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 ...

Soil Mixing- Case Study

ERC was hired as the General Contractor for this project to treat organic contaminants found in the soil via in-situ chemical oxidation (ISCO). To achieve this ERC excavated and stockpiled ...
