Latest PFAS testing results for the Namoi Reservoir have showed an improvement since the most recent analysis was conducted in January.
Detection of PFHxS has decreased to 3ng/l, below the guideline on 30ng/l, and PFOS is now 4ng/l, below the recommended 8ng/l. PFOA and PFBS were again not detected.
In an update, Narrabri Shire Council said the latest testing results of the Namoi Reservoir have shown PFAS levels as below current guidelines.
“This means that the Narrabri Town Water Supply continues to be safe for consumption,” council said in its update last week.
The Tibbereena Street bore continues to supplement water supplied from the Elizabeth Street bore. The latest testing of the Elizabeth Street bore showed no detection of PFAS, while the Tibbereena Street bore was at 6ng/l for PFHxS; 8ng/l for PFOS and 1ng/l for PFBS (PFOA was not detected).
The Killarney bore remains switched off with testing continuing to show the bore above current guidelines. Results from February 17 saw the bore at 9ng/l for PFHxS; PFOS at 10ng/l; PFBS was 2ng/l and PFOA at 1ng/l.
NSW Health continues to recommend private bore owners consider testing their groundwater.
