Mayo Clinic’s St. Mary Campus in Rochester, Minn., closed drinking water fountains and advised patients and staff to only drink bottled water, following the discovery of dark colored tap water May 1. According to Minnesota Public Radio, the water was deemed suitable for hand washing, but the hospital provided hand sanitizer to use as an added precaution. Mayo Clinic reported no illnesses related to the water quality.

The clinic flushed the water system and added additional chlorine to combat the problem. Rochester Public Utilities reported that the incident was isolated and did not impact the municipal water supply. Following water testing, Mayo Clinic found the water did not contain harmful contaminants. 

“Preliminary analysis has shown that the sediment in the water on the Saint Mary campus came from filtering materiel from the well at Saint Mary,” Mayo Clinic’s statement said. “There have been no reports of illness or symptoms, and the water supply has been tested and deemed safe.”
