSR evaluations on remedial projects. The training is based on the ITRC's Technical & Regulatory Guidance Document: Green and Sustainable Remediation: A Practical Framework (GSR-2, 2011) as well as ITRC's Overview Document, Green and Sustainable Remediation: State of the Science and Practice (GSR-1, 2011). Beyond basic GSR principles and definitions, participants will learn the potential benefits of incorporating GSR into their projects; when and how to incorporate GSR within a project's life cycle; and how to perform a GSR evaluation using appropriate tools. In addition, a variety of case studies will demonstrate the application of GSR and the results. The training course provides an important primer for both organizations initiating GSR programs as well as those organizations seeking to incorporate GSR considerations into existing regulatory guidance.

Slides for "NARPM Presents...Redux of NARPM 2011 Greener Cleanups Sessions: Greener Cleanups Case Studies," Apr 23, 2012

jodi.mccarty@tetratech.com (Jodi McCarty) — Mon, 23 Apr 2012 23:00:00 GMT

In May 2011, EPA held its annual National Association of Remedial Project Managers (NARPM) training program in Kansas City, MO, and for the fourth year in a row, one of our most attended sessions was on Greener Cleanups (GC). And like last year, we are offering those talks again to an online audience! EPA's definition of GC includes the practice of considering the environmental effects of a remediation strategy (i.e., the remedy selected and the implementation approach) early in the process, and incorporating options to maximize the net environmental benefit of the cleanup action. Back in August, we offered the first of three webinar sessions on the Footprint Methodology, and this April we will showcase the remaining two webinars. We've got more case studies and maturing policy and guidance that we'd like to share with an online audience. EPA's Technical Support Project, led by the Engineering Forum, will present these on April 17th and 23rd, both from 1:00 p.m. to 3:00 p.m. Eastern. Each 2 hour session will include policy and/or case studies, with time for Q&A along the way. During this seminar, personnel from EPA Region 4 will present a case study on the Savannah River Site in Aiken, South Carolina. In addition, a case study from EPA Region 9 on the Apache Powder Site in Arizona and from EPA Region 10, the Well 12A site in Tacoma, Washington, will also be presented.

jodi.mccarty@tetratech.com (Jodi McCarty) — Thu, 19 Apr 2012 23:00:00 GMT

This 2-hour webinar, led by two EPA Region IV Remedial Project Managers with the Superfund Division, Superfund Remedial Branch, and a Research Hydrologist with the U.S. Geological Survey, will provide an overview of the various science-based approaches used from 2008-2012 at the Capital City Plume (CCP) Superfund Site characterized by chlorinated-solvent and metals-contaminated groundwater. The webinar will cover t9e investigation of: (1) potential contaminant source areas, (2) contamination pathways, and (3) probable contaminant release histories. The same science-based approaches successfully used at the CCP Site also can be used at other similar Superfund sites where potentially responsible party assessment is not straightforward.

pachon.carlos@epa.gov (Carlos Pachon) — Wed, 18 Apr 2012 23:00:00 GMT

The process of cleaning up a hazardous waste site uses energy, water, and other natural or materials resources and consequently creates an environmental footprint of its own. The US EPA recently released a methodology for quantifying the environmental footprints. The information obtained helps prioritize efforts to reduce the footprint and improve the outcome of cleanups under any regulatory program. The two-hour seminar will: (1) discuss the genesis of the effort; (2) summarize the methodology for estimating or quantifying the footprint and the associated metrics; and (3) provide an interactive case study to allow participants to get a feel for the process of calculating an environmental footprint and evaluating options to reduce it. An open forum will be held after the presentations, during which participants will be able to submit questions and feedback to the speakers.

