Remediation of groundwater using soil vapour extraction, Australia

Share on:

A large underground fuel leak at a regional service station resulted in an off-site plume of light non-aqueous phase liquid (LNAPL) up to 100m long.

Soil vapour extraction (SVE) was selected by GHD as the preferred remediation option. After successful pilot trials, GHD oversaw the installation of a full scale SVE system comprising eight extraction wells, and vapour stream treated using an internal combustion engine. During the first six months of its operation the system had removed approximately 16 tonnes of LNAPL.
