This wastewater sampling campaign in the south-east interceptor aimed to determine the acute lethality and the physicochemical quality of the water discharged into the river without treatment during the work carried out on the south-east interceptor between 11 and 14 November 2015. The document...

During the month of November 2015, the City of Montreal carried out major maintenance work on the south-east interceptor, which required the latter to be put out of work. The result was a wastewater discharge whose duration and volume were estimated.

As part of the COURDO program, the RSMA (Network for Monitoring the Aquatic Environment) aims to document the general quality of the waterways surrounding the territory of Montreal. This data set contains [special data collected in addition to the regular COURDO program]...

The Plan of Land Use and Development of the Agglomération de Montréal indicates a target aimed at increasing the protected land area to 10%. This objective is reiterated in the 2020-2030 Climate Plan and the Nature and Sports Plan as part of the Montréal 2030 strategic plan. In 2023, the...

The main objective of this sampling program was to assess the potential effects of the spill on plant quality by comparing the results of analyses of samples taken during and after the spill with those taken before. The distribution of the stations aimed to assess the impacts of the spill in a...

Atmospheric concentrations of metal pollutants sampled on the island of Montreal. This program is part of the activities of the Air Quality Monitoring Network (RSQA) and improves the monitoring of the presence of [gaseous air pollutants] (. /rsqa-gas-pollutant). The set shows the metal...