Slides for "Permeable Reactive Barrier: Technology Update," Apr 10, 2012

training@itrcweb.org (the ITRC Training Program) — Tue, 10 Apr 2012 23:00:00 GMT

A Permeable Reactive Barrier (PRB) is an in situ permeable treatment zone designed to intercept and remediate a contaminant plume to remediate groundwater. The treatment zone may be created directly using reactive materials such as iron, or indirectly using materials designed to stimulate secondary processes (e.g., adding carbon substrate and nutrients to enhance microbial activity). Since its first implementation in the early 1990s, over 200 PRB systems have been installed to treat groundwater contaminants and PRBs have become an important component among the various technologies available to remediate groundwater contamination. The ITRC Technical/Regulatory Guidance Permeable Reactive Barrier: Technology Update (PRB-5, 2011) and associated Internet-based training is intended to help guide state and federal regulators, consultants, project managers, and other stakeholders and technology implementers through the decision process when a PRB is being considered as a remedy, or part of a remedy, to address contaminated groundwater; and to provide updated information regarding several technical aspects of the PRB using information attained from the more than 15 years that the PRB has been a viable and accepted in situ remediation technology for contaminated groundwater. The guidance and training provides an update on PRBs to include discussions of additional types of reactive media and contaminants that can be treated, design considerations, construction/installation approaches and technologies, performance assessment, and longevity. If you are unfamiliar with PRBs, we ask that you review background information on PRBs prior to attending the training class. Documents produced by the ITRC PRB team are available for review on the ITRC Permeable Reactive Barriers Guidance Documents page. You can access archives of previous ITRC trainings at http://www.clu-in.org/conf/itrc/advprb_032102/, http://www.clu-in.org/conf/itrc/prb_031902/, and http://www.clu-in.org/conf/itrc/prbll_061506/.

Slides for "Integrated DNAPL Site Strategy," Apr 5, 2012

training@itrcweb.org (the ITRC Training Program) — Thu, 5 Apr 2012 23:00:00 GMT

Sites contaminated by chlorinated solvents present a daunting environmental challenge, especially at sites with dense nonaqueous phase liquid (DNAPL) still present. Restoring sites contaminated by chlorinated solvents to typical regulatory criteria (low parts-per-billion concentrations) within a generation (~20 years) has proven exceptionally difficult, although there have been successes. Site managers must recognize that complete restoration of many of these sites will require prolonged treatment and involve several remediation technologies. To make as much progress as possible requires a thorough understanding of the site, clear descriptions of achievable objectives, and use of more than one remedial technology. Making efficient progress will require an adaptive management approach, and may also require transitioning from one remedy to another as the optimum range of a technique is surpassed. Targeted monitoring should be used and re-evaluation should be done periodically. This 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 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 This IDSS guidance and training is intended for regulators, remedial project managers, and remediation engineers responsible for sites contaminated by chlorinated solvents. Because the subject matter is complex, this guidance assumes a functional understanding of the field and is targeted towards experienced users; however, novices will benefit through descriptions and references of the latest evolution of site characterization challenges; realistic planning of site restoration; evolving treatment techniques; and evaluating, monitoring and interpreting mass transport in the subsurface aqueous and vapor phases. While the primary focus of the document is on DNAPL sites, other types of contaminated sites (e.g. petroleum, mixed contaminants, etc.) can use the same fundamental process described in this guidance. For reference during the training class, participants should have a copy of the flow diagram, Figure 1-2 on page 6 of the ITRC Technical and Regulatory Guidance document, ITRC Integrated Dense Nonaqueous Phase Liquid Site Strategy (IDSS-1, 2011) and available as a 1-page PDF at http://www.cluin.org/conf/itrc/IDSS/ITRC-IDSS-1-Figure1-2.pdf.

jodi.mccarty@tetratech.com (Jodi McCarty) — Wed, 4 Apr 2012 23:00:00 GMT

Come hear the latest on Institutional Controls (IC) during this webinar. Assuming you know the basics about ICs: (1) they are non-engineered components of a remedy, including legal and communication mechanisms to protect the remedy, and (2) most Superfund sites require effective ICs to ensure that remedies remain protective. However, as always, the "devil is in the details." The planning and implementation of ICs has come a long way since the early days of Superfund, as we have had to create and innovate to make ICs work for unique situations. Also, new developments help us with our endeavor for effective ICs. The session will start with a discussion of the latest guidance: the "Planning, Implementing, Monitoring, and Enforcing of Institutional Controls" (PIME) Guidance. We will also briefly touch on the 2011 "Recommended Evaluation of Institutional Controls, Supplement to the Five-year Review Guidance" and other pending IC guidance. This is followed by case study examples involving local ordinances in Region 7, and complex IC issues in Region 5. Finally, a special topic of implementing ICs on Tribal Lands will be examined. All questions and issues related to ICs are welcome!

