Drinking Water and PVC Pipe Wall Biofilm from Simulated Distribution Systems Metagenome. Drinking water and PVC pipe wall biofilm from simulated distribution systems

Five rotating annular reactors were operated as bench-scale simulated distribution systems, fed with chloraminated tap water from a laboratory fixture at the University of California, Berkeley. Reactors were operated from September 2019 through October 2020. On March 17, 2020, the building was closed for shelter-in-place due to the COVID-19 pandemic, leading to a much higher water age in the water feeding the reactors.
