MONTREAL (AP) - Hundreds of thousands of Canadians have been unwittingly exposed to high levels of lead in their drinking water, with contamination in several cities consistently higher than they ever were in Flint, Michigan.
That's according to an investigative project published Monday that involved testing drinking water in hundreds of homes and reviewing thousands of previously undisclosed results.
A consortium of journalists collected test results that properly measure exposure to lead in 11 cities across Canada. Out of 12,000 tests since 2014, one-third - 33% - exceeded the national safety guideline of 5 parts per billion; 18% exceeded the U.S. limit of 15 ppb.
Canadian officials where levels were high said they were aware that lead pipes can contaminate drinking water and that they were working to replace aging infrastructure.
