LOGAN City Council has lifted a ban on drinking water put in place on Thursday after traces of the faecal bacteria E. coli was found in the water supply.
The ban, which applied to residents of Cedar Vale, Woodhill, Veresdale and Veresdale Scrub, was lifted at 12pm on Sunday.
Council handed out free bottled water in those affected areas on Friday.

On Sunday, residents were told to flush all water fixtures, including in-house drinking fountain units, for at least a minute.
All internal water service lines to holding tanks should also be flushed.
All ice-making machines should be thoroughly flushed and washed.

However, council said no changes were required to the hot water system if residents were operating to standard settings of 50-60C.
Anyone with concerns should contact a licensed plumber.
