A boil water notice for Glenorchy remains in place after E. coli was detected in the town's water supply last week.
The council issued the notice on Friday, a day after several Glenorchy residents addressed the Queenstown Lakes District Council during its public forum, protesting against a decision to chlorinate their water supply for the summer.
Yesterday, council communications and engagement manager Naell Crosby-Roe said sample testing last Thursday showed an E. coli measurement of 2.0 per 100ml and elevated levels of coliforms.
``On a positive result we are required to resample until samples have tested free from E. coli for three successive days.
``Whilst E. coli readings have reduced, coliform results remain elevated and therefore QLDC took the decision to continue the boil water notice until the implementation of chlorination under the advice of Public Health South.''
Chlorination was scheduled for today but additional time had been allowed for it to run into tomorrow, as contingency.
As yet, investigations had not identified the source of the E. coli contamination, Mr Crosby-Roe said.
