Flint's mayor Karen Weaver held a news conference today in Flint. She talked about new research which identifies and maps of all known locations of Flint's lead pipes.
The research was conducted by the University of Michigan-Flint.
It analyzed records and maps to create a digital database of the lead service pipes.
Mayor Weaver says the research will help with the city's pipe replacement plan and hopefully restore the residents' confidence in Flint.
She also said lines that service houses with very high lead levels and those with children or pregnant women were at the top of the list.
