The Great Lakes contain reservoirs of legacy contaminants, mostly in their sediments, that are vulnerable to resuspension.
Health Canada has some of the strongest limits on lead in the world, but they can’t be effective without testing and a plan to replace pipes.
An investigation showed that five Canadian cities had lead levels in their water on par with those in Flint, Mich. during its peak period of water contamination.
Warning signs in the Newark Health Department after the city learned that lead service lines to houses still were contaminating water.
Newark is the latest US city to struggle with high lead levels in drinking water. Ending this public health crisis will require more money and enforcement, plus stricter water testing standards.
