    Air sparge system - Case Study

    ERC was contracted to install an air sparge system in Central Ohio. Air sparging is an in situ remedial technology that reduces concentrations of volatile constituents in petroleum hydrocarbons adsorbed to soils and dissolved in groundwater. This involves the injection of contaminant-free air into the subsurface saturated zone, enabling a phase transfer of hydrocarbons from a dissolved state to a ...

    Electrical Impedance Tomography System

    The EIT2000 Series system is designed for long-term monitoring of subsurface processes. The system is able to make threedimensional subsurface images using electrical resistivity tomography (ERT) or electrical impedance tomography (EIT). ERT/EIT is a proven technology for monitoring fluid infiltration and enhanced remediation technologies such as air sparging and steam-enhanced remediation.The ...
