The Otago Regional Council has apologised for delays in erecting signs after E. coli was found in Lake Hayes. The bacteria was detected on Wednesday last week but warning signs were not put in place until Tuesday. ''QLDC and Public Health South were not notified immediately following the high reading on 11 December. As a result, a swimming advisory did not occur ... and warning signs were not put up until yesterday [Tuesday].'' It follows a case in Glenorchy last week when people were advised to boil water after the bacteria was detected in the township's water supply.
