A freshwater ecologist is supporting calls for more research into the connection between the water we're drinking and the risk of bowel cancer.

In the light of a Danish study that found a connection between nitrates and colorectal cancer, Canterbury's medical officer of health, Dr Alistair Humphrey, says it's time for New Zealand to do its own research.

Ecologist Mike Joy agrees. He talks to Corin Dann.