Slides for "Early-life Exposures - Long-term Health Consequences Part 3: PCE and Phthalates," Apr 2, 2012

cranej2@niehs.nih.gov (Justin Crane) — Mon, 2 Apr 2012 23:00:00 GMT

This series "Early-life Exposures - Long-term Health Consequences" features SRP research in revealing the vulnerability of a developing child by identifying how biological systems are disturbed in this early period of life. The series will showcase cutting edge research findings that illuminate the consequences of early life exposures to metals and organic contaminants of emerging concern. The third session of this series "Early-life Exposures - Long-term Health Consequences Part 3: PCE and Phthalates" features SRP grantees Dr. Ann Aschengrau (Boston University), Dr. John Meeker (University of Michigan) and Dr. Rita Loch-Caruso (University of Michigan) and their work with early exposures and their resulting developmental effects. Numerous neurotoxic effects have been associated with tetrachloroethylene (PCE) exposure in adults, but little is understood about long-term nervous system effects from early exposures. Dr. Aschengrau's retrospective epidemiological study on a population of adults investigates the association between prenatal and early childhood exposure to PCE-contaminated drinking water and a variety of neurotoxic effects including the occurrence of drug use and mental illness. Dr. Meeker employs molecular epidemiological methods to explore environmental, genetic, demographic, and behavioral factors associated with preterm birth in a cohort of pregnant women in Puerto Rico, a study from the Northeastern University SRP Center. Puerto Rico has a particularly alarming preterm birth rate and there is mounting evidence that environmental factors play a key role. This study targets phthalates as the primary exposure of interest, due to their increasingly widespread exposure in Puerto Rico and the US and their association with reduced gestational age and other effects potentially linked with preterm birth, including inflammation, endocrine disruption, and oxidative stress. Using the Puerto Rican exposure scenario as a model, Dr. Loch-Caruso's research aims to explain the mechanisms by which environmental pollutant exposures increase women's risk for preterm births and other adverse birth outcomes, by investigating the relationship between the toxicological effect of oxidative stress from environmental contaminants and the activation of pathways associated of parturition.

The second session "Early Life Exposures - Long-term Health Consequences: Session 2, Metals and Metal Mixtures" features SRP grantees Dr. Robert Wright (Harvard University) and Dr. Rebecca Fry (UNC-CH) and their work with early exposure to metals and the resulting developmental effects. To better understand the neurodevelopmental consequences of exposure to mixtures of lead, manganese, and arsenic, Dr. Wright is conducting three cohort studies of metals and neurodevelopment among populations of children in Bangladesh, Mexico and Oklahoma. The combined efforts of these studies investigate the effects of mixed metal exposures on child development, comparing different developmental windows of exposure from prenatal life to age two. Prenatal exposure to cadmium has been associated with poor birth outcomes including low birth weight. Dr. Fry's research aims to obtain a better understanding of the underlying biological mechanisms involved in this association. This study employs in vitro and in vivo approaches to investigate gene-environment interactions that influence cadmium-induced signaling of inflammatory response genes.

Mining produces millions of tons of waste each year. Contaminants from unreclaimed or unremediated areas have affected millions of acres of land and over 10,000 miles of stream. Historical mining practices and the absence of routine mined-land reclamation, remediation, and restoration have led to legacy sites with significant environmental and human health impacts. New mining operations continue to have severe waste issues that must be addressed during and after the actual mining operation. Conventional remedial solutions are often lengthy, expensive, and unacceptable to the regulated and regulatory communities, as well as to the public. ITRC's Mining Waste Team developed the ITRC Web-based Mine 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 Mine Waste Technology Selection site to identify appropriate technologies, address all impacted media, access case studies, and understand potential regulatory constraints.

Slides for "Project Risk Management for Site Remediation," Mar 8, 2012

training@itrcweb.org (the ITRC Training Program) — Thu, 8 Mar 2012 23:00:00 GMT

Remediation Risk Management (RRM) is a course of action through which all risks related to the remediation processes (site investigations, remedy selection, execution, and completion) are holistically addressed in order to maximize the certainty in the cleanup process to protect human health and the environment. Remediation decisions to achieve such a goal should be made based on threshold criteria on human health and ecological risks, while considering all the other potential project risks. Through this training course and associated ITRC Technical and Regulatory Guidance Document: Project Risk Management for Site Remediation (RRM-1, 2011), the ITRC RRM team presents tools and processes that can help the site remediation practitioner anticipate, plan for, and mitigate many of the most common obstacles to a successful site remediation project. Examples of project risks include remediation technology feasibility risks; remedy selection risks; remedy construction, operation and monitoring risks; remedy performance and operations risks; environmental impacts of systems during their operation; worker safety risk, human health and ecological impacts due to remedy operation; as well as costs and schedules risks including funding and contracting issues. You should learn: the principles and elements of Remediation Risk Management (RRM); the importance and benefits of RRM; how to implement RRM based on a discussion of case studies: how RRM can help you achieve more successful remediation; and how to use the ITRC RRM information to your benefit.

