Method and apparatus for depositing a chemical over a body of water. In one embodiment the invention includes collecting and concentrating a floating contaminant between two floating booms pulled by one or more surface vessels. The booms define an aperture intermediate of their endpoints, and the towing of the boom results in the flow of concentrated contaminant through the aperture. One or more nozzles proximate the aperture deposit a chemical, such as a liquid dispersant, on the contaminant and water flowing through the aperture. Some embodiments also include a mixing apparatus placed at aft of the aperture for inducing mixing of the deposited chemical and the floating contaminant.
