There are more than 5.6 million commercial buildings across the US, and nearly all of their occupants and visitors have been affected the COVID-19 pandemic. Government orders prompted these individuals to stay-at-home, and many buildings experienced shutdowns and/or low occupancy conditions. Low to no water use has been flowing through the buildings, thereby causing stagnation. Stagnation allows water to accumulate heavy metals like copper and lead, permits disinfectant residual to decay and water to warm. These latter conditions enable pathogens in biofilms to enter the bulk water. These are the risks posed to building occupants and visitors. More than 65 different “guidance” documents were developed and issued in the US since March 2020 due to concerns about unsafe water in building water systems. These differed from one another. Today, commercial building owners need actionable information to reduce the potential for unsafe water in buildings. The presentation will describe water quality issues, building water sampling and flushing considerations.
