A recent application by a steel manufacturing plant to obtain a permit for an industrial landfill located on top of abandoned soda-ash waste beds in the City of Syracuse, New York, resulted in an extensive hydrogeologic investigation. The investigation included developing a three-dimensional ground-water flow model of the soda-ash waste beds. The purpose of this study was to investigate site hydrogeology and predict the fate of leachate released by the metals manufacturing waste using a ground-water flow model. Using data gathered from the field program a three-dimensional ground-water flow model was developed for the area using the USGS Model to simulate three-dimensional water flow. Results from the investigation indicated leachate from the waste will flow predominantly vertically downward through 65 feet (20 m) of soda-ash waste before discharging into Onondaga Lake and an adjacent stream.
