Title: Borehole Diffusive Flux Apparatus


Invention: This invention characterizes contaminant plumes.


Background: Removing contaminants from groundwater involves significant time and cost because contaminants spread in a plume through general water movement and specific contaminant diffusion. Mixtures of soils with different permeabilities can lead to back-diffusion complications, as contaminants travel from areas of untreated low-permeability to high-permeability soil already treated. Such information allows for remediation strategy planning most applicable to local conditions.



  • Groundwater remediation



  • Clear characterization of local contaminated site condition changes
  • Better understanding of permeability differences and diffusive flux
  • Real-time and continuous data tracks trends and progressions
  • Variety of testing techniques available through access to sampling point
  • Expands on current borehole testing processes to minimize remediation uncertainty
