A sample from Cox's Creek near Cox's Bay revealed E. coli levels of 590 cfu/100ml - about four times the 126 cfu limit for recreation. Leading wastewater biologist Gemma Tolich Allen said the result showed "dangerously high" levels of E. coli, a bacteria that indicates the presence of animal or human faecal matter in water. The tests - the samples were taken last Thursday and analysed by Watercare's Laboratory Services division - follow a Herald investigation into Auckland's sewage shame.
