2025 monitoring shows dosing with a mean of 0.58 mg/L and some below-target results.
Tweed went nine months without it. Bowral has had none since July 2025, Mudgee since 2020, Nyngan since 2015. Broken Hill is dosed on paper but barely registers. No council voted for any of this. Here's the list.
Brisbane's main treatment plant measured as low as 0.07 mg/L in September. Broken Hill averaged 0.16. Here's what utility data shows about supplies running well below target.
