Impurities are removed from the surface of a liquid by impinging an elongated fluid stream, preferably a gaseous stream, along a length of the surface and moving the impinging stream relative to the surface causing the impurities to move and concentrate in advance of the impinging action of the stream, and thereafter isolating the concentrated mass of impurities. An apparatus is also provided suitable for traversing a body of water and recovering impurities, such as oil and the like from its surface. A preferred apparatus includes a vessel having a pair of elongated booms which are adapted to extend forwardly and outwardly of the motion of the vessel. Each boom extends above the water and carries nozzles which are adapted for form a substantially continuous elongated gaseous stream for impinging upon the water between the booms to thereby concentrate floating impurities between the booms. In addition, the vessel is provided with impurity inlet means between the booms for collecting the concentrated impurities from the water.
