Substrate Longevity and Long-Term Performance of Biochemical Reactors for Passive Treatment of Mine-Impacted Water

The Society of American Military Engineers (SAME) Denver Post and Philadelphia Post along with the US Environmental Protection Agency (EPA) are hosting a series of webinars based on talks given at recent Design and Construction Issues at Hazardous Waste Sites (DCHWS) Symposiums. The mission of the DCHWS symposiums is to facilitate an interactive engagement between professionals from government and the private sector related to relevant and topical issues affecting applications of engineering and science associated with cleaning up hazardous waste sites. The symposiums also serve as a platform to facilitate the exchange of information, encourage dialogue, share experiences, and build and enhance communication among design and construction professionals.

Biochemical reactors (BCR) have become an important treatment unit within passive treatment systems (PTS) designed for mine impacted water; however, operational longevity has remained a persistent concern. This presentation will present an overview on the background, history and principles on the use of BCRs to treat mine-impacted water. This will include a detailed review of the configuration, operation and performance of a typical BCR system and will provide data and observations from two long-term (>8 years) operating BCR systems as examples. This presentation will demonstrate that BCRs are an effective low cost, long term, and sustainable option for meeting water quality targets of mine impacted waters. This presentation will be a continuum of the two presentations previously presented (2018, 2019) in the DCHWS West forums. Both of the previous presentations focused on design, construction, and operation, while this presentation will focus on operation and maintenance, long-term performance, and overall system operational lifespan.

Considerations for Bulkheading Draining Mine Tunnels

Historically, underground hard rock mines are abandoned after the ore is mined out. Water then seeps into the fractures, mined out veins, and other mine workings where it combines with oxidized minerals to form sulfuric acid which then brings heavy metals into solution which then flows out as acid mine drainage (AMD). The AMD impacts the surrounding streams by providing a steady influx of acidic metal rich water, as well as surges of AMD from the collapse of underground dams where AMD has pooled. Such surges and sometimes all flows can be controlled by installing concrete plugs (bulkheads) in strategic locations. This webinar will address underground bulkheads in general and will present specific examples from Region 8 of bulkhead installations and water quality changes, including those at Dinero Tunnel, Pennsylvania Mines, and Captain Jack Mill sites.

Seminars Sponsored by the Interstate Technology and Regulatory Council


Characterization and Remediation of Fractured Rock

Interstate Technology Regulatory Council Characterization and remediation of contaminated groundwater in fractured rock has not been conducted or studied as broadly as groundwater at unconsolidated porous media sites. This unfamiliarity and lack of experience can make fractured rock sites perplexing. This situation is especially true in portions of the U.S. where bedrock aquifers are a primary source of drinking and process water, and demands on water are increasing. As a result, remedial activities often default to containment of contaminant plumes, point of use treatment and long-term monitoring rather than active reduction of risk. However, this attitude does not incorporate recent advances in the science and technology of fractured rock site characterization and remediation.
The basis for this training course is the ITRC guidance: Characterization and Remediation of Fractured Rock. The purpose of this guidance is to dispel the belief that fractured rock sites are too complex to characterize and remediate. The physical, chemical and contaminant transport concepts in fractured rock have similarities to unconsolidated porous media, yet there are important differences. These differences are the focus of this guidance.

By participating in this training class, you should learn to:
  • Use ITRC's Fractured Rock Document to guide your decision making so you can:
  • Develop quality Conceptual Site Models (CSMs) for fractured rock sites
  • Set realistic remedial objectives
  • Select the best remedial options
  • Monitor remedial progress and assess results
  • Value an interdisciplinary site team approach to bring collective expertise to improve decision making and to have confidence when going beyond containment and monitoring - - to actually remediating fractured rock sites.
Case studies of successful fractured rock remediation are presented to provide examples of how fractured rock sites can be evaluated and available tools applied to characterization and remediation.
Training participants are encouraged to view the associated ITRC guidance, Characterization and Remediation of Fractured Rock prior to attending the class.

