Workshops

Workshops are scheduled for Thursday, April 11, 2019.

  1. Conceptual Site Model Development and Translation to Numerical Models
    Instructors: Vicky Freedman and Mike TruexGroundwater management requires understanding of the full system so that impact of potential actions can be identified. A first step in gaining this system-level understanding is to integrate multiple physical, geochemical and microbiological factors into a conceptual site model (CSM). A CSM is a tool that identifies and organizes factors important to a site and describes the site-specific environmental setting, contaminant properties, and risks to provide a basis to select an appropriate remedy or management action. As such, the Conceptual Site Model is a core tool for environmental management, starting at the onset of site characterization and continuing in usefulness until the site action is completed. In many cases, to apply the CSM for remedy decision-making and design, the CSM must be translated into a quantitative description of the site as a numerical flow and transport model.This workshop will present how 1) site data are mapped into numerical models; and 2) CSMs are used to build numerical models describing saturated and unsaturated flow and transport. The first half of the workshop will include a presentation of CSM approaches and supporting tools, with interactive elements to allow discussion of participants’ specific concerns. In the second half of the workshop, the course will demonstrate how the CSM site-specific information is integrated into numerical models using a freely available graphical user interface that allows the user to visualize the model domain (e.g., boundary conditions and geologic materials). The focus will be on identifying the level of modeling complexity needed to adequately represent the CSM. Decisions on simulator selection, numerical considerations (e.g. grids), heterogeneity and numerical approaches will be evaluated with respect to the CSM and data requirements. Hands-on demonstrations of different modeling approaches will be an integral part of understanding the CSM translation to the numerical modeling framework.Laptops will maximize the workshop experience, but not required.Hotel Murano Venice Rooms, 8:30 AM – 4:30 PM

  1. ITRC Guidance: Remediation Management of Complex Sites
    Instructors: Elisabeth Hawley, P.E. (Geosyntec Consultants) Mike Truex (Pacific Northwest National Laboratory) John Price (Washington State Department of Ecology)Objective: This course will provide a framework based on adaptive site management principles for remediation management of complex sites. It will also identify and integrate technical and nontechnical challenges into site objectives, remediation approach, and develop a performance based action plan to guide long-term management. This training will interest state and federal regulators at complex sites, environmental professionals, and public and tribal stakeholders.Overview: 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 short course and associated ITRC guidance, Remediation Management of Complex Sites, provide a recommended process for remediation management at complex sites, termed “adaptive site management”. Adaptive site management is a
    comprehensive, flexible, and iterative process of remediation management that is well-suited for complex sites, where there is significant uncertainty in remedy performance predictions. Adaptive site management includes periodically evaluating and adjusting the remedial approach, which may involve multiple technologies at any one time and changes in technologies over time. Comprehensive planning and scheduled periodic 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. Participants will learn how to apply the guidance to improve 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 will be used to describe real-world applications of remediation and remediation management at complex sites.

  1. Understanding and Addressing Well Performance Issues
    Instructors: Jim Bailey and othersProblems with well performance are usually preventable, often start with well construction and development, and are then exacerbated by water quality conditions, well operation and rehabilitation efforts. This presentation will discuss the key factors affecting well performance including new well design, initial screen development, biological and mechanical plugging, well operation, and rehabilitation methods. An asset management based approach is described that helps prioritize maintenance decisions and long term well field operation.Over the past several years there has been significant research done worldwide related to optimizing well performance. This research has included looking at the mechanisms involved with biological and mechanical plugging of aquifers, and the effectiveness of various rehabilitation technologies. The presentation will also discuss several studies in Europe that looked at the mechanisms associated with poor well performance and innovative approaches being used to prevent or correct poor well performance.

Field Trips

    1. Hydrogeology of Elwha River – Stream Restoration, full day, Monday, April 8, 2019Elwha River Restoration is a National Park Service project that includes the removal of two large dams on the Elwha River, restoration of the Elwha watershed, its native anadromous fish, and the natural downstream transport of sediment and woody debris. Dam removal began September 19, 2011 and concluded in the summer of 2014.The Elwha project, including dam removal, restoration efforts, and protection measures, is serving as a “living laboratory” for monitoring large-scale ecosystem recovery and investigating particular ecosystem processes and components.The project provides a rare opportunity for scientists to learn what happens when a dam is removed and salmon return to a wild, protected river. Among the researchers are fish and marine biologists, botonists, entomologists, geologists, ornithologists, and students.Scientific monitoring and analysis for the project is led by the U.S. Geological Survey (USGS), in coordination with the Olympic National Park, Lower Elwha Klallam Tribe, the Bureau of Reclamation, Washington Department of Fish and Wildlife, U.S. Fish and Wildlife Service, the Environmental Protection Agency, the National Oceanic and Atmospheric Administration, and other local and state entities.

      8:50 AM: Meet in Hotel Murano lobby.
      9:00 AM: Vans will depart from in front of the Hotel Murano.
      Noon: Arrive back at hotel.

    2. SR 530 Slide, full day, Monday, April 8, 2019
      Oso, Washington
      USGS has responded to the SR530 landslide disaster with scientific support provided to first responders and local and regional decision-makers. In addition to short-term scientific information needs arising from this event, questions related to ongoing impacts of SR530 landslide are emerging. Predicting, assessing, measuring, and monitoring the movement of sediment through the flood-prone, ecologically sensitive reaches from the landslide to Puget Sound is paramount. In addition, assessing the long-term stability of the river channel through the landslide deposit and understanding the feedback of river migration to landslide initiation is critical to predicting sediment transport and assessing future landslide risk.The Washington Hydrogeology Symposium field trip will visit….TBD. The field trip will focus on aspects that resulted in slope failure and resultant geomorphological changes.Scott Anderson, will lead the tour and discuss relevant research.

      11:50 AM: Meet in Hotel Murano lobby.
      Noon: Vans will depart from in front of the Hotel Murano.
      5:00 PM: Arrive back at hotel.

      Cost: $10.00