Slides for "Use and Measurement of Mass Flux and Mass Discharge," Feb 16, 2012

training@itrcweb.org (the ITRC Training Program) — Thu, 16 Feb 2012 23:00:00 GMT

Most decisions at groundwater contamination sites are driven by measurements of contaminant concentration -- snapshots of contaminant concentrations that may appear to be relatively stable or show notable changes over time. Decisions can be improved by considering mass flux and mass discharge. Mass flux and mass discharge quantify the source or plume strength at a given time and location resulting in better-informed management decisions regarding site prioritization or remedial design as well as lead to significant improvements in remediation efficiency and faster cleanup times. The use of mass flux and mass discharge is increasing and will accelerate as field methods improve and practitioners and regulators become familiar with its application, advantages, and limitations. The decision to collect and evaluate mass flux data is site-specific. It should consider the reliability of other available data, the uncertainty associated with mass flux measurements, the specific applications of the mass flux data, and the cost-benefit of collecting mass measurements. The ITRC technology overview, Use and Measurement of Mass Flux and Mass Discharge (MASSFLUX-1, 2010), and associated Internet-based training provide a description of the underlying concepts, potential applications, description of methods for measuring and calculating, and case studies of the uses of mass flux and mass discharge. This Technology Overview, and associated internet based training are intended to foster the appropriate understanding and application of mass flux and mass discharge estimates, and provide examples of use and analysis. The document and training assumes the participant has a general understanding of hydrogeology, the movement of chemicals in porous media, remediation technologies, and the overall remedial process. Practitioners, regulators, and others working on groundwater sites should attend this training course to learn more about various methods and potential use of mass flux and mass discharge information.

jones.shea@epa.gov (Shea Jones) — Tue, 7 Feb 2012 23:00:00 GMT

This webinar will give an overview of two draft decision trees that the Environmental Protection Agency (EPA) and National Renewable Energy Laboratory (NREL) created to screen potentially contaminated and underutilized sites for solar and wind potential. These decision trees were created to guide state and local governments and other stakeholders through a process for screening sites for their suitability for solar photovoltaic (PV) and wind energy. Targeted sites include underutilized "greyfields", commercial/industrial rooftops, brownfields, Superfund sites, RCRA sites, publicly owned facilities, abandoned parcels, and landfills. EPA encourages the development of these targeted sites, instead of green space. Through the RE-Powering America's Land Initiative, the EPA encourages renewable energy development on potentially contaminated land. The EPA also promotes redevelopment of urban sites to achieve "Smart Growth" objectives. Community vision for the site, as well as the site's key attributes, should shape the redevelopment plan. These decision trees can be used to screen individual sites for solar or wind potential or for a community-scale evaluation of candidate sites. They are not intended to replace or substitute the need for a detailed site-specific assessment that would follow an initial screening based on criteria contained in the trees. Tips on how users can obtain information relevant to various parameters in the trees are provided. These draft tools have been posted on EPA's RE-Powering America's Land website at http://www.epa.gov/renewableenergyland/develop_potential_fs.htm. EPA is seeking your feedback on these draft decision trees. Please send comments by February 16 to Shea Jones at jones.shea@epa.gov

Slides for "Early-life Exposures - Long-term Health Consequences: Part 1 Brominated Flame Retardants," Feb 3, 2012

