ABSTRACT
Aquifer remediation at a former refinery site, mainly contaminated by BTEX compounds, led to the removal of about 2400 tons of hydrocarbons e.g. 98% of the initial contamination by pumping, free product recovery and in situ bioremediation treatment. Due to risc assessment based on mass transfer and groundwater transport modelling Natural Attenuation is assumed to be feasible as final process for site remediation, enabling the containment of the plume as well as the removal of residual hydrocarbons within a reasonable time frame.
