Gregory Granato is a hydrologist whose research focuses on developing hydrologic software to provide actionable information for environmental decisionmakers. Gregory has worked with the USGS on projects covering all aspects of hydrology since 1992. Before that time he was an aerospace engineer working on the design of the Space Station's water and waste treatment systems.

The quality of water in unsaturated zones and groundwater is affected by the major ions in deicing chemicals applied to roads and highways. The assessment of the environmental effects of highway runoff requires investigations to determine whether other major and trace constituents are mobilized during deicing chemical migration through the...