cranej2@niehs.nih.gov (Justin Crane) — Fri, 3 Feb 2012 23:00:00 GMT

This series "Early-life Exposures — Long-term Health Consequences" features SRP research in revealing the vulnerability of a developing child by identifying how biological systems are disturbed in this early period of life. The series will showcase cutting edge research findings that illuminate the consequences of early life exposures to metals and organic contaminants of emerging concern. The first session "Early-life Exposures - Long-term Health Consequences: Part 1 Brominated Flame Retardants" features Dr. Linda Birnbaum (Director, National Institute of Environmental Health Sciences), Dr. Heather Stapleton (Duke University) and Dr. Prasada Kodavanti (US EPA). The seminar will feature work with brominated flame retardants, compounds that are frequently added to consumer products (such as furniture and electronics) to improve fire safety. Polybrominated flame retardants (PBDEs) can cross the placental barrier from mother to fetus and influence childhood development years later. PBDEs have been associated with alterations in thyroid hormone levels, reduced fertility, and neurodevelopmental deficits. Dr. Stapleton will present a recent study exploring the association between PBDEs exposure measured in serum levels and thyroid hormone levels among a cohort of pregnant women. Additionally, she will highlight new research insights into possible mechanisms of thyroid hormone dysregulation. Dr. Kodavanti will discuss a study evaluating the neurobehavioral, hormonal, and reproductive effects of perinatal exposure to a commercial PBDE mixture, DE-71, in a population of rats. PBDE was demonstrated to cross the blood-placenta and blood-brain barriers, resulting in subtle changes in some parameters of neurobehavior, dramatic changes in thyroid hormone levels, and alterations in both male and female reproductive endpoints. The seminar will be moderated by Dr. William A. Suk, Director of the Superfund Research Program at NIEHS.

Slides for "Innovative Technologies Used to Quantify Environmental Contaminant Bioavailability and Characterize Environmental Exposure," Jan 30, 2012

cranej2@niehs.nih.gov (Justin Crane) — Mon, 30 Jan 2012 23:00:00 GMT

Accurately determining a person's exposures to environmental chemicals is a central challenge to evaluating potential health consequences of contaminants. Quantifying environmental contaminant bioavailability is one fundamental nexus for characterizing environmental exposure. Single-time collection grab samples generates an impossible number of complex samples to analyze analytically that are also too dilute to reasonable assess biological activity. Analysis of trapped local aquatic organisms such as fish or shellfish can be used to assess persistent bioaccumulative toxicants, but suffer from many limitations: metabolism, difficulties in obtaining samples, necessary destructive sampling and inherent biological and physiological variability, nor does one know how long the organism was exposed to the toxicants. Many similar challenges exist with the analysis of biomarkers in epidemiological studies of environment and disease. To overcome these issues, we have further developed passive sampling devices (PSDs) for water, air, sediment and personal monitoring now used at multiple Superfund sites, in the Gulf of Mexico as part of the DeepWater Horizon oil spill, and in several western Africa countries as part of an on-going United Nations sponsored pesticide-monitoring project. Membranes in PSDs sequester thousands of bioavailable chemicals including previously unmonitored chemicals. The micro-porous and hydrophobic nature of the membranes was chosen to mimic both chemical and physical selective processes that affect uptake by organisms. We now seamlessly and routinely use the PSD extracts from water exposures in the embryonic zebrafish and Ames assay models. Because contaminants sequestered by such membranes are recovered for use in analytical and bioassays, we are able to combine continuous sampling with biological endpoints that will enhance our ability to assess effectiveness and mitigation of toxicity. The design, calibration, use and comparison of PSD membrane technologies will be discussed. Two applications of the PSD will be presented; the first will illustrate the broad utility of the PSD technique including lower analytical cost while also providing a seamless, no additional preparation, extract that can bridge relevant environmental exposure to biological response assays. A brief comparisons with other types of PSD technologies will be presented, including an analytical comparison with SPMDs were we demonstrate an 80% reduction in solvent use, elimination of chlorinated solvents, without a reduction in effectiveness or analytical sensitivity as an example. Finally, results from bridging relevant environmental exposures with two model biological systems, the embryonic zebrafish and Ames models, as a seamless and integrated bio-analytical tool will be presented. Temporal increases of PAHs during active remediation will be discussed. In the second application, PSDs were deployed in water and air at near shore locations in the Gulf of Mexico prior to and during shoreline oiling from the Deepwater Horizon oil spill. Detection limits for individual polycyclic aromatic hydrocarbons ranged from 0.001 to 0.05 ng/L and are typical of the technology. Deployments typically ranged from four to 30 days although other deployment times may be employed. Furthermore, PSD extracts are compatible with both LC and GC screening methods such as the DRS 1,200 chemicals GCMS method. The application of PSD as a surrogate for biota will be presented.