Geospatial Analysis for Optimization at Environmental Sites

Interstate Technology Regulatory Council Optimization activities can improve performance, increase monitoring efficiency, and support contaminated site decisions. Project managers can use geospatial analysis for evaluation of optimization opportunities. Unlike traditional statistical analysis, geospatial methods incorporate the spatial and temporal dependence between nearby data points, which is an important feature of almost all data collected as part of an environmental investigation. The results of geospatial analyses add additional lines of evidence to decision making in optimization opportunities in environmental sites across all project life cycle stages (release detection, site characterization, remediation, monitoring and closure) in soil, groundwater or sediment remediation projects for different sizes and types of sites.

The purpose of ITRC's Geospatial Analysis for Optimization at Environmental Sites (GRO-1) guidance document and this associated training is to explain, educate, and train state regulators and other practitioners in understanding and using geospatial analyses to evaluate optimization opportunities at environmental sites. With the ITRC GRO-1 web-based guidance document and this associated training class, project managers will be able to:
  • Evaluate available data and site needs to determine if geospatial analyses are appropriate for a given site
  • For a project and specific lifecycle stage, identify optimization questions where geospatial methods can contribute to better decision making
  • For a project and optimization question(s), select appropriate geospatial method(s) and software using the geospatial analysis work flow, tables and flow charts in the guidance document
  • With geospatial analyses results (note: some geospatial analyses may be performed by the project manager, but many geospatial analyses will be performed by technical experts), explain what the results mean and appropriately apply in decision making
  • Use the project manager's tool box, interactive flow charts for choosing geospatial methods and review checklist to use geospatial analyses confidently in decision making

Long-term Contaminant Management Using Institutional Controls

Interstate Technology Regulatory Council Institutional controls (ICs) are administrative or legal restrictions that provide protection from exposure to contaminants on a site. When ICs are jeopardized or fail, direct exposure to human health and the environment can occur. While a variety of guidance and research to date has focused on the implementation of ICs, ITRC's Long-term Contaminant Management Using Institutional Controls (IC-1, 2016) guidance and this associated training class focuses on post-implementation IC management, including monitoring, evaluation, stakeholder communications, enforcement, and termination. The ITRC guidance and training will assist those who are responsible for the management and stewardship of Ics. ITRC has developed a downloadable tool that steps users through the process of planning and designing IC management needs. This tool can help to create a long lasting record of the site that includes the regulatory authority, details of the IC, the responsibilities of all parties, a schedule for monitoring the performance of the IC, and more. The tool generates an editable Long Term Stewardship (LTS) plan in Microsoft Word.

After attending the training, participants will be able to:
  • Describe best practices and evolving trends for IC management at individual sites and across state agency programs
  • Use this guidance to
    • Improve IC reliability and prevent IC failures
    • Improve existing, or develop new, IC Management programs
    • Identify the pros and cons about differing IC management approaches
  • Use the tools to establish an LTS plan for specific sites
  • Use the elements in the tools to understand the information that should populate an IC registry or data management system.

The target audience for this guidance includes environmental regulators at all levels of government, private and public responsible or obligated parties (Ops), current site owners and operators, environmental consultants, and prospective purchasers of property and their agents. Other stakeholders who have an interest in a property can also use this guidance to help understand how to manage Ics.

Connecting the Science to Managing LNAPL Sites a 3 Part Series - Part 3

Interstate Technology Regulatory Council Connecting the Science to Managing LNAPL Sites - 3-Part Series

The newly updated LNAPLs (Light Non-Aqueous Phase Liquids) 3-part training course series is based on the ITRC guidance: LNAPL Site Management: LCSM Evolution, Decision Process, and Remedial Technologies (LNAPL-3, 2018) and focuses on connecting the science to managing LNAPL sites and helping you:
  • Build upon your Understanding of LNAPL Behavior in the Subsurface (Part 1)
  • Develop your LNAPL Conceptual Site Model and LNAPL Remedial Goals (Part 2)
  • Select/Implement LNAPL Technologies (Part 3)
After this training series, the expectation is that you will have the skills and understanding to use ITRC science-based resources to improve decision making at your LNAPL sites. For regulators and other government agency staff, this improved understanding can hopefully be incorporated into your own LNAPL programs.

