14 April 2020 COVID-19 Closures Could Make Water Unsafe In Offices and Schools

The COVID-19 pandemic could threaten drinking water safety in buildings that have been closed. Purdue University is working quickly with other research teams to develop guidance for when places like offices, schools, and gyms reopen. 

Water left to sit in pipes can get contaminated with toxic heavy metals and bacteria — like the kind that causes Legionnaires’ disease, another illness that affects the lungs. 

“Now that all of the buildings are closed at this wide scale, we might have to start thinking about it because everyone will be exposed in every building all at the same time,” says researcher Caitlin Proctor.

Purdue engineering professor Andrew Whelton says every building is different — what works to keep people safe in an office might not work for a building that houses people who are critically ill. That being said,, he says there are some actions many building owners could be taking right now to address the problem.

“This would include flushing, routinely, all the water outlets in the building — once a week, at least,” Whelton says.

Whelton says state governments should also consider water stagnation problems as part of their emergency operations for COVID-19.

“What we cannot have is governors saying tomorrow we're opening up everything and everybody go back to work tomorrow — and everybody starts going back to the gyms in the morning where the water is set stagnant for three to four to five weeks and they're going to take a shower in that water," he says. "People start drinking water out of office buildings that haven't really moved in a long time — and so there really needs to be planning to address this.”
