 Spatial Analysis of a Wastewater Effluent Plume, Bow River, Alberta Track: Water, Wastewater, and Stormwater Author(s): David Nuell, Cathy Ryan, Jerry Vandenberg Bonnybrook wastewater treatment plant is the first major point source discharge into the Bow River. Across fifty transects downstream of the outfall, we measured electrical conductivity in-situ and collected samples for laboratory analysis of chloride, nitrate, ammonia, phosphate, and fecal coliforms. Parameters were mapped to determine the extent of transverse mixing. Representing the plume in real coordinates was problematic due to interpolation methods that do not account for river meanders. We transformed coordinates into a rectilinear system that reduces the errors incumbent with a meandering river. The two-dimensional output facilitated a better understanding of the dynamics of the effluent plume.
