Landfill Investigation using sonic drilling in Geelong, Victoria
South Western Drilling was engaged to provide direct imaging technology to log VOCs at a former landfill.
Our client was targeting LNAPL, DNAPL, dissolved phase hydrocarbons and landfill gas. The MIP also gives a continuous geological profile via real time EC data.
Our client could map the depth of the clay cap and the relative concentrations of landfill gas below the cap. LNAPL and DNAPL were also detected. The EC detector could provide an accurate depth to the clay liner and ensure the liner was not penetrated during the investigation, this data enabled us to drill and install leachate wells with our sonic drilling rig with confidence, knowing the target depths of all new wells prior to delivery of the sonic rig to site.
