Nanoscale and Microscale Zero Valent Iron (Fe°) Treatability Studies

Nanoscale and microscale zero valent iron (Fe°) are emerging remediation technologies used to degrade recalcitrant chemicals by reductive processes. SiREM Fe° treatability studies are designed to address site specific needs in order to optimize your remediation program.  The parameters typically evaluated in Fe° treatability studies include:

  • Design loading rates;
  • Applicability of Fe° to specific compounds of interest; and
  • Comparison of Fe° and emulsion formulations, sources or vendors.

SiREM has performed nano-Fe° treatability studies for potential application at variety of Federal and private-sector sites.  Our work with nano-Fe° has demonstrated effective and often rapid treatment of numerous groundwater pollutants including:

  • Trichloroethene and dichloroethene
  • Carbon tetrachloride and chloroform
  • 1,1,1-Trichloroethane
  • Trichlorofluoromethane
  • Ethylene dibromide
  • Nitrate
  • N-nitrosodimethylamine (NDMA)
  • Trichloropropane
