A method for controlling odor in a waste water lagoon comprises the steps of aerating a top horizontal layer of a lagoon adjacent its upper surface at a depth of approximately 12 to 24 inches by introducing air through a plurality of nozzles submerged in the layer to create a plurality of air bubbles in the layer. The nozzles are moved horizontally through the layer. A device for controlling the odor in waste water lagoons includes a support structure with an elongated boom operatively secured to the support structure and extending outwardly therefrom to operatively contact water in an adjacent lagoon. Compressed air is delivered through a plurality of downwardly extending nozzles on the boom into a layer of water on the top of the lagoon approximately 12 to 24 inches deep. Power elements are secured to the boom to cause the boom to move horizontally with respect to the lagoon while the compressed air is being delivered through the nozzles.
