Many Canadian cities are falling short of testing drinking water for all
possible harmful contaminants, and experts say the long-term consequences could
be detrimental to people's health, a CBC News investigation has found. CBC asked
18 cities in every province and territory to provide a list of the
health-related contaminants they test in their water supplies. Only one — Ottawa
— tests for all 75 substances found in Health Canada's published guidelines for
Canadian drinking water. via
