Staff, patients and visitors have been told to not drink the water at Christchurch’s Princess Margaret Hospital after it was found to be contaminated.
In an email to staff on Sunday, the Canterbury District Health Board (CDHB) said people should avoid drinking the water until further notice.
“Everyone on the site should use bottled water where possible and do not use zips or plumbed in water coolers until further notice,” the email said.
Staff had been asked to bring in their own personal supply of water from home.
“In the immediate situation, we have only been able to source a limited amount until [Monday] morning.”
Canterbury District Health Board chief of psychiatry Dr Peri Renison said on Monday afternoon the contaminant was found during routine water testing of the hospital’s private water supply.
Staff, patients and visitors had been advised not to drink the water until further notice, Renison said.
“We are providing bottled water and are treating the site’s water supply with chlorine,” Renison said.
Renison would not say how the water was contaminated or how long it had been contaminated for.
The hospital, in the hillside suburb of Cashmere, has been blamed for many care issues, prompting calls to fast-track a new mental health facility.
It was supposed to be decommissioned and sold last year.
