Most of us expect to turn on a tap and have clean, drinkable water flow out. But in many places in Canada and the United States the drinking water is contaminated. The hardest hit areas are indigenous communities. In fact, 71 indigenous communities in Canada do not have access to safe tap water. We look at two Ontario communities: one still facing contaminated water after 50 years, and another that just got its own water filtration plant. Meanwhile in Flint, Michigan residents have sued the city for unsafe lead levels in their water. Now there are concerns about the children who were exposed to harmful lead levels.
