Report: Flint Water Improving

Researchers who played a critical role in the discovery of lead in Flint, Michigan, drinking water say tests reveal another rise in water quality.
Virginia Tech says lead wasn’t detected in 57% of 154 Flint homes tested in November — up from 44% in July. Flint has a lead problem because it used water from the Flint River for 18 months without treating it to prevent pipe corrosion. As a result, the water caused lead to leach from old pipes and into homes. But since fall 2015, the city has been tapped into a regional water system that uses corrosion controls. That’s why the testing results have improved. Nevertheless, researcher Marc Edwards emphasized again that residents still should keep a lead filter on their kitchen taps.
