For six weeks after the February 2011 Christchurch earthquake millions of litres of raw sewage - along with lots of liquefaction - poured into the Avon and Heathcote Rivers. A team of biologists quickly got to work to measure the impact of this catastrophe on life in the Heathcote River and as they tell Alison Ballance, they were surprised by what they recorded over the next few months.
