This project was produced in partnership with the Construction Engineering section at 14 Wing CFB Greenwood. A key component of the Geographic Sciences program at the Centre of Geographic Sciences (COGS) is an industry partnered research project. 

​

This project focused on aircraft deicing, a routine safety procedure in which a glycol based chemical fluid is applied to aircraft at CFB Greenwood. GIS analyses were used in this project to determine and map annual and historic averages of glycol concentrations found in surface areas and outfall locations. A GIS transportation network was also produced to identify the flow of glycol fluid from source points (deicing locations) to outfall locations surrounding the airfield. Finally, Environment Canada policies, and local, national and international documents surrounding aircraft deicing were investigated throughout this project.

​

Infrastructure data were provided by the Construction Engineering section at 14 Wing CFB Greenwood, as well as water sampling records, provided by DND Water Fuel and Environment Technicians.  Data were added to an organized infrastructure geodatabase, along with supplemental topographic data such as water features and property parcels, available for download on the NS government website. The water sampling records were organized and combined into MS Excel, identified by unique sampling sites. A sampling site point shapefile was produced and the Excel records were joined to the data and overlaid on the topographic map, symbolized to highlight the areas that receive higher glycol concentrations. By identifying the locations in the study area that receive higher amounts, and through modelling the direction of resource flow, it was possible to determine the ideal locations for aircraft deicing, from an environmental perspective.
