Soil Mixing for Trichloroethylene
ETS has utilized oxidant soil mixing technology to reduce concentrations of Trichloroethylene (TCE) in the soil below soil saturation limits. This method has proven highly successful and allows the remaining impacted soil to be managed in place in accordance with state regulations. By mixing in place, waste profiling and costly hazardous waste transportation and soil disposal can be avoided.
Potassium Permanganate was used as the oxidizer for the chemical reaction with the TCE to reduce concentrations. As the soil and permanganate are mixed the soil temporarily turns a vivid purple color.
As the excavator mixes the soil and the potassium permangante together, the mix is hydrated to start the reaction.
