Introduction to Groundwater High-Resolution Site Characterization (HRSC): This live two-part webinar series is an introduction to HRSC. The introductory sessions address the following technical content:

  • Defining HRSC and how it is implemented
  • Explaining the need for and benefits of HRSC
  • Reviewing the eight components of the CSM and how HRSC informs the CSM
  • Refresher of basic hydrologic properties and how these properties vary within geologic systems
  • Refresher of the principles of contaminant fate and transport and how these characteristics affect the distribution of contaminants in the aquifer
  • Conceptual site models of fate and transport in unconsolidated and fractured rock
  • Introduction to the challenges of characterizing contaminant distribution in fractured rock

After taking this webinar series, participants will be prepared to dig deeper into the uncertainties created by traditional sampling approaches and learn how HRSC can address these challenges in the in-person HRSC course.

Each webinar will be 2.5 hours long. The recommended audience includes EPA, federal, state, tribal and private industry technical project managers, practitioners and other stakeholders involved in groundwater investigation and remediation.

SPECIAL INSTRUCTIONS FOR THOSE TAKING THE THREE DAY IN PERSON CEC GROUNDWATER HRSC COURSE: This live two-part webinar series is a prerequisite for those wanting to attend the three-day in-person CERCLA Education Center (CEC) Groundwater HRSC course. If you are not able to attend the live webinar series, it will be recorded and a link to the recording will be provided to those registered to attend the classroom training that will allow you to listen at your convenience prior to the classroom delivery. If you have any questions regarding the webinars, please feel free to contact Jodi McCarty, ICF at jodi.mccarty@icf.com.
