13/8/20: Manganese – Nicholls
In response to a customer enquiry of discoloured water, sampling results returned an elevated level of manganese from a nearby hydrant.

Both these samples returned low total manganese levels, well within the health guideline limit. Icon Water resolved the level through flushing water from the main.
