What is manganese and how much is acceptable in our water?
Like iron, manganese is a naturally occurring mineral which comes from contact with soil or rock in the ground. Manganese is not considered a health concern unless the concentration exceeds 0.5mg/L. The Australian Drinking Water Guidelines recommend that, based on aesthetic considerations, manganese should not exceed 0.1mg/L. In 2016-17, Busselton Water recorded a maximum of 0.006mg/L of manganese in the water delivered to customers.
