Environmental officials in Flint, MI say that the lead that has ravaged the city's water supply since 2014 has finally fallen below federal limits.
The Department of Environmental Quality reports that the 90th percentile of lead concentrations in the Flint tap was 12 parts per billion from July to December, which is in line with other American cities. In the previous six-month period, the Flint tap had a lead concentration of 20 ppb. The federal guidelines demand an action when lead levels get to 15 ppb.
Officials do warn that residents should continue to filter their water, as continued work on the compromised water system could cause spikes in the concentration of lead in the water.
