The project site experienced LNAPL spills in the recent past. In the
characterisation of the site it was necessary to investigate the physical properties
of the vadose and saturated zones. It was found that temperature, saturation,
phase-distribution, the hydraulic properties and water levels contributed to the
LNAPL being vaporised. The attributes of the soils substantiated the vaporisation
model. The geology was found to be dominated by interbedded sandstones and
mudstones, underlain by a dolerite sill. The pollution plume was delineated at the
study area and an appropriate management plan was proposed for the site. MNA
was shown to be an effective management option.