Audio for "Incorporating Bioavailability Considerations into the Evaluation of Contaminated Sediment Sites," Jan 26, 2012 (Part 1 of 2)

training@itrcweb.org (the ITRC Training Program) — Thu, 26 Jan 2012 23:00:00 GMT

The U.S. Environmental Protection Agency estimates that approximately 10 percent (over a billion cubic yards) of the sediment underlying our nation's surface water is sufficiently contaminated with pollutants to pose potential risks to fish and to humans and wildlife that eat fish. Based on current average costs for managing contaminated sediments, this volume of material could cost several trillion dollars to dredge. Methods to assess the potential effect of sediment contamination on human or ecological health are historically based on total contaminant concentrations in the bulk sediment. However, research conducted over the past fifteen years has shown that the bioavailability of many of these contaminants to receptors is much less than the total amount of contaminant in the sediment. "Bioavailability processes," as defined by the National Research Council, are the "individual physical, chemical, and biological interactions that determine the exposure of plants and animals to chemicals associated with soils and sediments." Only the bioavailable fraction of an environmental contaminant may be taken up and subsequently result in an effect on an organism. Incorporating bioavailability considerations in the calculation of risk can optimize the extent of cleanup required to be protective, improve site decision-making, and can be an important factor in balancing the risks caused by remedial action with the risks addressed by remedial action. ITRC's web-based Technical and Regulatory Guidance, Incorporating Bioavailability Considerations into the Evaluation of Contaminated Sediment Sites (CS-1, 2011) and associated Internet-based training are intended to assist state regulators and practitioners with understanding and incorporating fundamental concepts of bioavailability in contaminated sediment management practices. This guidance and training describe how bioavailability considerations can be used to evaluate exposure at contaminated sediment sites, the mechanisms affecting contaminant bioavailability, available tools used to assess bioavailability, the proper application of those tools, and how bioavailability information can be incorporated into risk-management decisions. This guidance and training also contain summaries of case studies where bioavailability has been assessed and considered in the contaminated sediment remedial decision making process. This guidance and training provide insight on how bioavailability assessments can be used to understand, mitigate, and manage risk at a contaminated sediment site, often at a reduced overall project cost. The intended users of this guidance and training participants are individuals who have a working knowledge of contaminated sediment management but seek additional information about bioavailability. Prior to the training class, participants are encouraged to review the following documents: ITRC's web-based Technical and Regulatory Guidance, Incorporating Bioavailability Considerations into the Evaluation of Contaminated Sediment Sites (CS-1, 2011) http://www.itrcweb.org/contseds-bioavailability U.S. Environmental Protection Agency, "Ecological Risk Assessment Guidance for Superfund: Process for Designing and Conducting Ecological Risk Assessment"- Interim Final, June 1997 http://www.epa.gov/oswer/riskassessment/ecorisk/ecorisk.htm U.S. Environmental Protection Agency, "Risk Assessment Guidance for Superfund (RAGS)" Volume 1 -- Human Health Evaluation Manual, Supplement to Part A: Community Involvement in Superfund Risk Assessments, 1989 http://www.epa.gov/oswer/riskassessment/ragsa/ci-ra.htm To view the slides associated with this audio, please visit http://www.clu-in.org/conf/itrc/ConSeds_012612/

With green space lands at a premium and communities looking for options to meet their recreational needs, some cleaned up Superfund sites are presenting a unique opportunity for development of soccer fields. EPA's Superfund Redevelopment Initiative (SRI), the U.S. Soccer Foundation and communities are working at Superfund sites to turn this opportunity into a reality. This webinar will share the stories of several Superfund sites from around the country that have been successfully redeveloped into soccer fields and how this transformation was accomplished. The U.S. Soccer Foundation, which has supported the reuse of Superfund sites as soccer fields across the Country, will share information on the webinar about resources available to communities looking to develop soccer fields. EPA will conclude the webinar by sharing tools and resources available to communities to think about future use of sites, including use as soccer fields, in the context of cleanup and long-term safety.

Solidification/Stabilization (S/S) is a remedial technology option which blends treatment reagents into contaminated material to impart physical and/or chemical changes to reduce the flux of contamination that leaches from a contaminant source to within acceptable parameters set forth in a site-specific remediation goal. S/S can be effective for metals, asbestos, radioactive materials, oxidizers, PAHs, PCBs, and pesticides and is potentially effective for dioxins/furans, some VOCs and other organics. Although there is abundant literature describing the S/S process and test methods for design and implementation, there was a lack of guidance for assessing performance. 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 reference during the training class, participants should have available a copy of the process diagram, Figure 4-1 on page 29 of the ITRC Technology and Regulatory Guidance Document Development of Performance Specifications for Solidification/Stabilization (S/S-1, 2011) and available as a 1-page PDF at http://www.cluin.org/conf/itrc/ss/ITRC-SS-Process.pdf.

