Canada just cut the amount of lead allowed in water in half — here's what it means

For the first time almost three decades, Health Canada has updated its guideline for lead in drinking water — cutting the acceptable concentration of the metal in half. The decision is based on the latest science, according to the government body, which worked with the provinces and territories to reduce the maximum acceptable concentration from 0.01 mg/L, set in 1992, to 0.005 mg/L.
