NSW Health advises that manganese is unlikely to cause any health issues.
The Australian Drinking Water Guidelines values for manganese are as follows:
- Guideline health value – 0.5 mg/litre
- Guideline aesthetic value – 0.1 mg/litre
Council’s operational target value for manganese is 0.02 mg/litre
Ongoing testing confirms that water leaving the water treatment plant has not exceeded 0.05 mg/litre (10 times lower than the guideline health value).
