Summary: | The study reported herein involved investigations of microorganism survival under ice conditions downstream of the Fort Smith, N.W.T., wastewater disposal site. The Fort Smith wastewater treatment and disposal system consists of two primary lagoon cells and a facultative cell, followed by a continuous discharge to the Slave River through a submerged near-shore outfall.Microorganism sampling and analyses for total and fecal coliforms were conducted for each sampling station. After accounting for the physical dilution the limited data showed a barely discernible microorganism die-off within the study reach for the ice-covered conditions. Key words: mixing, coliform bacteria, dilution, sewage disposal, outfall sewers, fluorescent dye, indicator species, stream pollution. |
