GEOSMIN THE CAUSE OF EARTHY SMELL IN DUBBO’S WATER
Geosmin, a natural compound found in water sources has been determined as the cause of the recent earthy smell and taste in Dubbo’s drinking water.
Geosmin is usually more prominent during the warmer months and can affect the taste and odour of treated drinking water. Compounds are generally present in drinking water, but usually below noticeable levels.
While the taste and odour from Geosmin may be unpleasant, it is purely an aesthetic issue and the water is safe to consume. All water treated at the John Gilbert Water Treatment Plant meets the parameters set by the Australian Drinking Water Guidelines. Staff have been using powdered activated carbon dosing units to remove the higher levels of Geosmin to reduce the earthy smell and taste. Some residents have reported putting water in the fridge can help with taste and odour issues.
Dubbo Regional Council appreciates residents’ patience and understanding while staff work to minimise taste and odour issues.
