You can “efficiently delineate multi-component dense non-aqueous phase liquids (DNAPLs) with a subsurface screening service.” It uses TarGOST (Tar-specific Green Optical Screening Tool) to detect bunker fuels, coal tars, and creosotes, it’s announced. Other contaminants capable of being screened include crude oils, bunker fuels, heavy distillate, dripolene, biodiesel, and some plasticizers.
TarGOST uses visible wavelength laser-induced fluorescence (LIF) technology to detect polycyclic aromatic hydrocarbons (PAH) found in multi-component DNAPLs, difficult to screen using ultra-violet wavelength LIF systems.
Producing 10 to 12 readings per foot, the unit identifies the heterogeneous distribution of coal tars and creosotes — which is otherwise challenging to delineate by traditional samplings methods.
TarGOST is deployed via direct-push platform. For each location a detailed, colorized log is generated to show presence of tar/oil DNAPL versus depth.
