The OP is trying to link a general statement made by an advocacy group to a GAO audit. They have nothing to do with each other. Anyone with even cursory knowledge of the problem domain knows that any water installation before a certain date is a lead line. States and the EPA mandate and audit representative testing of public water supplies. The criminal negligence in Flint was that, to save money, the state appointed leadership of the City water system knowingly obtained water from an alternate source whose water chemistry caused the lead pipes in Flint to leach out and expose people to the lead in the water. Had they treated the water appropriately, or not changed the water supply, the oxidation in the pipes would have prevented the leaching of lead into the water, as it had for a century. All of this is well documented.
