An ice machine and two sinks in cardiac units of the hospital were found to be contaminated with Legionella, officials said. UWMC intensified testing of water systems throughout the hospital, with focus on the areas where the bacteria were detected. In the Cascade Tower, new filters were installed on sinks, fountains and showers. “We are doing everything that we can identify that is reasonably possible to put in place to reduce the risks to patients, family and staff,” a spokesperson said.
