The Tibberena and Killarney bores remain switched off after testing in early July showed Namoi Reservoir levels slightly above current guidelines (PFOS level of 9 ng/L - just above the new Australian Drinking Water Guidelines of 8 ng/L).
NSW Health continues to recommend that private bore owners consider testing their groundwater. Information regarding groundwater and testing can be found via their website.
