However, Marcel says the health warning signs will remain in place until they have confirmation the contamination has gone.

Test results normally take 48 hours and council are hopeful the warning signs would be removed by tomorrow.

Marcel says the spill near the boat ramp in Pilot Bay originated from a sewer in Adams Avenue and was reported to Council staff at 4pm.
