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. Samples were also taken at the customer’s front garden tap and an additional upstream hydrant at the same time. 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.
