Buildings Reopening After Coronavirus May Face Tainted Water Systems

The coronavirus pandemic has shuttered many buildings. As prospects for reopening rise, so too does the need to contend with water systems potentially contaminated during the shutdown. Stagnant water in pipes or tanks can breed microorganisms like Legionella pneumophila, the bacteria that causes Legionnaires’ disease. Heavy metals like lead and copper also can build up, as can byproducts of chlorination by water utilities. Kerry Hamilton of Arizona State University’s Biodesign Center for Environmental Health Engineering says reopening will require the thorough flushing and maintenance of affected systems, and a good water management plan.