It is recommended that participants have a general understanding of hydrogeology and some familiarity with petroleum contaminated sites. The courses will build on your existing LNAPL knowledge and outline the framework for making LNAPL remediation and management decisions. It is expected that participants will attend this 3-part training series in sequence.

LNAPL Training Part 1: Understanding LNAPL Behavior in the Subsurface
Part 1 teaches how LNAPLs behave in the subsurface and examines what controls their behavior. Part 1:
  • Explains what LNAPL data can tell you about the LNAPL and site conditions
  • Covers how that information is applied to the development of an LNAPL conceptual site model (LCSM) (Part 2) and LNAPL technology selection (Part 3)
Relevant and practical examples are used to illustrate key concepts.

LNAPL Training Part 2: LNAPL Conceptual Site Models and the LNAPL Decision Process
Part 2 teaches participants how to develop an LNAPL conceptual site model (LCSM) and the overall framework for making LNAPL remediation and management decisions. Part 2:
  • Discusses key LNAPL and site data
  • Explains when and why those data may be important
  • Covers how to effectively organize the data into an LCSM
Part 2 also discusses how to address LNAPL concerns by selecting appropriate goals and objectives, choosing applicable technologies, and assigning remedial performance metrics and endpoints.

LNAPL Training Part 3: Using LNAPL Science, the LCSM, and LNAPL Goals to Select an LNAPL Remedial Technology
Part 3 of the training teaches the importance of informed remedial technology selection and appropriate technology application. Part 3:
  • Discusses remedial technology groups
  • Introduces specific and new remedial technologies
  • Reviews the technology selection process, how technologies can be combined to accelerate cleanup, and how the LCSM informs selection
A case study and examples demonstrate the use of these tools for remedial technology selection, implementation, and demonstration of successful remediation.
Training participants are encouraged to view the associated ITRC guidance, LNAPL Site Management: LCSM Evolution, Decision Process, and Remedial Technologies (LNAPL-3, 2018), prior to attending the class.

Petroleum Vapor Intrusion: Fundamentals of Screening, Investigation, and Management

Interstate Technology Regulatory Council Chemical contaminants in soil and groundwater can volatilize into soil gas and migrate through unsaturated soils of the vadose zone. Vapor intrusion (VI) occurs when these vapors migrate upward into overlying buildings through cracks and gaps in the building floors, foundations, and utility conduits, and contaminate indoor air. If present at sufficiently high concentrations, these vapors may present a threat to the health and safety of building occupants. Petroleum vapor intrusion (PVI) is a subset of VI and is the process by which volatile petroleum hydrocarbons (PHCs) released as vapors from light nonaqueous phase liquids (LNAPL), petroleum-contaminated soils, or petroleum-contaminated groundwater migrate through the vadose zone and into overlying buildings. Fortunately, in the case of PHC vapors, this migration is often limited by microorganisms that are normally present in soil. The organisms consume these chemicals, reducing them to nontoxic end products through the process of biodegradation. The extent and rate to which this natural biodegradation process occurs is strongly influenced by the concentration of the vapor source, the distance the vapors must travel through soil from the source to potential receptors, and the presence of oxygen (O2) in the subsurface environment between the source and potential receptors.

The ITRC Technical and Regulatory Guidance Web-Based Document, Petroleum Vapor Intrusion: Fundamentals of Screening, Investigation, and Management (PVI-1, 2014) and this associated Internet-based training provides regulators and practitioners with consensus information based on empirical data and recent research to support PVI decision making under different regulatory frameworks. The PVI assessment strategy described in this guidance document enables confident decision making that protects human health for various types of petroleum sites and multiple PHC compounds. This guidance provides a comprehensive methodology for screening, investigating, and managing potential PVI sites and is intended to promote the efficient use of resources and increase confidence in decision making when evaluating the potential for vapor intrusion at petroleum-contaminated sites. By using the ITRC guidance document, the vapor intrusion pathway can be eliminated from further investigation at many sites where soil or groundwater is contaminated with petroleum hydrocarbons or where LNAPL is present.

