The feasibility of using hydrocarbon vapor sensors on buoys along watercourses for the signalling of oil spills on a real time basis has been investigated. As a result of laboratory testing of five types of vapor sensors, it was concluded that the Taguchi Semiconductor Gas Sensor TGS was promising for this application. Two other vapor sensors selected by the U.S. Coast Guard for further investigation were the Esso oil on water piezoelectric sensor and the Environmental Measurement Systems Adhistor sensor WSM-350. These three sensors were evaluated in the laboratory, in the rooftop environment, and in a lake environment. The TGS sensor and the Adhistor sensor were also investigated in the marine environment. Recommendations for further testing and evaluation of the TGS sensor on buoys are made.
