Toronto, ON, July 28th, 2020
As millions of people return to businesses, schools and other institutions that are reopening their doors, health professionals caution about the potential risks in building water systems that have been stagnant for weeks (or even months) due to COVID-19 closures. Stagnant water in building pipes, equipment and water storage tanks is known to cause plumbing issues and concerns related to water quality and appearance.
After months of inactivity, standing water can pose potential health risks due to the accumulation of harmful microbiological and chemical contaminants in the water supply. The Canada Water and Wastewater Association (CWWA) noted that it is the responsibility of each property owner to ensure it maintains the safety of the water within their building(s). The CWWA stated that prior to reopening or fully reoccupying a building, building managers need to flush stagnant water, clean taps and fixtures as well as test the water in their building to be sure it is safe.

The Region of Peel provides additional information about water testing for larger buildings. The website states that testing for chlorine residual should be performed by qualified personnel and that microbial parameters should be carried out by an accredited laboratory for a building or facility that is:
- Complex.
- Serves vulnerable populations.
- Has a history of contamination (i.e., Legionella, which is often related to water in HVAC systems).
“It is important to flush the water system and test for potential bacteria, including Legionella, to safeguard everyone that will be entering the building,” said Christopher Goulah, Ph.D., EMSL’s Legionella Program Director. “Our network of laboratories throughout Canada and the United States provide environmental testing services and sampling supplies to detect Legionella and many other potential indoor environmental quality concerns, including mold, sewer gas, asbestos, lead and radon.”