After attending this ITRC Internet-based training, participants should be able to:
  • Determine when and how to use the ITRC PVI document at their sites
  • Describe the important role of biodegradation impacts on the PVI pathway (in contrast to chlorinated solvent contaminated sites)
  • Value a PVI conceptual site model (CSM) and list its key components
  • Apply the ITRC PVI 8 step decision process to screen sites for the PVI pathway and determine actions to take if a site does not initially screen out, (e.g., site investigation, modeling, and vapor control and site management)
  • Access fact sheets to support community engagement activities at each step in the process
For reference during the training class, participants should have a copy of the flowcharts, Figures 1-2, 3-2, and 4-1 from the ITRC Technical and Regulatory Guidance Web-Based Document, Petroleum Vapor Intrusion: Fundamentals of Screening, Investigation, and Management (PVI-1, 2014) and are available as a 3-page PDF at http://www.cluin.org/conf/itrc/PVI/ITRC-PVI-FlowCharts.pdf

Remediation Management of Complex Sites

Interstate Technology Regulatory Council At some sites, complex site-specific conditions make it difficult to fully remediate environmental contamination. Both technical and nontechnical challenges can impede remediation and may prevent a site from achieving federal- and state-mandated regulatory cleanup goals within a reasonable time frame. For example, technical challenges may include geologic, hydrogeologic, geochemical, and contaminant-related conditions as well as large-scale or surface conditions. In addition, nontechnical challenges may also play a role such as managing changes that occur over long time frames, overlapping regulatory and financial responsibilities between agencies, setting achievable site objectives, maintaining effective institutional controls, redevelopment and changes in land use, and funding considerations.
This training course and associated ITRC guidance: Remediation Management of Complex Sites (RMCS-1, 2017), provide a recommended holistic process for management of challenging sites, termed "adaptive site management." This process is a comprehensive, flexible, and iterative process that is well-suited for sites where there is significant uncertainty in remedy performance predictions. Adaptive site management includes the establishment of interim objectives and long-term site objectives that consider both technical and nontechnical challenges. Periodic adjustment of the remedial approach may involve multiple technologies at any one time and changes in technologies over time. Comprehensive planning and scheduled evaluations of remedy performance help decision makers track remedy progress and improve the timeliness of remedy optimization, reevaluations, or transition to other technologies/contingency actions.
By participating in this training course we expect you will learn to apply the ITRC guidance document to:
  • Identify and integrate technical and nontechnical challenges into a holistic approach to remediation
  • Use the Remediation Potential Assessment to identify whether adaptive site management is warranted due to site complexity
  • Understand and apply adaptive site management principles
  • Develop a long-term performance-based action plan
  • Apply well-demonstrated techniques for effective stakeholder engagement
  • Access additional resources, tools, and case studies most relevant for complex sites
  • Communicate the value of the guidance to regulators, practitioners, community members, and others
Ultimately, using the guidance that can lead to better decision making and remediation management at complex sites. The guidance is intended to benefit a variety of site decision makers, including regulators, responsible parties and their consultants, and public and tribal stakeholders.
Case studies are used to describe real-world applications of remediation and remediation management at complex sites. Training participants are encouraged to view the associated ITRC guidance Remediation Management of Complex Sites (RMCS-1, 2017) prior to attending the class.

