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.

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.

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.
