Froedtert Hospital used bottled water for visitors, staff and patients after testing found an "unusual" amount of minerals in the water supply, according to an article on the TMJ4 website.
“While the appearance of minerals in water is not uncommon in new buildings as systems are turned on, we took proactive conservative steps to assure the safety of our patients, visitors and staff,” the hospital said.
Testing of the water at the facility showed an unusual level of minerals in the water supply at the Center for Advanced Care building.
The water has since been found to be safe.
