Ville de Québec – Service du traitement des eaux
This project aims to better protect the health of people working in wastewater treatment plants by reducing their exposure to aerosols generated during treatment processes. These airborne particles can contain bacteria responsible for respiratory and digestive problems.
The research team will analyze the air in 15 facilities across Quebec to identify the bacteria present and assess the associated health risks. Simulations will also be used to understand how the characteristics of wastewater influence the formation of these aerosols. At the same time, real-world occupational exposure—often in enclosed, poorly ventilated environments—will be measured.
The results will be used to develop a simple, practical online tool to help assess risks and implement effective preventive measures. This project will help reduce occupational illnesses, absenteeism, and healthcare costs, while improving working conditions and the attractiveness of jobs in Quebec’s water treatment sector.
