Unsafe lead levels have been detected in children's blood tests in east Otago.
This follows a contamination scare which has resulted in a do not drink notice and emergency water tankers.
Dunedin City Council says it may now be months before the notice is lifted for the residents of Waikouaiti, Karitane and Hawksbury Village.
At a Community Board Meeting last night Otago and Southland Medical Officer of Health Dr Susan Jack said many people had been tested by Public Health South to check the levels of lead in their blood.
