Tank Farm Investigation and Remediation

Discovery and containment of a mineral-oil hydrocarbon contamination on a tank farm (8000m²), risk assessment, preparation and execution of remediation measures

Services performed:
Investigation: Planning and execution of a total of 50 percussion drills and installation of 8 groundwater monitoring wells incl. analysis and reporting. Soil and soil-gas sampling, water sampling, geodetic measurements, groundwater level measurements, preparation of groundwater models and geological profiles, preparation of damage charts for the saturated and unsaturated soil zone.

Remediation: Planning and performance of Ex-Situ remediation measures – Preparation of a remediation plan, excavation to 8 m bgl with water retention – environmental technical excavation supervision; Disposal of ca. 6.550 t contaminated soil.

Groundwater-Monitoring: periodic groundwater sampling and analysis at the existing groundwater measuring points to guard against contaminant drift from the contamination still present under the tank farm (part of the remediation plan)