Slides for "Mine Tailings: Enumeration and Remediation," Jan 11, 2012

cranej2@niehs.nih.gov (Justin Crane) — Wed, 11 Jan 2012 23:00:00 GMT

This seminar will feature Dr. Eric Betterton and Dr. Raina Maier from the University of Arizona Superfund Research Program and will focus on field trials being performed at mining sites in Arizona. Mine tailings are large piles of crushed rock leftover after the minerals of interest have been processed. They often do not support establishment of a plant cover, are prone to wind and water erosion, and may contribute to the dispersion of associated metal toxicants. Dr. Eric Betterton will discuss size-selective characterization of aerosols collected with samplers called "Multiple Orifice Uniform Deposit Impactors" at two Arizona mining sites, the Asarco plant in Hayden, AZ, and the Iron King Mine and Humboldt Smelter Superfund site in Dewey-Humboldt, AZ. Chemical speciation shows that arsenic and lead occur preferentially in the submicron fraction at both sites; lead isotope analysis shows great promise for source apportionment at both sites; and scanning electron microcopy shows evidence for spherical particle formation by high-temperature processing at Hayden. Data from dust flux towers installed at Iron King, and dust modeling studies will be described. Dr. Raina Maier will discuss phytostabilization, a technology being investigated for remediation of mine tailings sites in arid and semi-arid environments. The goal is to create a vegetative cap using native plants that will 1) prevent wind and water erosion of the tailings, 2) stabilize metal contaminants in the rooting zone, and 3) avoid shoot uptake of metal contaminants. The Iron King Mine and Humboldt Smelter Superfund Site is adjacent to the town of Dewey-Humboldt, Arizona. Soil in residential yards contains elevated levels of arsenic, lead, and zinc associated with tailings particles that have been dispersed as dust, primarily by wind. Working together with the site owner and Region 9 EPA, a phytostabilization trial was initiated on site in May 2010, which was further expanded in 2011, using native plants that were shown to meet successful phytostabilization criteria in preliminary greenhouse trials. The site is being monitored to determine whether greenhouse results can be successfully translated to the field and to examine changes in chemical, physical, and biological properties of the tailings as phytostabilization occurs.

Slides for "LNAPL Characterization and Recoverability - Improved Analysis - Part 2," Dec 13, 2011

training@itrcweb.org (the ITRC Training Program) — Tue, 13 Dec 2011 23:00:00 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 GoalsPart 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. 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).

Slides for "Biofuels: Release Prevention, Environmental Behavior, and Remediation," Dec 6, 2011

training@itrcweb.org (the ITRC Training Program) — Tue, 6 Dec 2011 23:00:00 GMT

Biofuels and biofuel blends are a new category of transportation fuels and are defined as liquid fuels and blending components produced from renewable biomass feedstocks used as alternative or supplemental fuels for internal combustion engines. Their manufacture and consumption are increasing, in part, due to usage mandates and incentives both in the United States and abroad. This expanded use of biofuel and biofuel blends increases the potential frequency of releases due to increased manufacture, transportation, storage, and distribution. Because biofuels differ from conventional fuels with respect to their physical, chemical, and biological properties, their introduction poses challenges with respect to understanding the potential impacts of releases to the environment. Specifically, once released into the environment, these fuels will exhibit different environmental behaviors as compared to conventional fuels. This training, which is based on the ITRC's Biofuels: Release Prevention, Environmental Behavior, and Remediation (Biofuels-1, 2011), focuses on the differences between biofuels and conventional fuels specific to release scenarios, environmental impacts, characterization, and remediation. The trainers will define the scope of the potential environmental challenges by introducing biofuel fundamentals, regulatory status, and future usage projections. Participants will learn how and when to use the ITRC biofuels guidance document for their projects. They will understand the differences in biofuel and petroleum behavior; become familiar with the biofuel supply chain, potential release scenarios and release prevention; be able to develop an appropriate conceptual model for the investigation and remediation of biofuels; and select appropriate investigation and remediation strategies.
