Flint's Decision to Switch the Water Supply Without Corrosion Controls

Despite their first-hand knowledge of the potential for lead issues in the city's aging infrastructure, city and state officials made a conscious decision -- corroborated by several witnesses -- to ignore expert advice they received that corrosion control treatment should be installed before switching to the Flint River water.

  • Focused on cutting costs while the KWA pipeline was built, city and state officials knew that the Flint Water Treatment Plant was not ready for operation and knew that there was no corrosion control treatment when the switch occurred in April 2014, relying instead on a "wait-and-see" approach to the Lead and Copper Rule and the bureaucratic follow-through.
  • The City of Flint had little knowledge of where lead service lines were located in the city in order to properly collect lead samples.
