Remediation of a petroleum hydrocarbon contaminated site at a lubricating oil factory in Kaohsiung, Taiwan (STARx pilot)

The most contaminated zone waslocated at 3.0-3.5m bgs under lubricating oil mixing area (water table at 3.4mbgs), and the largest contaminated area was located at 5.5-6.0m bgs under crudeoil processing plant (below water table).

Oil sludge and petroleum hydrocarboncontaminated soil: TTZ with contaminant concentration < 5000mg / kg：75045m³,TTZ with contaminant concentration > 5000mg / kg: 31270m³;COCs removal rate in pilot: > 99%
