The Katherine town water supply is primarily sourced from the Katherine River, supplemented with treated groundwater.
Defence is undertaking an environmental investigation to understand the nature and extent of PFAS at RAAF Base Tindal and nearby areas. During the course of this investigation PFAS was detected in Katherine’s ground water. Since ground water comprises only a small proportion of Katherine’s town water supply, Northern Territory and federal health authorities have confirmed that the town water is safe to drink.
As a precaution, Defence has introduced a range of water management measures. These measures will ensure that the Katherine town water remains safe to drink.
Long Term Solutions to Managing PFAS
Defence will continue to work with the NT Government and NT Power and Water Corporation to develop a permanent solution to continue minimising the level of PFAS in Katherine. NT Power and Water Corporation is investigating options for long-term solutions for the Katherine town water supply such as upgrading infrastructure to permanently treat bore water to remove PFAS.
