SourceKill℠ is RemQuest's enhanced version of NASA's emulsified zero-valent iron ("EZVI"). We created a better emulsion for faster results!

SourceKill℠ is a water in oil emulsion consisting of nano/micro scale zero-valent iron, surfactant, food-grade vegetable oil, and water that reductively dehalogenates halogenated hydrocarbons (e.g. PCE, TCE, CFC, VC). SourceKill℠ is manufactured specifically to create an emulsion of micelles that matches the physical chemistry of DNAPLs to deliver reactive iron particles, enabling full miscibility with contaminants in the subsurface. Thus, SourceKill℠ is a source area remediation technology.  

  • Developed/patented by NASA
  • Field-tested by the U.S. EPA under the SITE Program
  • Primarily used for in-situ DNAPL source area destruction
  • Typical source concentration decrease ~90+% within 3 months
  • The only surfactant-stabilized water-in-oil emulsion containing zero-valent iron particles
  • Hydrophobic, dense emulsion absorbs DNAPL, delivering contaminant to iron
  • In-situ chemical reduction of chlorinated solvent to ethene and water
  • Injection or soil mixing using conventional technologies
  • Does not promote mobilization of DNAPL
  • RemQuest is the largest custom manufacturer/supplier of SourceKill℠, providing reactive, stable emulsions since 2005
