Would you like to know how Montréal monitors water quality in aquatic environments? Learn about the methods it uses to monitor wastewater discharged into waterways? Here’s what you need to know.
The city has created several ways to monitor water quality in Montréal. Reduction at source of pollutants, wastewater discharge controls and monitoring aquatic environments help protect ecosystems and biodiversity.
Permits for companies
Before discharging wastewater or contaminants, companies and dental offices must request a permit. To receive one, they must provide the city with proof that their equipment complies with the criteria for obtaining a permit and current regulations. Once a permit has been granted, the city will verify that regulatory requirements and standards are respected. For example, it may take samples to measure the quantity and nature of pollutants discharged.
Immediately notify the city of an accidental discharge. The causes of the discharge as well as measures implemented to prevent it from recurring must be provided within 15 days.
Aquatic environment monitoring network
The Réseau de suivi du milieu aquatique (RSMA) conducts analysis and monitoring at more than 500 sampling stations in Montréal. Through various programs, the monitoring network evaluates quality in waterways (COURDO), at shorelines (QUALO), in streams and other inland waterways (RUISSO) and rainwater (PLUVIO). Sampling results on specific dates are published via a map (in French). Parameters analyzed (in French) and the network annual report (in French) can be consulted on-line.
Reporting an issue
You can report a situation relating to a waterway or sewer that seems abnormal or suspicious. Complaints are analyzed within 24 working hours, or on Monday if they are sent during the weekend. In case of an emergency, a team will go to the site rapidly. You will be advised of the measures taken.