TPH Risk Evaluation at Petroleum-Contaminated Sites

Interstate Technology Regulatory Council Remediation at petroleum release sites is often infeasible for technical or cost reasons. Many of these sites could be depleted in typical indicator compounds, such as BTEXN, but still heavily contaminated in terms of Total Petroleum Hydrocarbons (TPH). The traditional indicator compound approach for managing petroleum contaminants may not fully identify short- and long-term potential environmental concerns, can create delays in project schedules and cost overages for sub-surface utility work or redevelopment. It is important to consider a comprehensive cumulative risk-based approach to more effectively incorporate TPH data in addition to traditional BTEXN data for cleanup and long-term management decisions.

The basis for this training course is the ITRC guidance: TPH Risk Evaluation at Petroleum-Contaminated Sites (TPHRisk-1, 2018). The guidance builds on long-standing and current research and experience, and presents the current science for evaluating TPH risk at petroleum-contaminated sites. The methods and procedures to evaluate human and ecological risk and establish cleanup requirements in the various media at petroleum release sites will assist decision makers in developing and implementing a technically defensible approach. In addition, the guidance provides information and supplemental references to assist practitioners and project managers in the assessment of fate, transport, exposure, and toxicity of TPH. The guidance users will also gain information that may be used in conjunction with classic tiered approaches for risk-based decision making (ASTM 2015b, ITRC Risk 3 2015), including modifications in the assessment and remedial-decision and regulatory framework for TPH impacts through direct comparison to screening levels, site-specific modification of screening levels, and complete site-specific risk assessment for sources, receptors, and pathways, where appropriate.

The target audience for this guidance and training course is:
  • Regulators and Program Managers interested in knowing how site management decisions can influence the TPH risk evaluation process.
  • Risk assessors new to TPH data or those who want additional knowledge and training in the current methods and common practices for collecting and using TPH data in assessments to more accurately determine human health and/or ecological risks at petroleum-contaminated sites.
  • Stakeholders who are either engaged in redevelopment at former petroleum release sites or folks who are involved in community engagement and revitalization activities.
As a participant in this training you should learn to:
  • Recognize the ITRC document as a go-to resource for evaluating TPH risk at petroleum-contaminated sites
  • Recognize how TPH -impacted media interacts with the environment and changes over time
  • Select appropriate analytic method(s) to match site objectives
  • Apply the decision framework to determine when a site-specific target level may be more appropriate than a generic screening level for TPH
Training participants are encouraged to view the associated ITRC guidance, TPH Risk Evaluation at Petroleum-Contaminated Sites (TPHRisk-1, 2018) prior to attending the class.

  • Access to a centralized resource for information on stormwater BMP effectiveness
  • Guidance to use during post-construction BMP screening, selection, installation, operation, and monitoring and maintenance.
  • Case study examples using the guidance.
  • Answers to your questions about using ITRC's stormwater BMP tool and guidance
PREREQUISITE: BEFORE the event, please view the following videos EACH UNDER 5 MINUTES:
The panel session is intended to be a mix of interactive audience discussion and introductory material. Please come ready to ask questions and interact with the panel technical members.

In addition, panel participants are encouraged to view the associated ITRC guidance, Stormwater Best Management Practices (BMP) Performance Evaluation (Stormwater-1) Oct-18. This guidance offers the user details on post-construction BMP lifecycle processes including contracting, cost considerations, installation factors including construction challenges, inspection checklists, quality control and record drawings. It goes on to address long-term technology- and performance-based operational strategies, including aspects such as routine and non-routine maintenance. Data and information from existing publicly available BMP performance programs has been incorporated into an online BMP Screening Tool. Using site-specific pollutant treatment requirements and installation considerations, the Tool can assist the user by identifying types of BMPs that may be appropriate for a given site. The Tool also provides users summarized information on the treatment efficiency, installation requirements and maintenance issues regarding the identified BMPs, with links to access more detailed information.

The target audience for this panel event is primarily state and local regulators involved in the process of stormwater BMP screening, selection, design, installation, operation and maintenance and monitoring. Others working on post-construction stormwater management will benefit as well, particularly consultants and new staff in the stormwater industry.

During the panel event registration process you may submit questions that may be addressed by panelist during the upcoming panel event.
