The field site: Akacievej, Hedehusene

Description of the field site, spill history, overview

  • Former dry cleaning facility in Denmark (1973-2003)
  • PCE spill in 1976 → dissolved plume with ca. 400 m length
  • Excavation of most polluted soil (DNAPL) in 2006
  • Installation of a pump-and-treat remediation system in 2007: pumping with 2.5 m3/h, treatment with activated carbon and reinfiltration

Remediation system and contaminant plume in 2006 and 2015

Conceptual model development

The setup of the conceptual model for the Akacievej field site is going to be explained.

Geologic model

Geologic model, hydrogeology, contaminant distribution etc.

Geology at the Akacievej site

Flow model

Flow field at Akacievej determined by head measurements.

Contaminant distribution and dynamics

PCE concentration measurements before, during and after the pumping test, combined with previous investigations. Modeling interpretations and conceptual model of the plume propagation.

PCE distribution at Akacievej during remediation
