ORC’s latest sampling showed E. coli levels at 667/100 ml. Government water quality guidelines for recreational swimming areas state that less than 260 E. coli/100ml should be safe, whereas water with more than 550 E. coli/100ml poses a health risk.

People considering swimming in the creek should hold off in the meantime, pending further testing. Signage advising against swimming in the creek was installed on Thursday. Dr Olsen said that Brighton Beach itself is considered safe for swimming, but advises people to avoid the area where the creek connects with the beach.

Otokia Creek is one of the 25 sites monitored by ORC on a weekly basis for bacteria levels.
