Langley Soil and Groundwater Investigation and Remediation

The remediation of a heavily contaminated 26 hectare former vehicle assembly site close to Heathrow Airport. End uses for the site were to be one third residential development and two thirds commercial/industrial hard cover.  Targets for the remediation of the site were set appropriately and generally conformed to ICRCL recommendations, if more suitable, Dutch standards were used.

Die Lösungen

Soil Remediation:

53.000 m³ of hydrocarbon-contaminated soil was bioremediated in windrows/biopiles and backfilled

20.000 tons of hazardous waste (PAH and heavy metals) were specially disposed of using selected excavation

Groundwater Remediation:

The amount of l/s that was remediated was adjusted to the progress of the soil remediation.

7.000m³ of groundwater skimmed to remove free-floating product. 150.000m³ of TPH-contaminated groundwater was pumped and cleaned.196.000 m³ of groundwater was processed by air stripping and activated carbon filters to remove volatile organic compounds.
