High levels of bacterial contamination still remain nearly a month after the first warning was issued.
A health warning advising people not to swim in a section of the Ngongotaha Stream remains in place, nearly a month after it was first issued.
The warning was issued on December 22 and came after routine water samples taken by the Bay of Plenty Regional Council started showing high
levels of bacterial contamination.
The contaminated water puts users at risk of contracting infections or illnesses such as gastroenteritis, diarrhoea and vomiting. The sample was taken at the section of the stream near the railway bridge.
Toi Te Ora Public Health Service on-call medical officer of health Dr Jim Miller confirmed the warning was still in place and the cause of contamination had not yet been identified.
He said Rotorua Lakes Council was looking into the reason for elevated contamination levels.
