Due to technical difficulties, the archive of Day 2: Fractured Rock 102: Focus on Remediation begins with the 1:00pm presentation on
Thermal Remediation in Fractured Rock - A Case Study and What to Look for in a Work Plan

Contaminated groundwater in fractured rock at Superfund sites poses unique challenges due to the geologically complex nature of such sites. Technological advances have led to the development of tools that aid in gaining a more robust understanding of contaminated fractured rock systems. The Technology Innovation and Field Services Division (TIFSD) in EPA Headquarters has collaborated with the U.S. Geological Survey (USGS) to develop an EPA-specific training course that provides a state-of-the-practice overview of the characterization and remediation of contaminated groundwater in fractured rock. This training course that will improve national consistency for these complex sites and drive the development of effective characterization and remediation techniques required for their restoration.

The USGS has collaborated with EPA to develop a training course specific to EPA Region 10 (Pacific Northwest) that will highlight information requirements for characterizing the spatial distribution and fate of chlorinated solvents and their degradation products in complex fractured rock environments. The USGS has developed several workshops/training sessions for EPA in the past and these previous efforts provide the foundation for this current effort. EPA HQ and Region 10 personnel have worked closely with the USGS to ensure that Superfund specific content is included throughout the course sessions.

The two-day workshop will take place on September 11-12, 2019, at the Region 10 Office in Seattle, WA and is available to remote viewers via CLUIN.

Day 1: Fractured Rock 101: Focus on Characterization
The first day of the course will provide an overview of groundwater flow and contaminant transport processes in fractured rock environments. The focus will be on field characterization of fractured bedrock. Topics will include characterization of the hydrogeology, contaminant distribution, and transport processes and pathways in the fractured bedrock. Case studies of Region 10 (Pacific Northwest) sites will be highlighted to illustrate the characterization of groundwater contamination in fractured rock systems.

Day 2: Fractured Rock 102: Focus on Remediation
The second day of the course will focus on remediation of groundwater contamination in fractured rock systems. Case studies will illustrate multiple remedial approaches for cleaning up contamination in fractured rock systems.

Presenters will include USGS, EPA, Oregon DEQ, and industry representatives.
