Groundwater High-Resolution Site Characterization (HRSC)
Hosted by U.S. EPA
Office of Superfund Remediation and Technology Innovation

The Groundwater High-Resolution Site Characterization (HRSC) training course focuses on groundwater characterization and discusses (1) the impacts of subsurface heterogeneity on the investigation and cleanup of groundwater and related media, (2) the need for scale-appropriate measurements and adequate data density, and (3) the tools and strategies that are available to overcome the impacts of subsurface heterogeneity. The course addresses the following technical content:

  • Defining and explaining the need for and benefits of HRSC
  • Understanding the sources and attributes of subsurface heterogeneity and their impact on hydrogeology, contaminant fate and transport, and source and plume relationships
  • Defining and using scale-appropriate measurements, adequate data density and collaborative data sets
  • Explaining the application of HRSC to the characterization of integrated media, including: groundwater, soil, soil vapor, surface water, sediments and bedrock
  • Evaluating potentially applicable tools for subsurface investigations of shallow unconsolidated environments, deep unconsolidated environments, fractured and porous media, and the groundwater and surface water interface
  • Developing effective HRSC implementation and investigation strategies
  • Managing and visualizing HRSC data for decision making
  • Applying HRSC to remedy design, implementation and optimization

After taking this course, participants will be armed with information that will allow them to improve their subsurface investigation approaches and develop more realistic and comprehensive conceptual site models (CSM). CSMs developed based on HRSC strategies and tools will decrease site uncertainty, improve the remedy selection process for groundwater remedies, and better enable the evaluation, design, and implementation of targeted in situ and ex situ groundwater remedies.

The Groundwater HRSC course is an advanced 2-day course. The recommended audience includes EPA, federal, state, tribal and private industry technical project managers, practitioners and other stakeholders involved in groundwater investigation and remediation.

*This course is offered free of charge to all registrants who are confirmed to attend.*

Important Notice: Due to the content presented during a CEC course and the restrictions in place for non-citizens to enter federal buildings, international attendees are not permitted to attend CEC courses.
