Canadians have every reason to believe that the water that runs from their taps is beyond reproach: abundant, clean and safe. But the Tainted Water investigation, an unprecedented national collaboration of universities and news organizations, exposed the risks faced by millions of Canadians whose drinking water contains elevated levels of lead, a powerful, insidious neurotoxin, and other contaminants. Coordinated by the staff at the Institute for Investigative Journalism (IIJ), Tainted Water is the largest project of its kind in Canadian history, and possibly the largest student-led project worldwide. The consortium brought together more than 120 journalists, student journalists and faculty members from nine post-secondary institutions and six news organizations and their bureaus over a period of 18 months to report the series. Journalism students and reporters combined their findings and produced local, regional and national investigative features, released as a series of print, digital and TV stories, making international headlines.
