Southern DHB Medical Officer of Health Dr Michael Butchard has recommended the Do Not Drink notice (DNDN) on the Waikouaiti, Karitane and Hawksbury Village water supply can be lifted.
This follows a comprehensive investigation by the Dunedin City Council into elevated lead levels that had been detected in the area, finding customer pipes, fittings and tapware leaching lead into the water were most likely the cause of the high lead results at the Waikouaiti Golf Course and the Karitane Bowls Club.
The most likely cause of the high lead result in the raw water reservoir is lead in sediment from a spike in water turbidity. Sediment is filtered out by the treatment process, so does not reach the treated water.
