Variabilité spatio-temporelle de la qualité de l’eau potable des petits réseaux : facteurs explicatifs et développement d'outils de gestion
This thesis focuses on the determination of factors that impact the spatio-temporal variability of drinking water quality in small systems and on the development of management tools intended to operators. Data was provided by sampling campaigns conducted in 25 small systems in two Canadian provinces...

This thesis focuses on the determination of factors that impact the spatio-temporal variability of drinking water quality in small systems and on the development of management tools intended to operators.

In the second chapter, a drinking water quality index is developed.
