Abstract:
A device and method for determining the depth of contaminant of petroleum based products in a subsurface, such as after an oil spill. The device is implemented either as a manual probe or as attachment to excavating equipment. The device has an ultraviolet radiation source for irradiating waves into the subsurface, and a visible-light detector for receiving fluorescence, which is induced by the contaminant when the contaminant is exposed to the ultraviolet radiation.
