Abstract
Control technology needs for geothermal air emissions other than hydrogen sulfide have not been considered in federal geothermal research programs, nor to a great extent by private developers. This study (sponsored by the U.S. Environmental Protection Agency under EPA Contract 68-03-3025, Work Assignment SDM-04) was designed to identify the potential emission points, resulting concentrations in ambient air, and the impacts on the environment in the vicinity of geothermal operations. This paper presents the results of the study in which ammonia, arsenic, benzene, boron, fluoride, hydrocarbon (other than benzene), mercury, radon, and sulfur oxide emission information was compiled for over 40 national and international geothermal development sites. The emission points within the geothermal processes, the compounds emitted and the need for control technology are discussed.
