IN-SITU CHEMICAL OXIDATION USING JETTING DELIVERY TECHNOLOGY Environmental Bio-Systems, Inc. Jim Jacobs, RG, REA, CHG Environmental Bio-Systems, Inc.
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.) Environmental Bio-Systems, Inc.
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: • 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 Environmental Bio-Systems, Inc.
