Column Studies for In Situ Remedy Design and Evaluation

2018 MSECA Sponsors
MSECA appreciates the support of our annual sponsors in helping us to bring great education to our membership.



Program Summary:

Presented by:

Bernd Rehm, ReSolution Partners

Session Description:

Column studies can be an important supplement to batch trials by evaluating potentially viable remedies under dynamic (flowing) conditions at soil to water ratios representative of in situ conditions. They are typically used to assess in situ stabilization remedies that are implemented below the water table as emplaced permeable reactive barriers (PRBs) or injected permeable reactive zones (PRZs). Columns can be applied to both aerobic and anaerobic settings with appropriate sample collection and handling. Soil and groundwater sample requirements are greater than batch studies. Column results can be used to assess in situ stabilization robustness and longevity, and reagent content and residence times of PRBs and PRZs.

Learning Objectives:

  1. Why columns can be useful for in situ remedy evaluation and design.
  2. What is required for successful column studies.
  3. How are column results used (i.e., project examples).

Bernd W. Rehm received a MS in hydrogeology from the University of Waterloo in 1977. After 27 years in research and consulting with projects ranging from solvents in karst aquifers to mercury in sediments, he and Angela Hassell established ReSolution Partners in 2004. ReSolution Partnersí focus on remediation technology extends from treatability studies in the Madison, WI laboratory to remediation design and full-scale implementation with projects across the United States and in Brazil, China and South Africa.
