In order to obtain an evaluation of the environmental impact of a proposed artificial marine island of deposited fly ash a comprehensive research project has been carried out by the Water Quality Institute in cooperation with other institutes. The project involved a number of field investigations designed to yield the information required to predict emissions and ensuing ecotoxicological effects of such an island. This paper treats some project activities which were performed in pursuit of data needed for estimating emissions from various stages of a marine ash island: Dry fly ash characterization, monitoring of operating ash ponds, investigations at old ash ponds, and laboratory leaching test. The results may be used to describe and evaluate emissions from various forms of marine fly ash disposal.
