ABSTRACT: This study examines sewage lagoons and their operations in remote locations, including facilities located within military bases where the metal levels are required to be monitored in order to ensure due diligence. The scope of this paper is: (1) to summarize the current performance of a particular Canadian Armed Forces (CAF) sewage lagoon system located in the Canadian Prairies with regards to the removal of metals such as mercury, arsenic, copper, lead, zinc and cadmium from the effluent, and, (2) to present our preliminary results regarding the factors that may influence the effective removal of metals under various environmental conditions. The research adopts a laboratory comparative batch study in order to investigate the behaviour of the metals of interest within synthetic wastewater under varying pH conditions and temperatures, with a view to simulating average summer and winter conditions. Mass spectrometry will be used in the quantitative data collection and analysis, while observations and interviews will be employed for qualitative data collection and analysis. The overall expected outcome is to add value in terms of good operation and management practices of sewage lagoons, particularly regarding effluent quality and metal levels.

RÉSUMÉ: Cette étude examine les lagunes des eaux usées et leurs opérations dans des endroits éloignés, y compris les installations Le présent document a pour objet: (1) environnementales. La recherche adopte une étude comparative en laboratoire pour étudier le comportement des métaux et de gestion des lagunes des eaux usées, en particulier en ce qui concerne la qualité des effluents et les niveaux de métal.
