A study of lead service lines in Flint’s damaged drinking water system reveals a Swiss cheese pattern in the pipes’ interior crust, with holes where the lead used to be.

Researchers say the findings underscore how important uninterrupted anti-corrosion treatment is for the aging water systems that serve millions of American homes.
