Audio for "FRTR Presents: Large-Dilute Plumes: Challenges and Opportunities," May 1, 2013

kenda.neil@navy.mil (Kenda Neil) — Wed, 1 May 2013 23:00:00 GMT

Recently, "large-dilute plumes" of chlorinated solvents have emerged as a peculiar challenge in environmental clean-up. This class of plume has several defining characteristics. These characteristics include biogeochemical conditions that result in slow contaminant degradation and that allow plume expansion, as well as matrix diffusion that results in secondary sources and that extends remediation timeframe. Research at these sites has highlighted key challenges and potential opportunities. Complicated fine-scale heterogeneity resulting from the interaction of migrating contaminants with subsurface lithology and hydrology is a particularly significant and recurring challenge — resulting in concentrated plume cores and the need for innovative-focused characterization and monitoring. Understanding the subsurface distribution of contaminants and how the plume is changing in time and space are keys to successful environmental response actions. Research and data on attenuation of contaminants resulting from physical assimilation along the flow path (such as a plume interacting with inactive pore spaces) and from degradation by abiotic and microbial processes have extended our knowledge of natural attenuation rates in aerobic-oligotrophic aquifers. The research indicates that aerobic processes, particularly abiotic degradation due to magnetite/minerals and aerobic cometabolism, are occurring in many large-dilute plumes. The attenuation rates are correlated with measurable parameters such as magnetic susceptibility or various microbial population metrics, including oxygenase enzyme activity probes, DNA composition/quantity, and total microbial counts. Consistent with the observed plume scales, the data confirm that aerobic degradation processes are slower than anaerobic degradation processes. Nonetheless, incorporation of these natural rates into models and predictions provides an important tool to aid in developing a comprehensive strategy for large-dilute plumes — mitigating the requirement for complete removal during source treatment and encouraging combined remedies as well as the development of amendments to sustainably and cost-effectively enhance degradation rates.

Slides for "Green & Sustainable Remediation," Apr 23, 2013

training@itrcweb.org (the ITRC Training Program) — Tue, 23 Apr 2013 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 "Incorporating Bioavailability Considerations into the Evaluation of Contaminated Sediment Sites," Apr 18, 2013

training@itrcweb.org (the ITRC Training Program) — Thu, 18 Apr 2013 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

Slides for "Project Risk Management for Site Remediation," Apr 16, 2013

training@itrcweb.org (the ITRC Training Program) — Tue, 16 Apr 2013 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.

Audio for "Biofuels: Release Prevention, Environmental Behavior, and Remediation," Mar 12, 2013 (Part 1 of 2)

training@itrcweb.org (the ITRC Training Program) — Tue, 12 Mar 2013 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.

Slides for "LNAPL Characterization and Recoverability - Improved Analysis - Part 2," Mar 7, 2013

training@itrcweb.org (the ITRC Training Program) — Thu, 7 Mar 2013 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).

training@itrcweb.org (the ITRC Training Program) — Thu, 14 Feb 2013 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.

crspier@gmail.com (Candace Spier) — Wed, 6 Feb 2013 23:00:00 GMT

In this webinar, we will hear from San Francisco physician Dr. Jane Hightower, who has been extremely instrumental in bringing national attention to how mercury affects our health. More than 10 years ago, Dr. Hightower began recognizing low-level mercury poisoning in patients who regularly ate certain kinds of fish. She delved deeper into the issues of competing interests, varying government standards, and looked at what it would take get mercury poisoning seen as a problem. She has lectured on this topic extensively across the country, her articles have appeared in several scientific and medical journals including Environmental Health Perspectives and San Francisco Medicine, and has written a book Diagnosis: Mercury: Money, Politics and Poison. Today, Dr. Hightower will lead a discussion about mercury exposure and human health - a view from the trenches. She will present a 30 minute talk to be followed by 30 minutes for Q&A and comments from the participants. Please join us for a very informative and engaging discussion.

mahoney.michele@epa.gov (Michele Mahoney) — Wed, 6 Feb 2013 23:00:00 GMT

Passive Treatment 101: An Overview of the Technologies Presenter: Jim Gusek, (Golder Associates Inc.) There are basically three kinds of passive treatment technologies for treating mining influenced water (MIW): Abiotic, Limestone-based methods for treating net-acidic MIW have been effective in adding alkalinity; Semi-biological methods that condition MIW for subsequent limestone dissolution; and Biologically-facilitated components to round out the list. Some of the biological components can function without plants: Biochemical Reactors (BCRs) are typically applicable to metal mine drainage with high acidity and a wide range of metals. In contrast, Aerobic Cells containing cattails and other plants are typically applicable to coal geology derived MIW where iron and manganese and mild acidity are problematic. Most passive treatment systems employ one or more of these cell types. The track record of aerobic cells and limestone-based methods in treating coal geology MIW is impressive, especially back in the eastern coalfields of the U.S. BCRs have tremendous potential in metal mining and coal mining geological environments but have not seen as wide an application. Aerobic manganese removal cells are also amenable to sequestering heavy metals as long as iron (if present) is removed first and the MIW is circum-neutral. This presentation compares the advantages and disadvantages the various passive treatment components and is an introduction to the wide range of remediation design options available to practitioners of passive treatment. Rather than propose “cookbook” designs, the presentation details a recommended staged-approach of laboratory-, bench-, and pilot-scale testing which has been shown to increase the likelihood of a successful design, especially for MIW with complex chemistry. Watershed Restoration Through the Implementation of Passive Treatment Technology in the Lambert Run Watershed, Harrison County, West Virginia Presenter: J. Brady Gutta, (West Virginia Water Research Institute) The presentation will provide a brief history of the Lambert Run Watershed, and discuss the implementation of five passive treatment installations and their impact on water quality. A general overview of acid mine drainage (AMD) chemistry will also be provided. MIW treatment at the Leviathan Mine Superfund Site, California Presenter: Kevin Mayer, (U.S. EPA) Leviathan Mine is a 250-acre abandoned open-pit sulfur mine 7000 feet high on the eastern slope of the Sierra Nevada mountain range near Lake Tahoe in California. Major environmental problems originated from open-pit sulfur mining active from 1951 through 1962. The resulting high sulfur content in the waste rocks and fractures at the mine site have been turning snowmelt, rain and groundwater into sulfuric acid, which leaches contaminants from the native minerals such as arsenic, copper, nickel, zinc, chromium along with aluminum and iron. Acid discharges from the mine severely impacted a nine-mile mountain watershed flowing into the Carson River in Nevada. Prior to recent treatment activities, a thick layer of orange precipitate coated the streambed most of the year until it washed into the East Fork of the Carson River with the high spring runoff. The presentation is a case study focusing on the three different treatment systems currently operating at the site, including lime neutralization and full-scale biological treatment systems, with significant improvement in stream water quality.

Slides for "Mining Waste Treatment Technology Selection," Jan 15, 2013

training@itrcweb.org (the ITRC Training Program) — Tue, 15 Jan 2013 23:00:00 GMT

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 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.

training@itrcweb.org (the ITRC Training Program) — Thu, 10 Jan 2013 23:00:00 GMT

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.

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.
