A simple and inexpensive device with no moving arts for removing from a well non-aqueous liquids, such as gasoline or crude oil, that accumulate on top of the water table in the well comprises a buoyant elongated member, such as a plastic tube sealed at both ends, and a hydrophobic sorbtive material preferably attached to the outside of the tube. The buoyant device is lowered into the well where it floats either in the non-aqueous liquids or in the water such that the sorbtive material is in contact with and absorbs the non-aqueous liquids from the surface of the water. The buoyant device is then removed from the well, the spent sorbtive material replaced with fresh sorbtive material and the device again lowered into the well for further removal of non-aqueous liquids.
