The project has revealed that the effectiveness of corrosion control treatments implemented by utilities needs to be evaluated, as well as the practice of partially replacing lead service lines by municipalities, as evidence suggests that this practice increases lead release.
This research was designed to document transient pressures that may be caused by standard maintenance operations such as pumping, flushing or break repairs, and to examine their impact on water quality.
The need for novel microbial monitoring tools across Canada to prioritize multi-barrier protection of water supplies is clear; however, Canada lacks a mechanism to facilitate and accelerate uptake by industry. This work aims to address the need for such a mechanism by creating and piloting a Microbial Test Translation Pipeline that will enable rigorous [...]
This project investigated the short- and long-term impacts of partial lead service line replacements on lead leaching into tap water at bench, pilot and field scales over a period of three years. The experiments and monitoring were conducted in households and water utilities in four municipal distribution systems in Halifax, Montreal, Ottawa, and London.
This project examines the interrelationships of source water chemistry, treated water quality parameters, treatment options, and chemical reactions occurring within water distribution infrastructure that cause the destabilization of corrosion scale.
This project will explore the initial uptake, challenges and barriers, and longer-term impact of Alberta’s DWSP initiative within smaller communities, and understand the capacity of DWSPs for initiating a culture change at the operations and local decision-making levels.
