OH- Compaction: The Enemy of System Longevity - Dr. Sara Heger (1 hr.)

This presentation discusses the causes of compaction including wet soils, material handling and the the weight of vehicles/equipment, pedestrians, and animals. It will then focus on avoidance methods and potential solutions for sites have been compacted including advanced treatment systems.Humans along with all our activities cause widespread soil compaction. Compaction constrains oxygen (O2) movement in the soil and shifts soil toward anaerobic conditions. Less O2 diffusion into the soil leads to a chemically reducing soil environment. Compaction leads to smaller pore spaces and slower infiltration rates.

Learning Objectives

  • Discuss why compaction is a problem in a soil treatment area
  • Identify methods to remediate a soil treatment area not performing properly.
  • Explain why a mound may be surfacing at the media/sand interface versus the original grade.
  • Discuss how different distribution methods affect bio mat formation
