Kyabram (Victoria) Manganese

2024/25: Kyabram (Victoria) Manganese 0.15mg/L

“Based on health considerations, the concentration of manganese in drinking water should not exceed 0.1 mg/L

Based on aesthetic considerations, the concentration of manganese in drinking water should not exceed 0.05 mg/L, measured at the customer’s tap. Water authorities are encouraged to keep manganese concentrations as low as possible, preferably below 0.02 mg/L at the treatment plant…

Reviews by the World Health Organization (WHO) and Health Canada found that several human epidemiological studies suggest an association between exposure to manganese in drinking water and neurological effects (e.g. intellectual impairment and poorer neurobehavioural function, including memory, attention, motor function and hyperactivity). Although these epidemiological studies could not establish the level at which oral manganese intake can lead to neurotoxic effects, collectively they provide support that neurotoxicity is a critical effect in humans (WHO 2021; WHO 2022; Health Canada 2019).

Infants, especially newborns, are unable to regulate the levels of manganese in their bodies due to greater gastrointestinal absorption and immaturity of their homeostatic control of bile excretion (i.e. they excrete less manganese) and are more susceptible than other age groups to the neurotoxic effects of excess manganese (WHO 2021; WHO 2022; Health Canada 2019).

Bottle-fed infants may also be at risk of higher manganese exposure due to infant formula which can be fortified with manganese, along with drinking water used to reconstitute the formula which can have elevated manganese levels compared to bottled water (WHO 2021; WHO 2022; Health Canada 2019).

2018/19 – Kyabram (Victoria) – Blue Green Algae

During the reportable period three incidents were notified to DHHS, including Dookie, Kyabram and Tongala which were directly attributable to unprecedented characteristics of a major BGA bloom in the Central Goulburn Irrigation District. The bloom persisted for more than six months affecting sixteen plants directly in GVW’s Central District. BGA created numerous challenges at the water treatment plants resulting in operational changes on a regular basis to ensure customers continued to receive safe drinking water. Water was carted to one of our regulated towns (Goulburn Weir) during the period their raw water supply was impacted by the BGA as levels exceeded the recreational limit. Water carting continued for a month with routine notifications to the customers affected…
