Mount Isa City Council say they have contacted relevant agencies and authorities after further allegations were made of E. coli being present in the town's drinking water.
The original claims date back to March, when Mount Isa City Council denied there was an issue.
Mount Isa City Council Laboratory Technician Jo Hardie, who samples, tests, monitors and reports on the various types of water being supplied to the Mount Isa community now says several staff members knew of E. coli being present in the towns drinking water.
"I am recommending the immediate dismissal of any Council staff members involved in the mismanagement of Council water infrastructure or that were involved in the cover up of information relating to unsafe water being provided to the public," Ms Hardie said.
A Mount Isa City Council spokesperson said they received a complaint about the town's water reservoirs in March.
"A subsequent complaint was received on Wednesday June 3 last week regarding the same issue and it was referred to the relevant agencies and authorities the moment it was brought to council's attention," the spokesperson said.
"An internal investigation is under way and it would be inappropriate to comment further until the investigation has been completed.
"Council takes all complaints of this nature seriously."
Ms Hardie said there is a chance people may have died from E. coli being present in the water.
"Let me be as clear as I can, there is every likelihood that the mismanagement of Mount Isa water has resulted in death, from either exposure to the incredibly high levels of E. coli at the Fun Park (over a period of at least two years) and from the long term failure to adequately disinfect the towns drinking water supply resulting in conditions like gastroenteritis," Ms Hardie said.
"The most at risk are the vulnerable of your electorate; the very old, the very young and those with already compromising health conditions, including members of the local indigenous community."
Council said they conduct regular testing of town water reservoirs to ensure a safe water supply for residents, with public health and community safety the council's highest priority.
