UPDATE:

Statement from Mayo Clinic, evening of May 2:
Preliminary analysis has shown that the sediment in the water on the Saint Marys campus came from filtering material from the well at Saint Marys. There have been no reports of illness or symptoms, and the water supply has been tested and deemed safe. Initial tests have not found issues with bacterial contamination or heavy metals.

Water has been deemed safe for cafeteria use. Filters on coffee, ice machines and other equipment are being changed, and will come back online over time.

Additional testing is being conducted for other areas, and results are expected on Thursday. Other areas will be brought online as they are cleared. Flushing has been completed in the Domitilla and Francis buildings. Marian Hall will be flushed overnight.

Statement from Mayo Clinic 11:48 am May 2:
“On Monday, April 30, Mayo Clinic responded to reports of dark-colored water on our Mayo Clinic Hospital — Rochester, Saint Marys Campus. Initial testing determined that the discoloration was caused by sediment. As a precautionary measure, Mayo is advising patients, visitors and staff to refrain from drinking the water or using ice from the ice machines. While we wait for the results from further water testing, Mayo is advising staff and patients not to use water to bathe or shower on the Saint Marys Campus; patients are being provided with comfort bath bags that include items for bathing.


We greatly appreciate the patience of our patients and visitors and commend our staff who continue to provide seamless care to our patients and serve hospital operations despite this challenge. There have been 89,280 bottles of water distributed so far. In addition, 2,880 gallons of bottled cooking water have been provided to our kitchens.

Until the test results come back, Mayo will continue to supply bottled drinking water to our staff, patients and visitors. The water is suitable for hand washing, but should be followed by hand sanitizers that are being placed in bathrooms across the hospital as a precautionary measure. The situation is contained to Mayo Clinic Hospital — Rochester, Saint Marys Campus and the cause of the sediment is still being investigated.”

Statement from Mayo Clinic 9:30 p.m.:
“On Monday, April 30, Mayo Clinic responded to reports of dark-colored water on our Mayo Clinic Hospital — Rochester, Saint Marys Campus and immediately began investigating the source. As a precautionary measure, Mayo is advising patients, visitors and staff to refrain from drinking the water or using ice from the ice machines. Water is running clear in some areas, following a flush of the water system, however, further testing and system flushing continue, and extra chlorine has been added to the water supply as a precautionary measure. Mayo is advising staff to not use water to bathe or shower patients on the Saint Marys Campus while the institution awaits results of the water testing. Mayo continues to supply bottled drinking water to our staff, patients and visitors. The water is suitable for hand washing, but should be followed by hand sanitizers which are being placed in bathrooms as a precautionary measure across the hospital. The situation is contained to Mayo Clinic Hospital — Rochester, Saint Marys Campus.”

ROCHESTER, Minn. -- Dark-colored water was found in the toilets and sinks at Saint Marys campus.

Rochester Public Utilities and Mayo Clinic are looking into the issue to resolve the problem.

In the meantime, Mayo Clinic and RPU are advising people to avoid drinking water at the Saint Marys campus.

Frank Burdick had an open heart surgery more than a year ago at Saint Marys. "I would be concerned if I had to go back there for another operation or something. I certainly wouldn't want bad water," he explained.

RPU says the issue is isolated to the Saint Mary's campus and water in the city is safe to drink.
