The Horizon Health and Subacute Care facility in Fresno, Calif., has been without water for weeks after a resident tested positive for Legionnaires' disease, according to an article on the Your Central Valley website.
The Fresno County Health Department says it ordered the facility shut its water off "out of an abundance of caution," and is requiring bottled water be supplied to residents.
The health department says the water will need to undergo a thermal treatment or hyperchlorination.
In the meantime, residents with pneumonia are being tested for Legionnaires'.
