overview of compounds that can be oxidized
Overview of Compounds that can be Oxidized:
  • MTBE, TBA
  • Chlorinated solvents (PCE, TCE, DCA)
  • Polychlorinated Biphenols (PCBs)
  • Pentachlorophenol (PCPs)
  • Solvent stabilizers
  • Free product or hot spots
  • Fuel hydrodcarbons and BTEX
  • Pesticides (DDT, DDE, etc.)

chemical oxidation
Chemical Oxidation
  • BEST MAP FOR SUCCESS:
  • Bench test and chemical evaluation using soil and
  • groundwater data:
  • TOC, pH, alkalinity, iron content, contaminant
  • concentrations, temperatures, other data
  • Pilot Scale Test –field test with soil and
  • groundwater confirmation testing
  • 3) Full Scale Remediation

Environmental Bio-Systems, Inc.

selected remediation case studies
Selected Remediation Case Studies:
  • In-Situ Oxidation of TCE, PCE in Soil and Groundwater
  • In-Situ Oxidation of Hydrocarbons in Groundwater
  • In-Situ Oxidation of PCE in Soil
  • In-Situ Oxidation of Free Product
