  • Tracer study to verify hydraulic limits and determine water residence times in a distribution system: Part I

    This study introduces a methodology for assessing the residence times of drinking water in distribution systems using a tracer. The injection of a tracer followed by an intensive sampling campaign was used to evaluate the residence times of water in Quebec City's main system, which is supplied by the St Charles River. Samples were also analysed to determine the hardness and conductivity ...
