From the Vancouver Sun:
Prozac and painkillers found in tap water
The federal government's first study of pharmaceuticals in drinking water will confirm traces of common painkillers, anti-cholesterol drugs and the antidepressant Prozac are ending up in the treated water that Canadians drink, CanWest News Service has learned.

A study by researchers from the National Water Research Institute for Health and Environment Canada, designed to gauge how efficiently plants removed traces of drugs from drinking water, found nine different drugs in water samples taken near 20 drinking water treatment plants across southern Ontario.
