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 2’ of overburden soils from the treatment area then utilized a 336sized excavator with a mounted transverse mixing head attachment to perform in-situ soil mixing on an approximately 9,943 square feet area to depths 8-10 feet below ground surface.  During the soil mixing operations, ERC mixed the reagent with water in poly tanks and then applied the soil amendment with a metered pump to control application quantities.  We took extra precautions while working below the overhead lines and around the power poles on site.
