St. Elizabeths Hospital entered its fourth week without running water Oct. 20 after Pseudomonas and Legionella bacteria survived a water system flush Oct. 11, according to an article on the Becker's Clinical Leadership and Infection Control website.
The psychiatric hospital shut off its water Sept. 26 and hired contractors to flush its water system with chlorine.
After the super chlorination of the water system, test results showed evidence of remaining bacteria.
The water is being treated again. Officials don't have an exact date for when the water will be potable.
