(AP) Flint Mayor Dayne Walling is asking Michigan Gov. Rick Snyder for $30 million to help upgrade the city's water system and replace lead service pipes. The funds include $10 million to replace lead service lines and plumbing that can leach lead into drinking water. Virginia Tech researchers testing Flint's water have said residents shouldn't drink or cook with city water without flushing lines or using a filter. The Environmental Protection Agency says Flint's water is within levels allowed for lead.
