Breakfast included.Course Overview:
Permeable reactive barriers (PRBs) are designed to create an in situ permeable reactive treatment zone perpendicular to groundwater flow intercepting and remediating contaminant plumes. Contaminants maybe treated through a series of physical, chemical and biological processes. Depending on the type of contaminants impacting the PRBs, the reactive zone may be created using reagents based on permanganate or persulfate to promote chemical oxidation (ISCO) of contaminants or substrates like Zero Valent Iron (ZVI) to promote chemical reduction (ISCR) or indirectly, using materials designed to stimulate secondary processes (e.g., adding carbon substrate and nutrients to enhance microbial activity).
This presentation will describe the basic concepts of designing an ISCO/ISCR PRB applied to address mass flux of organic contaminants migrating through a zone of concern with an emphasis on treatment of chlorinated organics.
This 2-hour course will be presented as two parts:
Part 1 (1 hour)
- Introduction and principles of PRBs
- ISCR technologies applied in a PRB configuration
- Critical Parameters for ISCR PRB design
- ISCO technologies applied in a PRB configuration
- Critical Parameters for ISCO PRB design
Part 2 (1 hour)
- Bench scale data to evaluate ISCO/ISCR reagents
- ISCO vs ISCR PRBs
- Combined Remedies - Advances in PRB technologies
- Case studies
